well i just have 1 monoblock amp for 2 12"subs and all the door speakers are connected straight to the head unit (Panasonic)all the wiring was done professionally but i recently took the amp out and when i put it back was when i got the problem. the reception is fine at low volume but as soon as i raise the volume, the static comes in pretty bad, the amp is powered by 8gauge power wiring from a distributor that has an input of 4gauge wire, ground wire is 8 gauge also

re-check your amp wiring.
this sounds like a bad ground.
also make sure your signal lines (RCA) are separated from teh power cables.
having them side by side can introduce noise.

This really just sounds like a wiring faux pas somewhere.
