I guess anything is possible but doubt it. I think it's most likely that I buggered the set up. I was in a rush the last day I was there and I'm going back Thursday to finish up. Worst case scenario is that I can't get it to work and I use the left and right RCA pre-outs to feed the sub.
My wife says I can't do sarcasm. She says I just sound like an a$$hole.
