A voltmeter cant check the ground - but if the noise stopped when you unplugged the RCAs you have already isolated the problem to either the headunit or the RCA cables themselves.
First, buy a new set of good quality RCAs. Run it on the opposite side of the car of the power cable and do not run parallel to the ground/power cable for more than 6 inches before it meets the amp.
