    Lots of power in a small package. Got a great deal on sale + a Kicker promotion. Also had it installed by BestBuy. Currently only have 1 10" CompC sub running off it, but I know it can handle more.

    Very powerful amplifier. You get very good bass out of this. The only thing I didn’t like is that it didn’t come with a bad knob.

    Great value and quality! Had this installed with a 10 inch enclosed kicker subwoofer for over a year now... I set it once and basically forget about it. Added a remote switch to make life easier. Not once has it let me down, i definitely recommend this amplifier!
