Excellent amplifier! Plenty of power to drive my 12in passive Polk Audio Sub. I had a couple of issues that I had to get ironed out and the customer service was great! I would definitely recommend.

Purchased the 300W version to work with my 7.1 home theater surround sound setup, to power my two 10” in-wall subwoofer speakers, easy to use controls the power, volume and crossover. I was very impressed with the power output and building quality. Nice clean modern look, auto on and off, low heat class d design, 12V tigger, speaker level and rca/lef In, everything I need in this unit, I have nothing to complain and very happy with the result, highly recommended.
