Sounds like a bad earth. Check all your connections, and make sure you have a good earth on all.

If you haven't already done so, it also helps if you take power and speaker wires down seperate sides of the car.

sounds like a floating earth problem between the amp and phonos. A way to check is to get a length of speaker cable about 6 inches long and earth it out to the amp and the outer metal casing of the phono the noise should then go . Had simular problems in the past
