If your equipment supports it then a balanced connection between the amp and sub would mean you wouldn't need to worry about ground loops at all and can plug in the sub wherever you want.
Should Subwoofer Be Plugged Into Same Circuit?
I am running electrical lines for my theater myself. Should I make the outlet for the sub on the same circuit as the rest of the AV equipment, or put it on a separate circuit?
i could have sworn I read something that said it needs to be on the same circuit to help prevent ground loops.
