Unregistered guest | i have a question that i need help with really badly. i want to purchase a nitro 1000 watt 2 channel amplier to power a 1000 watt rms kicker subwoofer but i have a car with a 70 amp alternator. can someone please tell me how many amps i would need to run the amplifier and if they make universal alternators or performance alternators to fit a 99 kia sephia or if the stock alternator would work fine. |

Silver Member Username: FryguyNova Scotia Canada Post Number: 512 Registered: Jun-04 | The first question is do you have a stock battery. The second is do you plan on running it at full volume for extended times? If you have a stock lead acid battery, that will have to be replaced with a high capacity deep cycle battery. If it's not replaced, when running the system for long periods and with the frequent discharge/charge cycles will eventually cause premature failure of the normal lead acid battery. If you're only running the amp at full or near full volume for short periods (depends on the storage capacity or the battery) you should be fine. The battery will store the power and reduce the overall strain on the alternator If you want to know your systems capacity and when it's near its limit. I would install an in-dash or under dash volt meter and amp mater. This will allow you to monitor the charge and drain in your electrical system. You'll know that when you see the voltage getting low and the charging current rise 20+ amps, you know your battery is getting low and the alternator is starting to do all the work. If you plan on driving around with it at high volumes all the time (Not good for your ears, but that's whole other problem) you will want to install an after market high capacity alternator (or alternators in some cases). Installing extra batteries will always help with the systems capacity and stress. |

New member Username: XanderIpswich, Queensland Australia Post Number: 1 Registered: Jan-05 | um, i know this has been asked so many times before and for that i apologise. But, with car head units right? I have an old computer power supply running at 12 Volts and 9.5 amps, however when i connect it using the original switch from the PC case, it shags up. it doesn't even light up my head unit the headunit's a Kenwood KDC-MP4026. It's a new one and it's frigging good but i can't work out how to power it. Help please. |
|
Silver Member Username: FryguyNova Scotia Canada Post Number: 533 Registered: Jun-04 | It applies to AMPs also. What size amp? I would say that the power supply is too small. If its an old AT PSU with the switch on a wire, they will most likely have problems. |

Unregistered guest | i've been reading these forumsnfro bout a month.. and i think im ready to go at it.. but before i shell out some change into this project..lol the specs on the amp are Fuse - 60 Amp (4 X 15A ATC) Crossover - Yes Protection - Thermal, Short Circuit, Overload Max Power Output - 500w Power @ 4 OHM 300 x 1 @ 4 ohms Power @ 2 OHM 400 x 1 @ 2 ohms Signal To Noise Ratio - 115 Battery Voltage Range - 10.5-14.4 and i was wondering would i need to do your (FryGuy's) ATX mod to 2 supplies.. or could i only use one but dont cut the amp all the way up and get away with using it that-a-way? and (i think this was answered as well but i dont think i caught it).. is it possbile that i can cut the amp off with the power suply's Switch on the back or would i have to follow the other way to use a switch on the power supply? Thanks in advance.. and sorry if i asked a question that was on here before.. Gamer Gee |

Silver Member Username: FryguyNova Scotia Canada Post Number: 538 Registered: Jun-04 | You could get away with one power supply if you don't intend runing the amp very loud/hard. If you bridge the BAT to the REM with a short wire (this will hold the the amp on) and the PS_ON to the ground on the PSU (to hold the PSU on). Then the switch on the PSU can be the main power to turn the power on or off as you want. Hope that answers your question. |

tpot Unregistered guest | hello, just went out & bought (1) 350w ATX power supply for 20 pounds. ..followed fryguys guide posted above to hook up my 300w active sub. just wired PWR & REM together, wired together ground&pwr_on on the power supply, and finally +12v (yellow) to PWR, and ground (black) to GND. BAAAAAASEEEEE !!! works a treat ! seems to work fine even up a high volume. It is so loud. try it !! thanks again for the info. |

OUTLAW11 Unregistered guest | Hey whats up, i got a 480 watt sony xplod amp and 2 phoenix gold 10s i want to add to my home stereo system.i am running the the amp of the output from the tv and i have the 12v power it needs but what would i use for the rem. wire. |
|
Silver Member Username: FryguyNova Scotia Canada Post Number: 556 Registered: Jun-04 | Use a short jumper from the REM to the BAT(+12)to hold the AMP on. The you turn on/off the PSU and the amp will turn on/off. |
|
tpot Unregistered guest | yeh thats what i did. Iv got the sub pointing directly into the sofa now ! its great. Ill post a pic or two when i get a camera. -also found out that my sub won a gold medal award in a magazine (its a bombA300 made by focus), and i havnt got a car at the moment so its good to make use of it. cheers again. |

