Comments on: Is it possible to hook up a 3,000 Watt aftermarket sound system to a stock 1990 Chevy audio system? http://incaraudiosystems.com/is-it-possible-to-hook-up-a-3000-watt-aftermarket-sound-system-to-a-stock-1990-chevy-audio-system Mon, 21 May 2012 02:00:50 +0000 http://wordpress.org/?v=2.7.1 hourly 1 By: sparky3489 http://incaraudiosystems.com/is-it-possible-to-hook-up-a-3000-watt-aftermarket-sound-system-to-a-stock-1990-chevy-audio-system/comment-page-1#comment-3991 sparky3489 Fri, 20 Aug 2010 14:28:04 +0000 http://incaraudiosystems.com/is-it-possible-to-hook-up-a-3000-watt-aftermarket-sound-system-to-a-stock-1990-chevy-audio-system#comment-3991 You will need a LOC (Line-Out Converter) to convert the high-level speaker signal to low-level RCA signal to the amp(s). If your total system power is 1200 watts RMS or more, you will need to: 1. Upgrade the alternator to a high output alternator 2. Upgrade to a yellow top battery 3. Install the "Big 3" with at least 2 AWG wire. Failure to do this will result in the early death of the alternator as it will eventually fail. Here is a guide that will calculate what size alternator and power wires you need http://www.box.net/shared/uchv4dbk88 You will need Microsoft Excel. If you don't have Excel, use this link http://www.box.net/shared/nkkw1dhk4g A second battery is never a good idea as it's an added strain on the alternator to charge two batteries AND supply power for the car. The ONLY time a second battery is useful is if the audio system is to be used with the car off. A capacitor is only good so far as the audio system isn't trying to pull too much from the electrical system. A cap doesn't provide more power, it's designed to 'stiffen' the voltage to the amp, nothing else. If the current isn't there, a cap won't help. The alternator must have at least 20% more amperage power than the entire vehicle and sound system combined for a cap to be of benefit which is ironically the same requirements for an amp to be efficient.
