when you say Ground loop, should I try using another outlet? Come to think of it you may be right, because the sub was working last night although, I wasn't to happy with the how little thump it was giving me, then I moved it to a new spot and changed sockets. I'm going to try it out and see what I come up with.

Can I use an extension cord/power bar or can that have a negative effect on the sub's output? I like where it is right now and will have to use one if I want to change outlets