New member Username: SimitchPost Number: 2 Registered: Sep-04 | Hey I want to run a sub from my 4 channel amp, which has got a 'front' and 'Rear/ sub' aux socket. However the Head unit ive got only has one set of aux out to the amp so i cant put in another run in solely for the sub. Would i have to split the aux lead going into he amp using aux splitters so it can be split into the front and rear channels. would that work in the same way as having a seperate cable run. |

Unregistered guest | Is it possible to hook up six 6x9's to a 110 watt stereo amplifier |
|
Silver Member Username: FryguyNova Scotia Canada Post Number: 602 Registered: Jun-04 | That amp can only power two or mabe four of them properly, its a small amp. You could run four of them if the amp can run down to a 2 ohms load. |
|
New guy Unregistered guest | i have a normal teac home stereo and i have two 10" pioneer subwoofers and an amplifer. the amplifier is hooked up fine but i dont know how to connect the subs to the amp, any help would be greatly appreciated. |

New member Username: OrlingPost Number: 2 Registered: Mar-05 | FryGuy, I did what you've discussed - I got me an ATX ps, powered my PIONEER TS-WX75A sub with built-in amp, connected to DVD player....but alas - noise!!! Strong humming noise! And it's not only coming from the sub, but from the sattelite speakers too! The sub doesn't give any noise when I pull out the RCA cables, so noise seem to be coming from the DVD player or something... I've read about the ground looping thing...how can I fix that? Please, help! |
|
Silver Member Username: FryguyNova Scotia Canada Post Number: 615 Registered: Jun-04 | With the RCA cables removed and the noise disappearing, that is a sign that you have a ground loop feed-back problem. If you pickup a simple passive or even better an active type ground loop isolator from your local audio dealer this will eliminate the problem. They can cost about $10-30 CND. |

Unregistered guest | I have a an old car radio that is supposed to use one 8 ohm speaker. The speaker blew and I found the same size speaker but it is 4 ohm. Is there any way to make this work? |
|
Silver Member Username: FryguyNova Scotia Canada Post Number: 619 Registered: Jun-04 | Two wired in series will be 8 ohm. In parallel will be 2 ohm so watch how you wire it. |
|
New member Username: OrlingPost Number: 3 Registered: Mar-05 | Fryguy, Thanks a lot for the help. But here's what I did and it decreased the humming noise: I noticed that I have speaker input line on the bass-tube, so I wired those instead of the RCA. Now the noise disappeared (or if not completely, at least substantially), but the new problem is that the sound (signal) seems to be too weak - I mean, I really need to crank-up the volume in order to hear some strong bass. Could you help? Here are the specifications: speaker line input to bass tube = 5V+5V/5kOHM, DVD player output = I don't know exactly, because the book with it is not really informative, all it says is literally this the way I've written it, on one line: "Audio: 5.1 channel 0.5Vp-p mix stereo 2 Vp-p". Can you help? |
|
Silver Member Username: FryguyNova Scotia Canada Post Number: 621 Registered: Jun-04 | I'm not sure what brand or model of bass tub you're using but it should have a gain/input sensitivity knob to adjust the input sensitivity. When you change inputs you need to adjust that knob to match it to the different input signal voltages. EX: When the source signal is at max the sub should be pushing at max volume also, that's what the gain/input sensitivity knob does. |

New member Username: OrlingPost Number: 4 Registered: Mar-05 | Dear Fryguy, I'll try with the "simple passive or even better an active type ground loop isolator" that you mentioned. Unfortunately I'm in non-English speaking country, so how can I explain what exactly I need? Is it something that separates the grounds on the cable or what? |
|
Unregistered guest | I have three 10' inch subs built into a bed box frame, in one box seperated, two subs are left/right rear channels and middle for sub. And before I insulate it, I need to know the proper port tub size/length for the speakers, the size of the three are same (20'w/15'h/24'l ( front to back) I tried uploading a picture but it says ( the maximum allowable upload size (which is -1 kilobytes). LOL I send a picture of it completed later. |
|
Silver Member Username: FryguyNova Scotia Canada Post Number: 622 Registered: Jun-04 | Orlin Grigorov, Yes it isolates the grounds electrically so that it eliminates ground loop feed-back loops that causes the hum or buzz noise. |
|
Silver Member Username: FryguyNova Scotia Canada Post Number: 623 Registered: Jun-04 | Best to consult the documentation of your sub for a port length that they recommend. You can also get the Thiele-Small Parameters to calculate your own custom tuned port from this documentation also. |

New member Username: Capitan_jackPost Number: 7 Registered: Sep-04 | Hi Johnatan sometimes ago i saw your article and you really help me.i have 1000 watt sony amplifier with 15" sub and 5 ATX Powersupply and my bass is very hard.now i have question can i use two 12 inch 8ohm normal speaker instead the sub? |

