I have a problem with my system i just installed subs and an amp and it sounds great so i got a new deck hook it up it all worked and sounded good for a couple weeks then every time i turn on my system my subs thump out of control with the volume all the way down, but when i re hook up my old deck it doesnt do that just recently now my old one does it, im really frustrated i cant figure out what it is?
check the ground on the cd player, dont hook it up to the factory harness ground, hook the ground to the cd player directly to some metal behind the cd player. (drill with a ground screw)
