I was also wondering. My subwoofer has an white/red line in ports. i plug the audio cable white/red into the line in port. the other end of the audio cable into the receiver. i was looking for an subwoofer port on the receiver..but i only saw an red port that was label "subwoofer" i plug the red into it.. What do i do w/ the white? do i just plug it into the white port above it? but it doesn't label subwoofer.
Top right audio ports
Front, Center, Surround, Back Surround.
Subwoofer red point is under the Center.. what to do w/ the white?