New member Username: OrlingPost Number: 5 Registered: Mar-05 | Dear FryGuy, I've implemented the bounceless switch that you have described in your document. It works, everything is fine, but I've noticed one problem - sometimes I turn it on, and it doesn't turn on. I mean, I have to unplug the cable and plug it again, and then it works on-off-on-off again. I've used capacitor with value 100nF - that's what they gave me at the electronic shop when I showed them the circuit. The wires to the switch are pretty short - within 5 inches. Maybe I should put capacitor with another value? Please, help! |
|
New member Username: OrlingPost Number: 6 Registered: Mar-05 | One more thing - where can I connect a LED so that I know when it's on and off? What specs does it have to have, and do I need a resistor? Thanks a bunch! |

New member Username: Mtv01Moline, Il Usa Post Number: 1 Registered: Mar-05 | i am thinking of putting my 2 12" woofers that i have in some home speaker box's that i have. I want to run an amp to them, but i dont know what i need to convert the home power so i can run my 8gauge power wire to the amp. Is there something i can buy to convert this power, tryin to go cheap. Thanks |

Unregistered guest | Well Mike, For you to understand the answer you need some basic knowledge. Ohms law is E=IxR E=voltage,I=current,R=resistance. Wattage=volts x Amps. Your source supply voltage is 12 volts which is 1/10 of what comes out of the wall. Lets say your amp is 120 watts.. This means that your current would be 120/12 or 10 amps. So you can goto your local electronics shop and spend a wad O cash or you can simply duplicate your car. Take a car battery and a booster/charger to keep it charged. Keep in mind that a car battery is really nothing more than a large capacitor in this instance ( techs go easy on that statement..it suffices to explain the point)Car batteries are not designed to be discharged a great deal. Also the current draw from the amp will be affected by how you wire your speakers (4ohm or 8ohm or 2ohm)and the music output. Base thumps can make your lights blink. Personally I would by a set of computer speakers with a nice sub like Sound works from creative or similar and power the deck from a computer power supply. Your second problem is that speakers have a design concept in mind. They require preasure equalization in both directions. Again this depends on the design of the speaker as to how much or what form produces optimum results. Normally, all speakers for car audio come with a spec sheet that explains this preasure called VAS. This is how techs determine the size of the box, the style of mounting or type of enclosure. Professional enclosures are made with MDF wood, screwed every 3 inches and glued to keep the box sealed. To give you an idea based on spec... A sony 12" sub at 4 ohms requires aprox 3 cu ft box with a tuned port ( 2" Diameter) tube at about 6 to 8 inches long to produce a tuned frequency near 40 Hz. other wise it will sound like granny on the toilet after speghetti. If you are interested in learning then read, ask questions and visit an install bay at your local car audio shop..but what ever you do. don't walk blind ..I guarentee you will be disappointed with the result. |
|
Unregistered guest | Germs 24... Your best load source for a computer power supply is a light bulb that operates at 5 volts..not an LED. To really understand..Look at the label on the power supply. It will say 12volts at 5 or 6 amps +- and 5 volts at 1.5 or 2 amps. Now..5 volts x 2 amps = 10 watts. So..your answer is a 5 volt 10 watt light bulb |
|
Unregistered guest | Hey Charlie..The easiest way to get the schematic is to goto the dealer and ask the mechanic to print you the page from the computer data base. Personally many of those cars in that era were enhanced with amps at the speaker. First determine if the car has this. If not, just disconect the negative terminal from the battery. Mak a tester with a 1 1/2 volt battery, and test the wires till you here the speaker pop. This won't hurt the speaker but use a AA battery...nothing larger. ( why the negative terminal.. It forms a good habit. newer cars have computers, decks have security..nuff said. |

Unregistered guest | Hey Orlin... Did you solve your noise problem. If not explain what your doing again. Is this a car install or a home install and what equipment are you using |
|
Unregistered guest | I love to share tech. You all have a talented tech in Fryguy and your fortunate as most techs arn't really techs. This is good to see. Reading the many posts there are a few things or tips I'd like to share. 1)Computer power supplies may require a sence voltage to actually turn on..This is usually the white wire. 2)home devices like VCR's, amps TV's etc all have a factory diode or resister tied between the chasis and the nuetral that can inject noise 3)Most input output devices for home audio can very from 160ua to 240ua. The diferential will cause noise. sellect different manufacturers carefully. 4)cable TV will represent up to a 40 volt AC differential between the ground of the incoming cable and the ground of the device its attached to. use 2 75ohm to 300 ohm cable adapters to isolate the cable ( just wire the 2 300 ohm ends together) 5) 2 audio output transformers wired the same way makes a great RCA to RCA isolator. 6) A cheap 2nd amp wired to take advantage of the hafler effect can make a really shitty stereo system sound a whole lot better. split off the record output of the amp (home system) or use RCA Splitters ( car) to feed the second amp the stereo signal. Take one speaker or 2 wired in series and connect the 2 remaining wires to the positive terminals of the amps outputs. don't use the speaker ground terminals. what you end up with is differential of the stereo signal..sort of like surround. note that a mono input to the 2nd stereo amp will provide no output as the left will cancel the right. 7) When wiring your car audio system,keep all the RCA cables on the oposite side of the car than the battery sits and keep the power cables on the same side as the battery. 8)Don't tie your home stereo cables together with the power cables. Tie the RCA cables in large loops and the power cables in small loops and keep them separated. |

