Answer 1

If filtering the power supply etc. has not worked, look hard at the INPUT side of the amp. Noise gets in there much more easily. Try just disconnecting the player/ radio whatever, put a short on the input(s) (wire joining the live connection to the earth), run the car amp power on and see if any noise.

You don't have unshielded RCA's there, do you??

man usually when you use cheap rcas thats really the prob are your rcas shielded?? or are they those regular orange looking ones with the big red and black ends? when ever im at work and that happens we change the rcas to the high dollar ones and yeah that eliminates all the engine noise...
