*Sound Experts Needed* - Noisy Audio

My carPC setup seems to be very noisy, particularly when the PC is booting up and before Windows comes online. There is a high-pitch whine in the background and I can hear my HDD accessing through the speakers.

When Windows comes online the noise diminishes, but it is still present. I'm assuming this is a grounding problem (my amplifier is in the trunk and my carPC is toward the front of the car).

Using a voltmeter I have determined that there is a small voltage (~1-2 volts) between the grounds of my RCA cables and a grounding point at the front of the car.

My question is: If I short the grounds of my RCA cables to the grounding point up front, with this help to eliminate some of my noise?