|
Unregistered guest | First of all you could hook up your computer speaker output to the amp but I would isolate the rca inputs as I mentioned above Its really easy...Just take two 1 to 1 ratio audio transformers and solder rca jacks to both ends...then hotglue the two transformer bodies together for stereo. The computer has a floating output. Power the amp with the power supply listed Dustin mentioned will power the amp to a fair volume with 24 amps of juice. The really loud volumes and heavy base may be too much for it. You may want to consider a battery source as a capacitor and even some real capacitors will help 5000 Mfd electrlytic 200 volt( if you can find them cheap...call a reclamater in your area). I would prefer the battery. Just take a car battery with a cheap booster charger in a RV spare battery box and your stylin... |
|
Unregistered guest | Hey Dustin...Dude...slow down man...GET A METER... Go to Google and search for "Power supply Pinouts...Or Take any computer motherboard manual and look at the pinout for the power molex plug. This will tell you what wires will supply what voltages. Because most power supplies utilise multi taps for different voltage references...Its possible to get some substantial voltages if you connect the wrong combination....SO DON"T DO IT> Some computer power supplies require a sence voltage reference to turn it on Pin 10 used with any of the grounds will give you 12 volts. grounds are pin 3,5,7,13,15,16,17,. Pin 14 is PS ON and pin 8 is PWRGD. Forgive me saying this but if this information still leaves you confused ...don't use a computer power supply. Look guys...Sometimes its fun to experiment and I understand that money can be tight...but the best cheap sound system for anything would be a half decent computer speaker system. Try looking at "EDIFIER". This new product line is inexpensive and good for what they are. I can buy there top of the line 6.1 oak finished model for $299 canadian. The Altec Lansing 4 point with sub system is awesome for the 60 dollar cost (canadian) and produces an SPL of almost 90. It will cost you more than that for a decent computer power supply and I guarentee you will shake the hell out of any car with those. If you are a true audio file and come back with the Klipsch rant then you shouldn't be reading any of this anyway...Its the dollar thing. Were trying to do this cheap. |
|
Unregistered guest | For Needshelp9.... Here is the math...240 watts at 12 volts = 240/12 or 20 amps. Now the amp is going to go over that possibly and you want breathing room so lets say 25 amps for comfort. I solidly recomend using RCA islolators to reduce noise. Use the preamp out on your receiver or the record output from the receiver to feed the power amp audio The battery solution is still the cheapest way to go. If you have the cash and tech knowledge and feel like playing...Goto a reclamater (garbage dump) and look for a large transformer that will solve the problem..bring a meter and check the thing before buying. Build a hefty regulator circuit for it. get a couple of large caps from the same reclamater ( 5000 Mfd 200 volt ) filter the crap out of it. Downside!!...It will be the size of your lawnmower... Upside!!.... it will blow the clothes off your girl friend at full volume. If your not sure how ...ask and I will post a schematic for ya. Actually I can post a schematic for most anything but be nice. Please don't ask for the running schematic of your TV set. I also post interesting howto's on my site at http://www.angelfire.com/film/vesarious/index.htm goto the tech page section. |

chris23465465 Unregistered guest | do i just need a 12v transformer to power a 400w car amp in my house? should i put a fuse on it? |
|
Unregistered guest | Okay LoL the same question have been answered a couple of time (right Fry ?)...hehe...so I resume what I understand... I don't want to pi** you off lol My car amp's fuse is 15A so I get a PC PowerSupply of 12v @ 15A (or two PS of 8A...or 15 PS of 1A...whatev)... I tie all the yellow leads of the PS(PSs?) to the PWR and RMT of the amp and the black ones to the GRN... I link together the 14th & 15th pins of the PS so he will stay on... It's supposed to work. (didn't try it yet, waiting to make sure) Am I right ? Is there a way to keep the settings of the head unit while shutting down the powersupply to avoid overheating ? Can I put like 2 PS of 10A for a 15A system or something gonna blow ? Can someone send me an email ? lol ! Peace !! |

