    Just got a new 7.2 receiver and am hooking it up to an older Polk subwoofer. The receiver has 2 subwoofer RCA outputs (monaural) and the subwoofer has a left and right RCA line input (it also has speaker level inputs/outputs but I don't want to use these). Can I use just one RCA cable to either of the left or right RCA inputs on the subwoofer? Or do I need to run 2 cables-- one from each of the subwoofer outs on the receiver to left and right inputs on the subwoofer. Or do I need an RCA Y adapter single male to double male? Thanks for any guidance.

    Hook up one on each end. The subwoofer sums the R/L to mono anyway.
