NAD 2200PE bridging question- need help.

A while back I was asking for amplifier suggestions for a pair of Carver Amazing Loudspeakers. Since I already had a NAD 2200pe I decided to pick up another one and I am going to bridge them. The problem is that I do not have an owner's manual. Some amps have a bridging diagram on the back so you know which speaker polarity will serve as the positive and which will be negative. From what I can see on the back of my NADs the two positive speaker terminals will be used in bridged mode but which will act as the negative for the one speaker it will be connected to. Also, which input (left or right) will I need to use for the interconnects. I guess I could experiment with different connection options but I was hoping someone out there would already know or have a similar setup. Thanks in advance.

(i am watching for the answer as well - i plan to use my NAD Amp bridged mono to drive a 15" sub...)
