  • Great sound, lots of power
Very happy with this amp. It puts out great sound and has a lot of power. Installation was a little diifcult, but I expected that as I installed it in the trunk and had to run all the wires. It was worth the money so far, but I have only had it a short time.

  • Kicker lives up to its name!
Arrived on time. Packaged very well. Paid about the same I would have paid if I bought it at some other website. Its the second CXA amp I have. One under the driver's seat pushing the kicker door speakers (front and back) This new amp under the passenger seat, bridged pushing the kicker component speakers i have in the Q-forms kick panels. And two 400 watt kicker mono amps for the 2 ten inch subs i have under the back seat. All speakers and amps are kicker products and the truck sounds GREAT!!!!!! ... show more

  • Awesome Amp!!!!
Performs flawlessly. At first I decided to go with another brand amp to power my 6.5. You know the Brazilian maker that gets so many good reviews. After 2 warranty claims with them I decided to spend the extra money and get this kicker amp. I should of done it sooner. Its an awesome amp thats benched at almost a 100w rms above what they advertise. Dont even think about it get this amp! ... show more

  • Very nice amp, but large
So Far, So Good. After some hiccups with wiring and my head unit I finally got this thing running my 4 channel speakers. Adjustment was easy after using AI to ask about optimal settings, filtering and cross over. I feel the manual didn't provide enough detail sometimes and assumes you know what your are doing. I did not, so I needed additional assistance. However, I feel like I've got it tuned in now and the speakers sound great. Hopefully this will keep me from blowing any additional speakers. It is a little larger than I expected, but I really didn't look at the dimensions before buying it so totally on me. ... show more

  • Has performed flawlessy
Review after more than a year when I replaced a competitor's unit that seemed to have picked up the nasty habit of smoking. Has performed flawlessly, sounds great, doesn't get too hot and survived some minor water exposure when I underestimated the depth of a mudhole with no impact at all. I really liked the single connector wiring harness, it makes it easy to install or remove if needed. ... show more

  • Nice Amp for Mids and Highs
One of the factory front door speakers popped in my Fusion, so I set out to do some budget friendly upgrading. I purchased this amp on sale for $185 and easily installed it. I pre-wired the car with an Audio Control Line Output Convertor from the factory Head-unit to the trunk while waiting for shipping. I also installed a set of Kicker KSC6504's in the front doors and Kicker KSC6904's in the rear deck. The sound quality is day and night. The new Kicker system has vibrant highs and excellent mids. The speakers have modest bass, but that is not my use for this setup. I set the amps hi-pass filter @ 90-100hz to reduce the bass. I will be installing a Kicker CXA800.1 with one RF P3D212 Sub @ 1 ohm to get my bass. This little amp pushes 4 coaxial or component speakers no problem at all. Another great product from Kicker. ... show more
