I have a HTIB that i was using in my bedroom. I've moved the receiver/dvd player to another room, but would still like to use the speakers with a standalone receiver. My main home theater is another room and I really didn't want to invest in another set of expensive speakers. My subwoofer only has speaker wire and not the regular sub cable. How would I go about hooking it up to my receiver (Kenwood VR209)? Or do I have to buy a new sub?
