I think our home stereo is up so that the amplifier's speaker output 
goes to the subwoofer, then the subwoofer splits the output to each 
stereo speaker while filtering the highs out of the subwoofer signal and 
the lows out of the speaker outputs. Our receiver doesn't have a 
separate subwoofer output like newer ones do, I guess.
