I actually disagree with both of the above posts on how to hook up the sub. I used to use an old Toshiba receiver (2 channel, weighed a ton, supported -- physically -- my 27" TV without a problem), and I'd run the subwoofer off of one of the tape outputs (if you have multiple and they are not in use. Any output that is not cut out when you switch channels on the reciever will work. The sound is also better, IMHO. You would need a standard RCA-RCA L/R cable.
