When I spoke to the guys at CI, they confirmed that there is a maximum draw per plug on XDC-2. I don't know whether you can do what you propose, but the CI guys can tell you very quickly I am sure. I think in the traditional configuration the max draw per plug is 7 amps - but they can also build the XDC in parallel (??? forgive my lack of tech knowledge) which means as long as the total draw on both plugs does not exceed 14 amps then all is well. That's the way they built mine, at no extra charge, and I have a 500 watt/channel Musician amp and a 450 watt subwoofer amp drawing on the unit without trouble.
