    Might as well keep this simple. This amp is incredible. It was recommended by the BB installer. I saw the reviews and ordered it. It’s everything they say. The BB installer said he is putting one in his own truck.

    My first experience with this brand after having used an Alpine mobile audio amplifier in the past. I saw that Kicker seems to have a good reputation and thought I'd give them a shot. I've been using it for about 6-weeks now and it works like a champ! Good decision!

    This little amp works great to power the door speakers in my Tacoma. I have Focal components in the front and Alpine coax in the rear. I originally had them powered by my Pioneer touchscreen headunit but they felt lacking so I bought this amp. I am so glad I did. My speakers are so much clearer and much louder as well.

    KEY 180 in a 2020 F250

    Took a few tries to figure out the dsp calibration but definitely worth it. I installed it on a 2020 F250 with sync3 and hid it in the dash behind the stereo. I do plan on upgrading the speakers but I'm not in a huge hurry now because it made the factory speakers sound so much better.

    Not a bad amp, the only issue is how it was installed by the techs at Best Buy. They didn’t hook the remote wire so my amp is not shutting off. My window plug was unhooked after all the work they did and they said they tuned the amp and well that was not done either, the gain was all the way down. More training is needed for these guys.

    Never purchased extras like this for a car stereo before; but the difference in sound quality is amazing. Well worth the price; I’ve got a second car I’m building and when that’s done will be adding the same system in that one too.

    BETTER THAN EXPECTED HOOKED IT UP TO 2 6.5 JL AUDIO 2 WAY SPEAKERS AND 2 6X9 JL AUDIO 2 WAY AND TWO DOME TWEETERS AND IT SOUND GREAT AND PUSHES THEM WITH NO PROBLEM. BETTER IS THE EQ WAS CUSTOMIZABLE AND DIDNT HAVE TO LEAVE THAT MICROPHONE CONNECTED TO TURN THE AUTO EQ FUNCTION ON AND OFF.

    Get this for your door speakers and they will thump. I bought brand new speakers for my 350z and put this amp with them and they sound amazing! Don’t expect them to sound like a subwoofer but they will give you more bass!

    This fit behind my kenwood stereo. Out of site out of mind. My speakers are clear and louder. And can use my settings in my stereo more effectively. Best Buy did a great job installing it.
