Powerful, clean booms. Powers my OEM 2x 8" shallow subs rated at 4ohm 70watt each. Need to keep the subwoofer level knob near minimum. Lots of little knobs on the amp. Had to get a little allen wrench to remove the metal covering above the terminals to get access to the screws.
The unit runs very hot, so hot it hurts your fingers if you hold onto it for more than 2 seconds. The unit stopped working one time, just had to restart the vehicle to get it to work again. Not sure about that, whether caused by heat issue or not. But I do like the performance. Only had for one day, hope it lasts.
