How can I hook up a non-powered subwoofer to the 3802? One idea I had was to use the the 2nd zone to drive it. This should work as long as I can select the the same source for zone 1 and zone 2. I would also turn-off bass management so the low notes would not all be directed to the subwoofer pre-amp outputs. Assuming zone 2 would give me a "stereo" image of the the source on 2 channels, it should work, right?
