Oh yeah and I forgot to mention this dang buzzing I'm getting in all my speakers now, it is more pronounced in the center.

As soon as I plug the other subs, either daisy chained, or y-adapter at the receiver, buzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
