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

    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.
