ive been putting music in my cars for years, but never to the point that im doing this car, so i know how to install and make it work but im going for loud spl. so i have some little questions here and there. my question here is what is better to use caps or batteries and what would i need to use in my setup. im going to be using 1 maybe 2 5500 watt amps and 1 2000 watt amp and my car has alot of lights so i want to make sure i have enought power but not over kill. thanks
