i dont think its your H/U ground, maybe your ground to your highs/mid amp. Try making a better ground to the amp. Or maybe upgrade your big three to get rid of some noise also.

To answer your question yes, you can ground it directly to the negative terminal on the battery. It may help your whine problem.

You could try grounding the negative shielding on the RCA to the same spot as the HU, just take a thin bit of wire and solder it to the outer prongs then go to the amp and do the same thing with the other side of the RCA cable by grounding it to the same spot as the amp.

That should kill off any ground loops.

the negative post of your battery connects to the chassis of your vehicle. therefore, grounding it to any part of the chassis will be just the same.
