are they the amps with the crossover cards? they say dsm or tans ana on them? if they are then i hear that those were very good amps and very under rated....
if its one of the all black bar b que grill style then you can expect at least 500 watts at 2 ohms....but they were very underrated....I have one of those style amps but its the 4 channel model which is the 4080....I bridged a pair of channels to a sub and they bumped my sub harder than a 600 watt amp that i had to it. The only thing about it was that my other amp had more controls to make my sound a little better. If you have an eq you should be very hapy with the 200
