The subwoofer is not stereo. It has one set of binding posts where I connected the two speaker wires from the ADCOM. I suspect this may have something to do with this or perhaps with the Y-connector being "balanced". Regardless though, I may avoid all of this if I used a single input from the RSX-1065 to a single input of the ADCOM and finally a single speaker wire to my mono sub. This avoid the Y-connector and the "biwiring" to the single binding psots of the sub. I am just concerned that running one channel of the amp may damage it. Any thooughts ?
Thanks
