    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!

    The Kicker 800W amp is a powerhouse that delivers impressive performance. Its robust design and build quality ensure reliability and longevity. The amplifier’s output power provides a significant boost to the audio system, delivering crisp and clear sound across various frequencies. Installation is relatively straightforward, and the amp’s versatility allows it to complement different speaker setups. However, for some, the size of the amp might pose a challenge when fitting it into tight spaces.
