I am putting a couple of Klipsch AWR-650-SM speakers around my pool, and wiring them to a Sonos AMP (the new one). I notice the wiring coming out of the speaker is 4 conductor wire, and the Sonos AMP has 2 banana plugs. The wire distance to one speaker is about 120ft, and the other speaker is about 150ft. I plan to purchase direct burial speaker wire.\n\nHere are my questions: \nIs 12AWG wiring sufficient or should I go with 10AWG wire?\nDo I need 4 conductor wire? Or can I do 2 conductor wire and wire the 2 positives from the speaker to the positive on the wire run? and then do the same for the negative wires.