Unregistered guest | Who said 16 year olds are stupid, well i proved yall wrong, i hooked up my power supply with the radio and works like a charm, thanks t frys packet and my technoknowledge, i just brought a antenna from pep boys for 11.99 a good one to. |
|
New member Username: ArcadeboyPost Number: 1 Registered: Apr-05 | About the ATX power supplies. They all have on/off switches on the back as well. After we connect the PS_ON and the GRND together, will that switch still work so that I do not have to un-plug the power supply when I am not using it? Also, how much can a power strip handle? Is is ok if I plug in the ATX power supply which is connected to an amp and another atx power supply for a computer in the same strip? |
|
lofton316 Unregistered guest | the switch will still work, but you need ps_on and ground togehter, i have my sony xr-ca330 hooked up, i just click the back of the power supply to turn the radio and the power supply off, Note when you turn off the power supply all memory will reset after 30 seconds. Now the rest of that stuff i dont. What do you mean by strip? |

ATX POWERSUPPLY SETUP AMP AND HU just buy a fan 80mm or what ever cut the connector off and you should be left with a red yellow and 2 black wires for an amp the yellow wire goes to (power or B+) the red you dont need inless you want to use an actuall switch to control turning it on and off while the computers on the black will go to the ground the other black you wont need next take a like 2-3" piece of wire strip both ends and put one end at power and the other at (remote) this will make it so that every time your computer is turned on the amp will also if you want an actuall switch its a little more difficult yellow to power red connect a 2-3" piece of wire to the end of the red and connect other to the remote reminal there will be a second wire on the switch connect that to power(where the red wire is connected to and black wire to ground to do a HU there is 4main wires besides speakers coming from the back of the headunit Memory / Constant 12V(+) Yellow Switch / Accessory Red Ground / Black amp Remote / Blue yellow gose to yellow from power supply to HU red from the HU connects with the two yellow wires black gose to black blue you can use to turn on your amp speakers go to speakers and speaker wires with a black stripe will be - solid color wires will be + to add a switch to turn the HU on and off while the computer is on yellow to yellow and connect one of the two wires coming from the switch together the second wire coming off the switch connect a 2-3"piece of wire to that second wire then connect the other end of the 2-3"wire to the red wire and the black wire gos to black wire to use the HU's remote amp (blue wire off the HU) connect that blue wire to the remote on the amp and they will all be switched on at the same time using an actuall switch or using just the HU turn on when the comp turns on im missing my whole english pirod to help you DipSh*t's out email me if you cant figure this out damnrusiancommys@netscape.net |

shaska Unregistered guest | Steven12391 this will not work because the car batt will die in about a day there is no alternator recharching the batt as in a car thats why you should just use the computer to run the HU and to use the RCA's there should be two sets of red and white theres an input and an output set to plug these subs into your soundcard after getting the power and what not to the amp figured out you need to plug the RCA's from the soundcard to the input on your amp |

New member Username: ArcadeboyPost Number: 2 Registered: Apr-05 | Ok, after removing the unnecessary wires from the psu board, what is the best way to connect all the yellow wires from the same psu? is it easy to just cross the lines and twist them? also, if i want to put them all into 1 wire to power an amp, what kind of wire should i use, is there a certain thickness that would be best to connect to the amp? |

smoke1 Unregistered guest | For those who would like to use a power converter to power your CD player and amp for subs I think that I would go with Pyramid 17-amp converter. 17-amp continuous output with a 20-amp surge with a built in cooling fan for $110.95 from JC Whitney. Item # 38SB3682Y. I would put a fuse link in the power wire of your CD deck, your amps power wire should already have one. It may work and it may not. Maybe some of you who know more about electronics than I do have something else in mind. |

Anonymous | I'm trying to hook up my sony receiver to my motorcycle and when i turn it up the unit kicks the sound off. I did do something kind of "iffi" by connecting the red main power wire to a very small guage red lead that turns on when the bike key is turned on ... Would a direct connection or larger guage line connected to the battery give my amp more juice so that it might not kick off? |

Unregistered guest | For Sale: 2005 Planet Audio Class D monoblock audiophile power amp (for driving subwoofers). It is 600watts/Channel, and two ohm stable. Has remote Bass adjustment, low pass filter, subsonic filter - both 24DB octave slope, bass boost, etc (the list goes on and on). Amp rated 100DB and comes with it's own "Birth Certificate" of performance. Still have box and is under warranty for quite a while. Also have FOUR 10" one month old Street Edge subs in two separate boxes that are 8 Ohms each. With all four wired parallel the amp operates at 2 ohms and delivers the most power. I am selling these as a whole or just speakers/amp (depending on what you already have). I am upgrading system to four 15"s so this stuff obviously needs to go. It is all hooked up still so you can hear it before you buy it..that is, of course, unless someone buys the amp first. Email me for more specs or with any questions. The amp new was 314.96. will take 200 for whole thing (amp + all four subs), including wiring. iomega@grm.net |

AudioFreq Unregistered guest | Yes.. I REKON you could try to get audio off a ganged pair of ATX's for maby 700-1200 watts... That will 'nearly' run my mono block tube amps for the mids and highs. Sigh.. Could just do the easy thing and get a Deltek 3300 watt UPS like I did. ☺ I got it CHEEP from a salvage place in KCMO. Has dual 60 volt rails (12V x 5 x two)for the powersupply.

