if i hook rca's up to the amp then plug it in 2 my laptop it doesnt do it like that only when its hooked up the cd player.

Answer
Hi Cody,

It definitely sounds like there's a problem with the head unit.  I'm curious whether you're hearing the actual audio signal, at a high level, or just random noise; but either way it sounds like your deck's RCA output has a problem.  If the head unit has more than one set of RCA jacks, you can try switching to a different set; if that doesn't work, you'll either need to use a line-output converter, and connect it to the speaker outputs to get an audio signal to the amp, or you'll need to repair or replace the head unit.

Hope this helps!
