I just bought a new Klipsch sub woofer today, I went to set it up and realized my receiver only has RCA out for subs. Do I need the special Sub woofer branded RCA or will any decent quality RCA cable do? Looking forward to watching 300 with surround and my new sub tonight....

RCA cables will do the trick...enjoy the movie:)

thanks! I got it working with a regular monster rca cable but it seems a little quiet. i tried adjusting within the receiver and on the back and there isn't too much headroom. Would the specific sub woofer cable give me any more volume?
