Is it all speakers in the car? Have you checked to be sure the actual speakers themselves are not grounding out?

i have checked to see if the speakers are grounding it this just started when i put the 4 ch in on my old 4 ch it never did this i have exchanded the amp twice and it is still there and on the grounds i have removed all paint and used proper connections

have acess to a completely different 4 channel? try it, if the noise goes away, might be time to look into a different amp

lets see if it's the 4 channel itself do like never said if you have another amp available change it out see if the noise is still there if it is then they may illminate the amp. now we see if it's the rca's. run a different source right at the amp itself, like a portable mp3 player with a 3.5 to rca adaptor. that way we'll know if it's the deck, rca or in that area. if the noise is still there run a different power supply to the amp and see if the noise goes away then.
