    I own 2 of these amps, and I absolutely love them! Their power exceeded the ratings, which is always great. They actually ended up overpowering my 1000 watt rms subs. But I’m not mad, that just gives me an excuse to get new subs 😉

    Very good value exceeds ratings

    Have it hooked up to a HDS2.1 12″ and barely have the gain set to a quarter with my volume at about 75% and it clips?? I literally have to turn it down so much it barely even hits for it not to clip.
