Hey, thanks for the quick replies. I should add that my sub is hooked inline (proper term?) with my speakers. Speaker wires run from the amp to the sub and out to the speakers. Sub is a HSU VTF-something... can't remember the number off-hand. I also should add that my speaker wire is just the basic stuff. I thought quality of speaker wire was just a sound issue and I would never hear the difference so that's why I bought the basic wire. If I thought there was a possibility that cheap wire would cause equipment damage I would have certainly ponied up the extra $'s.

Yes, the amp gets super hot before it cuts out. Regardless, I'm hoping it's not the amp because I'm not sure where I could get it checked out. Don't know if this additional info helps out...
