zaxfire69 Posted March 4, 2009 Report Share Posted March 4, 2009 I am running alot of pre amp voltage through my rca's. Not sure on the exact number, but My Headunit is a 5V Kenwood and I am running the old Phoenix Gold PLD-1 line Driver. Quote Link to comment Share on other sites More sharing options...
Cr@sh Posted March 4, 2009 Report Share Posted March 4, 2009 (edited) Well one of the goals of "Pre-amp" voltage being higher is less gain used on the amp to match it, also known as gain matching your input source. With less gain used the amps output is less likely to clip or become distorted (for those that don't know what clipping is) Edited March 4, 2009 by Cr@sh Quote My old install at cardomain, never finished!

SubSonic Posted March 4, 2009 Author Report Share Posted March 4, 2009 ok?? well i already new that but im saying, your chaging system put 14.4volts when your car is running from the aternator, i want to no how u r able to boost that to 16V, for such amps as the Soundstream 6500??? does u use a relay or what??

Cr@sh Posted March 4, 2009 Report Share Posted March 4, 2009 A custom alternator is one way or 16volt batterys is another. The dilemma is if you buy 16volt battery or batterys for the rear as an extra battery you cant charge it at 12volts from a stock alternator and hope it will work. The solution is get an alternator that will feed 16volt to your 16volt battery and put 12volt to the car using a regulator. Mechman makes them, or other companies.

The rule around here with 16/18v is that if you have to ask, you can't do it Quote 10.x volts fo' life! Link to comment Share on other sites More sharing options...
MickyMcD Posted March 5, 2009 Report Share Posted March 5, 2009 You need, as mentioned before I butted in, an alternator that produces 16v or 18v under load dedicated for audio, or a 16-18v alternator with step-down regulator for general use. However, and I mean this in the nicest way possible, stay away from whatever you are thinking. I am guessing you want lots of watts, but from what you've shown I think amplification like this is a bit out of your league. Again, I really don't mean to be offensive in any way, but this is how accidents happen. Sure, you'll learn after you've dumped 5kW into drivers that can't handle it or are not suitably baffled and destroy them, but you are using some very expensive gear here. What I am more concerned about it fire danger. These devices require lots of current, and wiring that is not safe or not rated for the current this device pulls can cause quite intense fires, let alone the same amount of current at a higher voltage. Let us not forget that a member here only had a small piece of sheet metal on the bottom of the car seat create a short circuit environment, and he lost everything. The car, the equipment... You need a solid amount of electrical knowledge before you start moving power like that around. Please research some basic electrical theorum before undertaking this project. Also, a relay is a voltage operated switch. It will have a switching voltage (actuator voltage) and a load rating. For example, when fed 1.5v 200mA the relay may open a 240v 10A switch.

stayfly33 Posted March 5, 2009 Report Share Posted March 5, 2009 i dont mean 2 jack this thread but i dont like starting new threads for just one question when is it a good idea to put another battery in your setup? i want to make sure i know everything i can before i start buying things and messing things up from the start. if i was running a hifonics 1608D should i get another battery?

Zade08 Posted March 5, 2009 Report Share Posted March 5, 2009 With that amount of power just buy a slightly larger stock battery and youl be fine. I would suggest the big 3 and maybe a new alt depending on your car. Quote Vehicle: 2001 Ford Escape Head Unit: Kenwood Kdc-x592 All out for a rebuild. New shit coming in the next 30 days.

stayfly33 Posted March 6, 2009 Report Share Posted March 6, 2009 iight thanks but when is the point where should get a new battery? i figured i would need one when running at least a 2000 watt amp Quote Bass is my drug.
