I was stunned that amp in that price range could perform at that level. I used a couple of them in my install projects with both ceiling and on-wall speakers, it worked great in both cases. The DSP is also helpful, it gives you plenty of options to choose, from crossover, input sensitivity and input mode, limiter, etc.
Overall, great amp with plenty of power for good price. I didn't tried it with subwoofers yet, but for mid-high is definite recommendation.
