I am having trouble with some electrical interference on my Subwoofer. I wired my electronic closet on a separate circuit, but my sub is plugged in to a different circuit. I am running it through a Panamax 5000 along with my TV. There is a noticeable noise coming through the sub and when I turn on a fluorescent light in a closet the sub thumps. I connected the sub to my receiver via CAT5 through the wall. Does anyone have any suggestions on how to easily rectify this issue?
