sometimes there is an adjustment for this on certain amps (probably a small twisty nob)sorry for the strange description!
but as gouki says probably a dodgy earth.

are the phono leads away from the power?
idealy they should be on the opposite side of the car from eachother as they can interfere with eachother espesially when the engine is on and revving. You will hear a whine nosie that responds to you revving the car.

thats another possibility, if the RCA's are side by side with each other that can also cause the interference.

It may be the quality of your RCA leads or earthing/grounding problem, check both the amps and headunit.

I think you are all barking up the wrong tree.

It's electrical interference from the engine, I'd say you've most likely got a faulty surpressor (the device that prevents this interference).

Cheers,

Check your alternator for loose wiring
