New member Username: Iceman600Miramar, Florida Usa Post Number: 4 Registered: Jan-08 | thanks for the response guys. question... why is the amp that i choose not good for my subs? it got 3000w of power compare to 1400 watts rms at 4 ohm bridged or 2 x 700 at 2 ohms stereo (true power) like what sean said. or the 2 x 230 into 4 ohms stereo or 500 watts rms into 8 ohms bridged. can someone pls explain to me the diffrence? and i thank you all for helping me. |

Gold Member Username: Tatonka-[Team Audib... Post Number: 1371 Registered: Mar-07 | The amp you picked out does not do 3000 at all. It is 3000watts PEAK power. You will not see that at all. Here are the real specs it lists: 800 watts @ 2 ohm * 550 watts @ 4 ohm * 300 watts @ 8 ohm |
|
New member Username: Iceman600Miramar, Florida Usa Post Number: 5 Registered: Jan-08 | sean i read some stuff about the amp you suggested... the Professional 500-Watt Reference-Class Studio Power Amplifier,the last one in you list. it says that it delivers 2 x 230 Watts into 4 Ohms or 500 Watts into 8 Ohms bridged. the spaker that i choose is 4 ohms with 600w rms. how can the amp deliver the power if the amp got only 230 w into 4 ohms. im confused. sorry for being stupid but i just wanna know the logic behind it. and besides this is a new learning experince for me. thank you again guys. |

Gold Member Username: Tatonka-[Team Audib... Post Number: 1372 Registered: Mar-07 | Your sub will only run at 2 ohms or 8 ohms unless you are running two of them. |

Silver Member Username: Snowball123West Allis, WI United States Post Number: 139 Registered: Oct-07 | that sub you put up is dual 4 ohm. so you put wire it to 2 ohms. |

Platinum Member Username: WingmanaliveA pic is worth 1000 posts!! Post Number: 12598 Registered: Jun-06 | I hate peak wattage ratings. |
|
New member Username: Iceman600Miramar, Florida Usa Post Number: 6 Registered: Jan-08 | pls explain more if you dnt mind? why is it that my speaker will only run at 2 or 8 ohms? and if it does still the amp that i choose will deliver the power right? and one more thing tho... the reference amp A500 that sean suggested, the one that delivers 2 x 230 Watts into 4 Ohms or 500 Watts into 8 Ohms bridged. can that brings out the power of my subs? |
|
Gold Member Username: InsearchofbassPost Number: 7578 Registered: Jun-04 | "can that brings out the power of my subs?" are you planning on running one or two subs?...im guessing you meant sub meaning one...if so that is a dual voice coil sub (dual 4 ohm) so you can only wire it to 2 ohms or 8 ohms The only draw back I can see with the A500 is it doesnt have subwoofer filtering at all but if your sub is tuned low enough that shouldnt be a problem...personally for 150 bucks for that sub id pick another brand that will sound better for your design goals |
|
New member Username: Iceman600Miramar, Florida Usa Post Number: 7 Registered: Jan-08 | thanks sean... well im planning one sub for the moment coz its just for my room. well maybe after i got this thing pumping the way i wanted i will do another one.(BIGGER ) so i'll be staying staying at the A500. coz i trust you man. and besides i dnt have any experince on this. so A500 will be great! and is a lot more cheaper! so now that i got my amp. what sub will you recomend? since you told me to pick another one. what brand will you recomend? |

Gold Member Username: InsearchofbassPost Number: 7579 Registered: Jun-04 | can you purchase from ebay or no? |
|
Gold Member Username: InsearchofbassPost Number: 7580 Registered: Jun-04 | if so this image dynamics 12 dual 4 ohm would do VERY well for home use it will hit low and serve you a long time if its not abused....I own a similar line by the company in a 12 like this one...dont let the cone size fool you it will perform http://cgi.ebay.com/12-ID-12D4-Image-Dynamics-Dual-4-Ohm-Subwoofer-ID12d4_W0QQit emZ180208146690QQihZ008QQcategoryZ18803QQssPageNameZWDVWQQrdZ1QQcmdZViewItem |

