    This little amp surprised me. I really like the DSP to fill in the lost frequencies of the lower end from my stock system.

    This amp is powering a JL 10” at 4 ohms with no issues. I was able to use the gain setup but struggled with the DSP.

    I purchased a kicker amp for my vehicle and it improved the stock sound dramatically. So when i added a subwoofer, i wanted to stick with Kicker. I have not been disappointed. Easy setup, using the white noise downloaded from Kicker website. Very pleased with the product.

    If I could give it zero stars. I would. Impossible to set up without taking it to a "professional" 0/10 wpuld reccomend. Its already a bad design that easily overheats. On top of the key comluter system that makes the amp impossible to set up. Its veen over two months and I still cant get this thing to work. Abkut to just throw it away

    No, I would not recommend this to a friend
