I did that, still nothing. But, I have adjusted the finer things in the channels, crossover, etc and my vintage speakers sound like I remembered them back in the late 70's. Before, they were very shallow and weak. Now, the woofers pump hard and the highs and mids are far crisper. I always kinda wanted to remove the sub from the system, seems like that day has come. Since the sub and everything worked prior to a recent move, I can only assume some sort of damage occured during the move.
I sincerely appreciate all the help to this point!
