I recall the test sheet on my amp rated all four channels at a minimum of 140 watts at 2 ohms @ 1% THD.

The amp is 400 watts. The birthsheet that comes with each unit is the factory output test result for that specific unit. They areca little underated, but not an issue. As mentioned previously, if you use speaker level inputs they will get louder than low level input. The amp is a very good unit if 100 watts per channel, or the 200 watts bridged fits your overall build design.