New member Username: Mules4youPost Number: 2 Registered: May-05 | If you under power the amplifier it burns up. Why? Because amost all amplifiers (esp on cars) Have Voltage Regulators and when the voltage drops or becomes to high the voltage regulators burn up, and after they burn up If your lucky it will cut the power to the rest of the amp (but haft of you dont understand how to fix this anyhow) But if your an unlucky Fu*k, It will short out and fry the rest of the amplifier and even what is sending the singal to the amp (tv, preamp ect For powering the amplifier You need to be VERY careful. Strange Sh*t happens when you move something from battery to running on AC or the other way around, Mostly from grounding Aslo Try to get a power supply that says its Isolated or filtered or both I can build a simple AC to DC converter for 10 bucks that will handle 300 Watts but that dosent mean it would run your amp, Probably burn it up. because It wouldnt be filtered and would still have AC left in it. Batteries are the BEST filter, they wipe out 98% of Line noise (if they're hooked properly) AND "I want to know if hooking up a speaker capable of 160 watts onto an amp channell capable of 300 RMS Watts will blow the speaker." Tell me the Voltage of the ouput of the amplifier and the Impendence of the speaker and I can answer that question |

Jason Mantey Unregistered guest | Here is a question that I think will help many people out (including myself). About how many watts/amps are used in various parts of the audio system for reasonable volumes? For example, a chart like this: CD Player: ~2A (my guess?) Speakers (w/out amp): ~4A (max)each (my guess - 50Wrms/12v?) Amplifier: = #watts/12v sub: = #watts/12 The reason I ask is this: I can get a 12V Power supply for $40 (Pyramid PS-14KX -- 13.8V@12A(cts), 14A(max)) Or I can get a 4-500W atx power supply for $30ish (USD). I dont have access to a ammeter on my multimeter. I need to know how much current I will be drawing in total. I think if someone could answer this question, A great deal of people *should* understand without asking short redundant questions. Another quick question. I know that most automotive 12V PSUs run ~13.8V. Is the same true for computers? If not, a 13.8V psu might be better than a atx 12v. Thanks for any responses. If you need clarification, just ask.

They can be had at www.crutchfield.com or http://www.partsexpress.com/webpage.cfm?webpage_id=3&SO=2&&DID=7&CATID=48&Object Group_ID=195&filter=stopper What bass blockers do? It's what it sounds like, they block bass from your speakers. You will have a choice of when you want to block bass or more correctly at what frequency (Hz). Parts express has bass stoppers(bass blockers) that start at 300/150 Hz. This spec pertains to speaker impedence. If the speaker is 8 ohms the bass is stopped at 150 Hz 4ohms then 300 Hz. They have to be installed inline on the positive side of each factory speaker. A point I should make is bass energy starting at 20Hz upto 2000Hz is non directional and in my opinion is useless in anything smaller then 8" speaker but most speakers as small as 4" can produce a modest amount of bass even at 50 Hz. I would recommend blocking as much bass and upper mid bass from your factory speakers. Parts Express have a model thats 1.2KHz@ 8ohms and 600Hz @ 4ohms, this is where I would cut off my factory speakers if I had the same problem. 1) cause most factory speakers are anything but 4ohms. They can be anywhere from 6-16ohms, using a multimeter is usually the only way to determine Factory or oem speakers impedence. The impedence will determine the actual cut off frequency. Take the 600@4ohms spec as a reference. Eg: If your factory speakers are say like General Motors usual spec of 10ohms, then your cut off frequency will be far closer to the 1.2KHz@8ohms, so lets say 1.4KHz. 2) If you don't want to degrade and colour your sound with crackling speakers block the bass as much as you can and let the mids and Highs come from your factory speakers. This will also greatly relieve stress and heat from your factory amp(s). Until you can afford or want to upgrade them for some dedicated component speakers and amp(s). " Like a 6.5" speaker and a dash mounted Tweeter for the Highs with crossover... " but thats beyond the scope of your question and my dream not yours.LOL It is normal for home speakers and car amp makers to use a crossover to stop bass from getting to the smaller speakers. A cross over won't help you with your factory amp and speakers unless you can wire it in either with RCA jacks or know where the outputs are to the speakers under the dash. The bass Stoppers at Parts Express are a mere $2.95US. No worries if you live in Canada or elsewhere in the world and don't posses a Visa/Mastercard or other credit card look for your local car stereo install shop. Then they should have some or be able to order you some, albiet it will probably cost you a few bucks more. OLO |

