A 2-channel amp in bridge mode is not exactly still equal to a true monoblock, but is a cost effective alternative to getting more power to the speakers. You will also want to check your OHm rating on your speakers before getting ahead of yourself. The Parasound HaloA23 that I mentioned can do 200w/channel in stereo @ 4 ohms, but can do 400w/channel in bridged mode @ 8ohms. Just something to consider. The Parasound Halo JC1 monoblock destroys those numbers those.
