I am starting to wire up my multi-room audio system (russound with yamaha speakers) and think I may have made a mistake on a couple of speakers. I wired my bathrooms with two runs of speaker wire so that I can have stereo sound out of one speaker. For the bathrooms I purchased yamaha ns-iw280c speakers thinking they would do the trick. But when opening the box I see the speakers have only one set of wire connectors. Would I hook up the both positive wires (left and right) to the positive wire connector on the speaker and same on negative and get surround out of the one speaker or do I have to start shopping for other stereo speakers with a left and a right connection on them?
