OK first we don't know his intended use and load impedance of it. If bridging gives double the power that's a whopping plus 3 dB. Third when bridging you take the stereo minimum load impedance and double it. So if he has an amp that has a minimum load of four ohms in stereo that means eight bridged so if he has say a four ohm sub or dual VC eight ohm sub no go. But we dont know because he didnt say. 3db big deal. I assume a sub since he's inquiring about running one amp mono. Therefore my statement stands. I've sold plenty of both car and home audio bridgeable amps as a dealer. People delude themselves when they see a number twice as large.......which means 3db but often less stability too. Almost never is not never.

Bridging doubles the voltage which gets us 6dB more, and that is quite a lot.

  The NAD 2200 that he mentioned is 100 per channel or 200 Watts total. It can handle loads only as low as four ohms in stereo.
  
  When bridged it is 400 Watts total or twice the 200 when stereo. That's a 3db difference in total power. It can also only drive a load as low as eight ohms when bridged. It will run hotter bridged.
  
  We have no idea what the connection scenario is because the OP didn't say. A sub? Teo subs? Single or dual VC? Mono center channel?