Cmdr Gonzo Unregistered guest | This may be off topic or already addressed, but I'll take the chance....I'm getting ready for RockFest (www.rock-fest.com) and am thinking about our upgrading our campsite sound from a boom box to my old college (now the garage) stereo. My plan would be to use a marine battery with a 110 converter through a cigarette lighter plug w/ a 15A in-line fuse. This is NOT a high-powered unit by any means, btw - a very basic ol' technics receiver. I'm assuming this is a viable plan. My dilemma is this - how long should I reasonably expect to be able to run it w/o a recharge? I'm figuring I can fire up the truck and charge the battery if/when it goes low. Any advice/input is welcome. Cmdr Gonzo |

I got a small wire leading from the +12v to the remote, and I know to put the negative in the ground but when i put power to it, the amp never turned on! What's up? And Fryguy said in another forum that your power converter must be a Input:120vac Output:12vdc power converter and must have the right amperage for your amp. You get the amperage from the fuse next to the +12v on the amp. The amperage my amp needs is 20, and you cant buy a Input: 120vac Output: 12vdc 20amp power converter, so what the HECK am I supposed to do?

JohnnyJ Unregistered guest | I have been researching about supplying power to a car amplifier in a house for almost a week non-stop now, but still I haven't been able to obtain the information I seek. I recently bought a Pioneer TS-W5000SPL subwoofer (full specifications: http://www.pioneer.co.uk/uk/product_detail.jsp?product_id=3469&taxonomy_id=25-13 0) and a Pioneer PRS-D5000SPL amplifier (full specifications: http://www.pioneer.co.uk/uk/product_print.jsp?product_id=9489). The subwoofer handles maximum 5000watt/2000rms. The amplifier handles 3000watt/1500rms maximum. The amplifier (the sub also) has awesome technology, performance and features, if you would like (or need) more information, visit the specifications. Anyway, my question: How can I power this amplifier through a normal house wall electricity outlet? I have read about PSU/s from PC's, car batteries even using a UPS. I know that PC PSU's cannot supply the amps I need for this amplifier... I don't want to limit my amplifier/subwoofer, never mind as much as this would cause it to under perform. What is the best way to power this amplifier in my bedroom? My goal is to have some speakers and the subwoofer running off my amplifier, with a car head unit controlling the sound - in my bedroom, through a standard house wall electricity outlet. All this WITHOUT under powering my amplifier too much, if only powering it at 3/4 of it's full capability that's okay, but preferably not - and DEFINITELY nothing less than 3/4. Will it even function correctly and be stable, or will it overheat or blow up or something if I don't supply efficient power (amps.. whatever) to it? Thanks in advance, I really appreciate any help! |

spencer17 Unregistered guest | i have a 220 watt jensen ampthat i want to hook up to my 2 6x9 and 2 6x5 in my car . would i hook it up like a regular amp and how do i attach the speaker wires to the speakers them selfs |
|
GrandMasterB Unregistered guest | well let me tell you first off you need to open up a old computer power suppy cut out all the wires find the resisters marked ac 1.7 or adc 5.7 hook up the power from one to the other in my experience i have found that by using2 power supplies, you can run more power and bye increasing the power output you can increase the speaker load. In my setup i am running the dual power supply setup, my kenwood 800watt amp, my kenwood deck, and my 2 1000 watt volfenhag zx-4712 dvx. even though i found this to be the best setup . i did try to rig up a car battery along with an alternator ran by an electric motor that was used for a grinder in my garage. the setup with this method was close to the setup from my car. th only problem wiht this method is that the amp kept overheating and blowing fuses. when this setup did work it did work great. I however reccomend the dual power supply method as described above. if you need more info you can contact me directly at dannybuck2001@yahoo.com |

Unregistered guest | okay i have a serious and sad problem i just went out today and bought myself a rockford fosgate 200watt punch mono amp, and within 20 minutes i blew it! heres the story, i took the ground and the positive and hooked it up properly to the battery But, i took the start up wire or the wire thats just ment to have a sudden shock of power to start the amp and i stupily took it and put to te positive pole on the battery so it had constant power. and there for screwed up the amp, now im wondering if this is internal or if this can be fixed by maybe a fuse or a restart button? neither of which i can find anywhere on the amp, if someone could tell me where the fuse is on this particular amp and tell me how much i screwed this thing up, and i know there are some smart genuses in here if anybody knows what i did to this thing and they think they know what could be wrong that would be a great great help...PLEASE ANY INFORMATION WOULD BE EXTREAMLY APPRIECIATED! |

Unregistered guest | Hi. im new to sub systems. I just purchased a kicker sub (Solo-Baric L7) and a a kicker amp (KX6504.2). I hooked them up and everything ran fine till the amp started overheating like crazy.Its even hotter on the bottom. I could frie an egg on it. Everything is clear of the fans so I really don't understand what the problem could be. I bridged the amp so ist shouldn't be overworking for the sub. If anybody could help me I would appreciate it. |

