I just bought the Pioneer VSX-822-K RT. I previously had a home theater in a box from Samsung that included a sub-woofer. The problem I am having is that the Samsung subwoofer has a single speaker wire which connected it to the blu-ray/reciever. The Pioneer is looking for an RCA jack. I have seen suggestions that I can connect the wire from the subwoofer to the front speakers, but they all seem to imply that there are two wires coming out of the subwoofer. Can I just connect this to one of the two front speakers?
