you probably have the wire running next to a power wire. try re running the wire another route away from other cables.

You have a ground loop. If your amps are grounded at one common spot, try grounding the shields of the rca's as well and see if this solves the problem. You can also connect the head unit ground to the amp ground with a jumper.

You can buy a ground loop isolator for about $10-$15 most anywhere car audio is sold

Dont buy something else to hide the problem. find the ground loop and fix it. A ground loop isolator is always a last resort and they dont always work.