Unregistered guest | I was recently doing some work on my car system however while I was doing the work the 12v and the ground ends of the cable touched, the result was a big spark. The fuse is not blown and niether are any of the car fuses. At the time that this happened my amp was not in any way hooked up to any power. I have run this amp in another vehicle to make sure that it is fine. I have used a voltmeter to test for any power going through but I found there to be none. This one has me completely confused because nothing seems to be broke, there just isnt any juice |

JohnDamian Unregistered guest | I have a Rockford Fosgate 800.4 (4x100rms). I hooked it up to (2) 12" Pioneer IMPP subs. I have them in my room, and they will make the whole house shake. All you have to do is go to Kmart, and buy a battery jumper/power source. Run your power/remote wire from your amp to your positive on the jumper, and run your ground from your amp to the negitive on the jumper. Then run your RCA cable from your stereo to your amp , and now your ready to Booooooom! |

photn Unregistered guest | hi, i have a stock car stereo with no RCA outputs, i already have a clarion pro audio series sub 12", and a schnieder 2 channel 500W amp, now i knowthat it wont work without RCA out put, but if i get a dvd player or a cd player with RCA out puts on them, connect it up to my amp, then get a FM transmitter and connect it in the head phone jack port, will that work, and yer i know that i will only work off the dvd player, but i willalso soon put a screen in, what i need to know is will the dvd player with the RCA outputs get the sub going normally, or am i just wasteing time?????? |
|
JohnDamian Unregistered guest | Dear photn, All you have to do is plug your RCA's at one end to your amp, and then at your stereo end just cut your RCA plugs off. Then wire your RCA cord up to your L or R front or L or R Rear speaker wire coming out of your stereo. It's just that simple. |

Silver Member Username: Efil4zagginChi Town, IL Cook Post Number: 113 Registered: Dec-05 | Take the yellow and black wires on the psu connect the yellow to the B+, the black 2 the ground connection, and for the signal wire U could use the red or orange wires, but the easiest way is to take a small wire and run it 4um the yelllow wire to the REM terminal on your amp. Connect some RCA's from a srereo or home theater and hook up the subs and enjoy......Oh yah don't 4get if the amps max wattage exceeds the PSU it will go into protection mode and it may get your house wiring fucked up. |

Caleb Shukis Unregistered guest | Hey, I have a question... I've got two 12" Pioneer subs with an 800 monoset AMP in my car. Now, I don't know anything about hooking them up to my home theatre, which is what I want to do... I've got a Sony surround system of 600 watts, with a self amplified sub of 100 watts. For shits and giggles I got myself a Dual Brand 10" Subwoofer of 450 Watts off of ebay for extremely cheap, I got it cheaper as it's an older model. What do I need to do to hook it up to get decent sound quality out of the sub? The RMS Wattage of the sub is 150 with a single voice coil, so I won't need a very large amp, just something small to run it... Oh, and it runs at 4 ohms. I'm not big on speakers and subs... but what would it sound like if i just wired the sub to the reciever? The hookups for the sub itself are only a 8 guage standard wire for stereo use, so I was curious.... But i know it needs an amp... Any suggestions? Here are some specs -10" satin anodized polypropylene cone -Extra wide surround for deep, clear bass -Inverted style dustcap -Mid-Q design for enclosure compatibility -Enclosure designs included -40 oz magnet -Sensitivity: 91dB -Nominal Impedance: 4 ohms -RMS power range: 150 watts to 450 watts maximum -Freq. Range: 22-200 Hz Anyone who could help PLEASE EMAIL ME!!! c3shukis@wmich.edu Or IM me on AIM as caleb12803 if I'm online! Thanks |

New member Username: BeanierPost Number: 3 Registered: Feb-06 | What I think most people are looking for is what do you do once you hook up a power supply? As in what color wires from your car stereo do you hook up to what color wires to the CPS? I'm somewhat technical, as I'm sure most people are who would want to do something like this, and I don't really understand fryguy's diagram. It's not laymans enough. It needs to be in plain english, with no summed current outputs or anything like that. And why is there a fan? This isn't car stereo specific, which is what I'm sure most people are looking for. There's lots of people wanting to do this, it would be awesome for someone to make a standard easy to follow page for this. Shoot, if someone can tell me how, I'll make a page about it. Needs to be cheap, homebrewed as possible(if people had the $, they wouldn't care about doing it in the first place) and in total laymans terms(if they were engineers, they wouldn't need to ask either). ;] |

New member Username: BeanierPost Number: 4 Registered: Feb-06 | And fryguy's diagram is good, just not car stereo specific. A page for this would need to be from beginning to end product for people to get it, I think. |
