Hi, need help connecting pair of Mordaunt-Short Classic 20 Speakers to system. Have Sony STR-DH790 Receiver & Sony SA-W2500 Subwoofer. Also have center channel, two Polk S15 surround speakers & two old Kenwood surround speakers. Plan on running 7.1 Surround sound system for music and movies. Know very little about Technical stuff like crossover this and that, banana plugs, bi-connectors, bi-amps and all that stuff. But am willing to get whatever's needed to hook system up correctly so I can get some awesome sound. Need to know what brand and gauge speaker wire to get, what exactly banana plugs are and if I need them for these speakers, if I need bi-whatevers, how to connect them, etc. These speakers have two sets of speakers jacks. And they're the kind that you wrap the speaker wire around and screw the thing down to hold the wire in place. As you can see, I'm lost. Please help. Thank you very much. If you need pix lemme know.
