not entirely related to this thread but the same thing happened to me last night while I tried to watch finding nemo. I'm getting tired of this problem and seems like it's going continue to show up in the future. So I think I'm gonna be force to finally put in a rear center surround speaker. My question is my front, center, and side rear speakers are all rated at 8ohms. In the outlaw manual it states if I want to add 2 rear center speakers chained together I should change the ohm setting on the 1050 to 4ohms. Will this have any negative effect on my other speakers since they are all rated at 8ohms. What's the difference between 8ohms and 4? Thanks in advance to everyone.
