the problem is in a ground somewhere. check the amp ground first, then the head unit ground. Move the headunit ground to a chassis ground instead of in the harness for good measure. next check the RCA's. first wiggle them and try to recreate the noise. If nothing try this;

take a small guage wire and touch it to the outter edge of the rca jack behind the headunit. the outter metal part where it plugs in. touch one end of the wire to the rca and the other to the metal part of your deck. You may have a bad RCA ground in your deck. if you do this peice of wire will fix it.
