Re: bad ground?
Some call it motor boating and it's caused by a high resistance in the power supply wires, ground or B+. Check at the battery, fuse holder, and ground.

Re: bad ground?
either the rcas are bad or your getting road noise.. did you run your rcas on the same side of the car as your power wire?
