Hey guys. I want to ask a question about subwoofer wiring in a non-5.1 system.

I have an older, Pro-Logic receiver (no "sub out"). And, I am getting a new powered subwoofer. The way I wired this in the past was to run a set of left and right wires from the "B" speaker-level outputs to the left and right speaker-level inputs on the sub. This way, if I didn't want the sub on, I could just turn off the "B" output.

I know that there are several ways to hook up a sub, and I'd like to hear some opinions on the subject. Pros & cons on different options.

Thanks,
Nick
