    Works very well for a small amp! I would recommend it to other people if they need a new amp! Definitely worth it.

    Bought 2 of these, one to run an 8" enclosure and one to run a 10" enclosure. I love them. Exactly what was needed. They run cool and clean. Price was awesome.

    Paired with a Kenwood Receiver, 4 kicker 6x8 speakers and a 10" Kicker box Sub .. My Review Mirror vibrates but very little sound escapes the truck (f250) unless a door is open # Its Everything that I Wanted.

    The kicker cx 400 was the perfect pairing for my 12in. Subwoofer and hits pretty good. The only thing that was bad was kicker not packaging the bass knob along with this amp. They're really trying to get every penny. Best buy staff was helpful and picked up curbside without complain. Would definitely buy again.

    Didn't know if my old Amp was burnt out or what but it cost more to inspect it than to install this new one. So, it gets the job done better than the one I didn't get inspected. Once I add more I'll try my old amp.

    I mean it's a solid kicker! You cant go wrong . It matched up perfectly with a 10" sub in my girlfriends compact car. A little more power than the car needs without rattling panels. A slight adjustment fixes that.

    Enough to power a small sub with enclosure and not bad for its price either.
