So I have a dolby digital receiver, and I thought I could hook up my logitech z640's to it, but this doesn't look like the best idea. I want to use the speakers to watch tv and DVD's in surround. I was initially planning on just stripping the cable on all of the satellites and putting them into the receiver like they were normal speakers, but I think they might be overpowered and FRY. Also, the subwoofer and center channel connection isn't exactly easy, as it's integrated into the logitech's amp system. Any ideas? I don't really want to buy new speakers.
