did you fart dude?
ground is on top of the trunk? you need to make sure the ground is in a clean bare metal spot, preferably to the chassis and tight!
as for the mp3 player get a headphone to rca adapter ( walmart/radio shack for a few bux ) and plug it directly into the amp and see if the problem is still apparent.
if the problem goes away you have a bad or shorting RCA cable. if it does not go away it may just be your ground... do that and let us know...
