However, the situation I'm getting right now is that I'm either getting the system to only have sound coming out of the left, right, and subwoofers (A + B) or if it's a different mode, it'll only come out of the center channel speaker. Everything seems to be hooked up properly. Lastly, I have the two rear speakers in the surround sound section (rear) of inputs for the receiver. Center channel is plugged in and working properly. Right now, I have the left and right front speakers in the A setup, and the left/right inputs from the subwoofer going into the B setup. Either way, the HTR has A and B setups for the front two speakers. I just picked up an HTR-5960 over the weekend, and have a Polk Audio RM6750 system for the speakers (it's a 5.1 setup, might go to 7.1 eventually).
