    Nice little amp, I love that the bench test papers come with it. It powers my older JL 4 ohm 12s perfectly.

    Paired with a Kicker subwoofer and it sounds amazing. Easy to use and setup. It's lightweight and compact. Easy to mount. Great build quality.

    So far, so good. Works as expected. It is powering a a CompRT 8 shallow mount subwoofer with passive radiator. In my opinion, the selection of low on the input level switch should output more that it does. On low, it seems to barely put out anything.

    The the continuous sound that this amplifier gives  really works for any sub that you can think of especially if you’re not looking to get too much bass. Any of the kicker amplifier’s will work as long as you make sure that you get the right wattage for the sub that you were wanting otherwise you’ll definitely under power which isn’t a bad thing.

    Really decent little amp. I use it to power 2 10” kicker subs and it sounds great. Big things really do come in small packages. The size of this amp was a nice change compared to the big bulky amps in used to.
