If you're using the stereo wiring in the dash, disconnect that and run a new one to the amplifier(s) and connect it to the amp's ground terminal or if you have a distribution block, connect it to that. If you were to measure teh resistance from the ground wire that's being used for the head unit and and amp, you would probably see a few Ohms and that's more than enough to cause a ground loop and this noise.
