Yeah, I already put the gangbox in, I'm sure the speakers will cover those too...they're 9 inches wide, I'll mount them such that they conceal the gangboxes...thanks for your input. My other option is to get the mounting brackets and just leave terminal plates on the walls. I decided on the gangboxes mostly because I wanted a big enough to hole to reach my hand into when I was fish the wires up from my basement....which actually wasn't that hard. I didn't have to cut any large sections of drywall outta the wall like I thought I would have to do.
