Plug them all into a good clean power conditioner. You should have any good equipment going through a line conditioning device anyway. Besides the obvious benefit of common grounds, you can also filter cable (coax) noise in many of those devices. I use them in both my my home theaters and will swear by the benefits of clean power. (Plus you get surge control, etc). Also make sure your sub cable is properly shielded and not parallel to other signal or power wires. Good luck.
