Hi all. I dont know to much about all this but have a question. Recently I got a HTIB from a friend with everything except the receiver. It was all brand new and never used. Only the receiver was not part of the gift as the original owner is using it for something else. Anyways I ordered a cheap used receiver on ebay for it and it came today. I did not realize that the subwoofer is passive and just has like two speaker wires coming out of it. In any event the receiver only has like an RCA jack for a subwoofer connection and no place to hook up this passive subwoofer. I noticed that the receiver does have a "Front B" hookup though for additional front speaker wires. Would it be possible to hook the passive subwoofer up to that and get good results? Or am I just out of luck? I dont really want to spend a ton of money and get an active sub unless there is no other way around it. Anyways thanks for any advice or ideas!