Gold Member Username: InsearchofbassPost Number: 7582 Registered: Jun-04 | its rated 400 rms but as long as you dont push the volume too much it will be fine |
|
Gold Member Username: InsearchofbassPost Number: 7583 Registered: Jun-04 | make sure you decide which way your going now because if your going to uprade later you might wanna spring for the larger amp i posted and save up more money for the subs |
|
New member Username: Iceman600Miramar, Florida Usa Post Number: 8 Registered: Jan-08 | yeah i can purchase on ebay... but i dnt know the brand man! is that good? im having second thoughts about your warning tho. "its rated 400 rms but as long as you dont push the volume too much it will be fine" and the rms of this is only 400 the cerwin-vega i choose have 600 rma. is 400 rma better than 600? |
|
Gold Member Username: InsearchofbassPost Number: 7584 Registered: Jun-04 | unless your just going to buy a second a500 with two image dynamics....youll just have too make sure you can get a second sub |
|
Gold Member Username: InsearchofbassPost Number: 7585 Registered: Jun-04 | ok how about this one from resonant enginnering the se 12 its a little over your buget but very much worth getting at 165.10 shipped 600 rms http://cgi.ebay.com/NEW-RE-AUDIO-SE12-12-CAR-STEREO-SUBWOOFER-1200W-WOOFER_W0QQi temZ270205221045QQihZ017QQcategoryZ18803QQssPageNameZWDVWQQrdZ1QQcmdZViewItem |

New member Username: Iceman600Miramar, Florida Usa Post Number: 10 Registered: Jan-08 | its good tho.. i like it... but is that actually the same as cerwin-vega? no dont get me wrong bout always asking but what is it that you dont like bout the cerwin -vega? i mean they got the same 600 rma right? and the cerwin-vega is 3" bigger.(bigger looks cool esp if im going single, right) and i've been planning to purchase the amp today but my girl told me to find a cheapper one. you know girls right... and i found this... http://www.musician.com/product/Gem-Sound-XP550-Stereo-Power-Amp?sku=481218&src= GWFRWXX&CAWELAID=28555945 it has "500W/ch RMS @ 4 ohms stereo" i think this is not enuf for the sub that i wanted right? just want your opinion. |
|
Gold Member Username: InsearchofbassPost Number: 7587 Registered: Jun-04 | im looking at the sound quality the strength of the build and the ability to play clean down low for music and movies too if you ever use it as a home theater sub...it will be better than the cerwin-vega overall ...that amp looks very cheap id steer clear |
|
Bronze Member Username: Iceman600Miramar, Florida Usa Post Number: 11 Registered: Jan-08 | ok... thanks for your help sean. tug you soon after i make this subs of mine pumping. maybe ill stick to what you've told me. i will get the one from resonant enginnering the se 12 and the A500 power amp. thaks again sean |

