Hi, Guys! I need some help in order to not waste my money in vain. I bought a pair of Polk RC6s speakers. I intended to use them as surround speakers of a 5.1 home theater system, with a Pioneer VSX-51 Elite receiver. But I didn't know that they were made to be used lonely, instead a pair of speakers. Now I have to figure out a way to use this speakers with my receiver. They have a pair of +/- connectors, in order to produce stereo sound each one. Do you think it is possible to connect each speaker in a single channel (left or right) of my receiver? I was thinking of using just one pair of connectors of each speakers and leave the other one idle. There will be any damage? Otherwise, do you realize any way to connect each surround terminal of my receiver (left and right) in the two pair of connectors of each speakers in order to use the full power of the speaker? Thanks a lot.
