I have a Yamaha DSP-AZ2 AV Amplifier (from Japan) which has a 130W Center Channel speaker terminal. It also has a Rear Channel speaker terminal as well. I have a Klipsch Snyergy Series C-7 Center Speaker which rocks and I have a Bose center speaker (VCS-10) that I want to connect in order to bring out the 6.1 sound. My problem is that I can't get the rear channel to work no matter what configuration I try to setup the AV Recv'er. So my question is can I connect the 2 said speakers to the one center channel terminal without damaging anything? Am I running a risk to something? I've tried it briefly and it works, but just not sure? Help!
