    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.

    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.

    Bought this to power the 10inch Kicker Sub I got for my car to add to my factory system. Handles the sub with no issue whatsoever. Best Buy did great job installing and was able to hid it away in my spare tire area. Great job.