Bronze Member Username: Iceman600Miramar, Florida Usa Post Number: 12 Registered: Jan-08 | QUESTION... 1. if the delivered rma of the amp to the sub is lower than the rma of the sub, is that ok? 2. will it still produce great bass sound? (that chest punching sound i mean) example: a500 amp with a 2x230 watts on 4 ohm. with a sub with 600 rma 3. in the amp like the A500 with a feature of 2 x 230 in 4 ohms and 500 Watts into 8 ohms in bridged mono operation. a.) what does 2 x 230 in 4 ohms mean? b.) what does 500 watts into 8 ohms in bridge mono operation means? hope someone can explain this this to me... sorry guys, im just so intrested in knowing this kind of stuff. thank you }}} |
|
Gold Member Username: InsearchofbassPost Number: 7592 Registered: Jun-04 | ok 2 x 230 means 230 per channel in this case it means left and right (in stereo) true power readings are measured in rms..not rma like you called it ohms are the measure of resistance and in this case you using the a500 in bridged mode you want a 8 ohm load It is ok to use less power than the subwoofer is rated to handle but if its too low the sub may not perform to its full potential but a little less power isnt bad...over powering can be ok but the speaker must be used and set up properly |
|
Bronze Member Username: Iceman600Miramar, Florida Usa Post Number: 13 Registered: Jan-08 | ok... this is what i understand on what you have said... pls correct me if im wrong. ...if i will set up my sub i will go with the 8 ohms in bridge mono coz it supplies 500 watts and the sub can handle 600 right?! ...it is ok to put a low power amp than the subs can handle but if it is too low, subs will not work its full potential. ...overpowering the subs is bad.( like having 1000 rma amp hook up to a 600 rma subs.) am i right? sorry for being dumb |
|
Gold Member Username: InsearchofbassPost Number: 7593 Registered: Jun-04 | you are right |
|
Gold Member Username: InsearchofbassPost Number: 7594 Registered: Jun-04 | but realize bridging that amp makes it so you can only use it for the subwoofer....you would need a reciever to drive other speakers for the vocals etc |
|
Gold Member Username: InsearchofbassPost Number: 7595 Registered: Jun-04 | will this project of mine will work?! "and im planning to hook up the reciever to my pc so i can play tunes using winamp" ok im sorry based on this comment you made above we need to stop where were at.....you dont have a reciever by the sounds of it and the amp I showed you doesnt have a crossover built in so you would have to add one which costs more |
|
Bronze Member Username: Iceman600Miramar, Florida Usa Post Number: 14 Registered: Jan-08 | but realize bridging that amp makes it so you can only use it for the subwoofer....you would need a reciever to drive other speakers for the vocals etc im confuse again?! why do i need a reciever this time? ok here my original plan... i want to hook up a powerful sub into my pc. i know a reciever can be hooked up to a pc right? thats why its all started. thats why i picked the Technical Pro 3000W Digital Home Receiver to power the sub and hook it up to my pc. is that plan bad? i mean not good? should i purchase a reciever to hook up the A500 to it and hook the reciever to my pc dnt know what to do now... HELP!!! i want the subs!!! |
|
Bronze Member Username: Iceman600Miramar, Florida Usa Post Number: 15 Registered: Jan-08 | WAIT WAIT WAIT... I can produce a reciever. just to go to my parents and there is one their not using. its a pioneer. i can hook that up to my pc. now the only problem will be how to power up the sub and hook it up to the reciever. if the A500 is not applicable. what amp will be hooked up with the reciever. whoo.. i almost give up there... |
|
Gold Member Username: InsearchofbassPost Number: 7596 Registered: Jun-04 | you can do that with a home theater reciever and then add a subwoofer and amp and plug it into the subwoofer out .....and use it for movies and regular stereo use and later add the rest of the speakers for the complete surround sound effect for movies ....you can hook your pc up to this setup with the right cabling....I did this setup |
|
Bronze Member Username: Iceman600Miramar, Florida Usa Post Number: 16 Registered: Jan-08 | so still i can use the A500 amp? |
|
Gold Member Username: InsearchofbassPost Number: 7599 Registered: Jun-04 | using it as a subwoofer amp wouldnt be a good choice because it doesnt have an adjustable subwoofer crossover built in....i dont think any of those amps I mentioned have one...sorry I missed that |
|
Gold Member Username: InsearchofbassPost Number: 7600 Registered: Jun-04 | to make a long story short a passive crossover would be pretty much a pain thats why im recommending one built into the amplifier |
|
Gold Member Username: InsearchofbassPost Number: 7602 Registered: Jun-04 | im gonna sign off for the night ill try to check back another day soon |
|
Bronze Member Username: Iceman600Miramar, Florida Usa Post Number: 17 Registered: Jan-08 | thank for your help sean. since we've come this far if it is ok with you, can you pls give me a list to built my dream sounds. just want to have a power subs hook up to my pc just like in my car. thanks! |
