Hi there, according to other posts here, the 2 rear channels in the Denon is wired in series internally. So you can just hook up 2 speakers to each channel and they would be in series. Can I instead of running 2 seperate cables for each channel from the receiver, just run 1 cable from the receiver and just bridge them in series at the speakers. It would certainly save me a lot of cable? If I can then do I use the L or R channel, or the + from L and - from R ? Also when using 2 rear speakers how high should they be and how far apart? The Dolby site does not cover rear speakers. My surrounds are on the side wall, either side of the listening area.
