I would suggest bad ground on your amp or deck, or what rdkjrss said power needs to be on oposite side of the rca cables.... and im sure someone on here is gonna say that it sould have been posted in the alt section....

I dident hook any of it up. I got it professionally installed so I am gonna go back there tomorrow to see about it. The guy said I would just need to upgrade my alternator because I havent done it yet. My setup is taking a lot of power.

Misread the post, sounds like it could be a bad ground, or diode.

Is it coming through the speakers or from the alt?
