Does anyone have the specifications on this amp? I know that it is an old model from PPI, but would like to know if unit is 2 ohm stable in bridge configuration and how many watts does this produce.

Your best bet is to send PPI an e-mail or see if they have a archive on their site @ www.precisionpower.com

50x2 into 4 ohms stereo
100x2 into 2 ohms stereo
200x2 into 1 ohm stereo
200x1 into 4 ohms mono
400x1 into 2 ohms mono.

The ProMos-50 was one of PPI's "cheater amps".  They were 2-Ohm mono stable back when not many amps were.  Also, they flat-out underrated the amp.  Lots of guys used to compete in the 51-100 watt class, using one of these amps and a passive crossover network to drive all their speakers.  Pretty impressive for a "100-watt" amp.
