How do I increase the volts to the amplifier
|
Bronze Member Username: Jay_boyRochester, NY Usa Post Number: 35 Registered: Feb-10 | Many of you are familiar with my ignorance. I have jl HD 750/1 running 2 8w7s sealed. I want to continue to use my stock HU. I plan next week to put in a MTX RE Q so that the bass will not diminish when the vol. in increased. (unless I get adverse feedback) Now that they are broken in and I face them to the rear of the trunk, they sound much better. How do I increase the volts?????? I "believe" that the volts are low (amp is sometimes hot) Inc. in volts would be better for the amp and also increase the RMS output. (from what I've read) Also, where does the amplifier get the volts? Is it from the HU, battery, alternator or combination thereof? Should I get another battery for run them in series? Upgrading the alternator is going to be expensive and I don't think it is necessary but I don't know what to do so please advise |

Just shoot for ~13.8-14.4v and try and stay there. |

If your amp is getting hot make sure its in a place where it isnt covered and make sure the gain isnt set too high. One cheap fix to help stablize voltage is going to be upgrading the big 3. You're not going to get any more power out of your current amp if you some how increased the voltage. It may run cooler but thats about it. Upgrading your alt shouldn't be neccesary with 750 rms. |

A regulated power supply amplifier will not produce any more power with higher input voltage. |

Bronze Member Username: Jay_boyRochester, NY Usa Post Number: 36 Registered: Feb-10 | Isn't it the volts from the Stock HU that may not be enough? Doesn't aftermarket HUs produce more volts? Therefore, the stock HU is not going to give enough "volts"? also, my lights dim when the amp is pumping bass. Alt I believe is 75 amps. I will try the big 3 upgrade first. I would like clarification on the above situation please. |

Silver Member Username: Gcs8Atlanta, Ga Post Number: 286 Registered: Sep-09 | Well if you are using a live converter (speaker wire in (boxish thing) rca cables out) so that could be just as easy as turning a knob on that (if u break something I am not liable) but that would give your amp more voltage from the rca's. |

Silver Member Username: Simple_smithLapeer, Michigan United States Post Number: 319 Registered: Dec-08 | Try big 3. Line driver possibly? Upgrade to Aftermarket Head Unit. Upgrade your stock battery. What vehicle is this? What gauge power wire? And M.S. is right, the only thing you will accomplish by doing all this will be making your amp run cooler. |

|
Bronze Member Username: Jay_boyRochester, NY Usa Post Number: 38 Registered: Feb-10 | OK. Riddle me this you audio Gurus. What is the difference between the volts that the alternator/battery supplies to the amp and the volts the HU supplies to the amp? If you are guessing, say so. |

Bronze Member Username: Jay_boyRochester, NY Usa Post Number: 41 Registered: Feb-10 | OK. My stock HU doesn't put out enough power to the amplifier, therefore I am going to put in an MTX REQ5 and a line driver. Does it matter which line driver? Audiopipe has a mulit driver for $20 that inc 12db, others have bass boost (does this matter?), and yet another is only $13 and yet another that says it increases by 18db. Does it make much difference which I use? Perhaps the multi is best because I plan to add another amp later for door speakers. |

Bronze Member Username: Jay_boyRochester, NY Usa Post Number: 42 Registered: Feb-10 | I found a line driver PAC-LD 10 that boost the signal 10x and puts out up to 10 volts!! All others say 4 volts. This one is $25.99. Is 10v harmful? Good? Bueller? Bueller? lol |

Bronze Member Username: Jay_boyRochester, NY Usa Post Number: 43 Registered: Feb-10 | OK. I get it. Thanks. Delmar, you have really upset some people w/your comments. I thought I wrote some ignorant things but guess you are the KING. lol However, I did see a phoenix gold 2 channel (don't know what they mean by 2 channel, please clarify) 8 volt. It is $30. Seems like the best one, however, maybe just the best ad. IDK so please give me some feedback on the line driver situation. |

Bronze Member Username: DelmerdearlsmithDirty South, Of Confusion US of A Post Number: 24 Registered: Mar-10 | They just mad cause they don't know what they are talking about...but this is the way to go...It will charge off your stock alternator but feed your amp 16v's instead of 12v's increased voltage means increased power...if this link works you can see what I'm talking about..if not copy and paste it.....A lot of my friends with big systems do this and its a noticeable gain..... http://www.batterycentralmall.com/Batteries/Kinetik_Racing-Battery/KR2416.html |

Silver Member Username: Gcs8Atlanta, Ga Post Number: 287 Registered: Sep-09 | only one problem his amp wont do any thing with extra power and you need a new altanator to charge at ~17v-18v to charge the 16v system so the only thing this does is give him a new battery, at witch point just get a 90-110ah battery and be done with it. really all you need is a battery and an after market head unit (a niceish one) and it will save you a lot of head acks. |

