I have the BPS 150 sub woofer. I have had it unplugged for a number of years because it is blown. Are they worth fixing?? I have a single RCA cable that I unplugged , where does that get plugged in?? I looked thru the manual and did not see any connection illustrations. Please e mail me at apd421@aol.com, or phone 508 367 1288, thank you, Anthony DeJon