Bronze Member Username: Jay_boyRochester, NY Usa Post Number: 44 Registered: Feb-10 | I can't change the HU (personal reasons). Therefore I'm putting in the mtx req5 (cure the bass cutoff issue) and a line charger (cure the lack of volts issue). Please try to help me out here. 1) a) IS THE LINE CHARGER GOING TO GIVE ME THE EXTRA VOLTS THAT THE STOCK HU IS MISSING, THUS MORE PERFORMANCE? 1) b) IS THE PHOENIX GOLD LINE CHARGER (8 VOLTS) GOING TO WORK WELL? 2) ADDITIONALLY, IF I GO WITH THE BIG 3 UPGRADE, WILL IT HELP THE DIMMING OF THE LIGHTS? 3) MOST IMPORTANTLY, IS ANYTHING I AM DOING OR FAILING TO DO GOING TO CAUSE DAMAGE TO MY SYSTEM?????? Let's hear it guys!!!!!!!! |

Bronze Member Username: Jay_boyRochester, NY Usa Post Number: 45 Registered: Feb-10 | I still don't understand the difference between volts from the HU and volts from the alt/battery. Do any of you? |

Silver Member Username: Gcs8Atlanta, Ga Post Number: 288 Registered: Sep-09 | volts from the battery and alt it what power the amp and makes every thing run, volts (singnal) from the HU is what is used to rep produce the sound, think of it as the save thing as the red and white plugs on a a\v coard fro a ps2 or dvd player all it does is transfer sound, think of the volts on that line as vol the higher the volts the more vol you will get, if you give your amp more voltage on the audio input you will haft to adjust your gain on the amp, now the voltage from the battery and alt is like the battery in a remote controlled car when its all charged up the car goes fast (proper voltage) the lower the battery gets the slower it goes (inproper voltage). so think of it like this when you arnt bumping your system hard you hafe a charged battery, when you are bumping hardish you are now on a low battery beacouse your alt is chargeing your battery witch is a reserve of power for when your alt cant supply enof power, so like the retard's idea of a 16v battery wouldent do you any good becides the fact that your alt will only charge a 12v system, (it takes 13.8-14.4 volts to charge a 12v system.) so his idea is useless. boddem line eather turn down the system,s bass or get an high out put alt that will fix your voltage problem and dimming lights. the big 3 will help ciruclate power throw the car beacouse the cars body is the groung for the chargeing system and then allow more power to flow from the alt to the battery to charge, so the big 3 is a good idea if you are adding any extra load on the cars chargeing system. |

Silver Member Username: Gcs8Atlanta, Ga Post Number: 289 Registered: Sep-09 | it sounds like hes just some tard that hangs around people that probly know what they are doing and he thinks he knows what he is doing. hes the definition of how a bad contractor thinks. |
|
Bronze Member Username: Jay_boyRochester, NY Usa Post Number: 46 Registered: Feb-10 | Thanks Charles. According to what you said, the line charger will help the situation, big 3 and of course the reQ. Right? |
|
Silver Member Username: SkdooleyRoanoke, VA Usa Post Number: 361 Registered: Oct-09 | If not getting enough signal from your stock HU is the issue just get a new one.. It'd be simpilar and save you a lot of hassle. |
|
Silver Member Username: Simple_smithLapeer, Michigan United States Post Number: 342 Registered: Dec-08 | that would definitely be better, but he has already said he didn't want to get an aftermarket HU. idk why........... |

Silver Member Username: Gcs8Atlanta, Ga Post Number: 291 Registered: Sep-09 | probly saw a really ugly after market job and is afraid of how it will look, i got a great dash kit that matched my factory paint and all that bla bla 2010 brand new and the stock system lasted 6 days before i gutted it, never regretted it. |

Silver Member Username: Gcs8Atlanta, Ga Post Number: 293 Registered: Sep-09 | well they make boxes that let you use stearing wheel controllers i use one in my car. works fine. they make head units with xm in them and probly better interfaces then what you are using and tell your wife to stfu, my girl never wanted anything in her car, then i gave her a full setup and she fell in love with it. they don't know what they want tell they have it. http://www.dealercostcaraudio.com/pioneeravh-p4100dvd.aspx?gclid=CLS1hJyOrKACFct x5QodH3XAaQ http://www.pioneerelectronics.com/PUSA/Products/CarAudioVideo/In-Dash/DVD-Receiv ers/AVH-P4200DVD it has the ability to do xm and should also have the ability for HD radio as well, she should like that to. |
