Customer Ratings & Reviews

A little pricey but it also has the auto start stop technology built into it which is key for newer cars and trucks great amp overall and very tiny for the power it puts out just thought it was a bit too much to pay for a 200 watt amp but overall very pleased with it.

Kicker Key 200.4 Amplifier Kicks! Great product. Easy install. Compact.

Purchased this to install with my factory radio head unit and couldn't be happier. Its like night and day difference in sound quality with its built in dsp and the power level is just what i was looking for to fill the cab of my pickup.

Great sound and the small size made it easy to pjt anywhere

Sounds great. Easy to setup/program. Kicker provided great technical support.

Great amp very compact w lots of power. Takes up minimal space

Very good amp for it being so small this thing has some power to it

Good quality component. Easy to install. Very please with the results

The sound is great! I did a font stage upgrade, and my component speakers up front sound AMAZING now. The automatic DSP makes a huge difference in the sound quality! It's nice and small, and it could easily be hidden in the dash if you wanted to. The fronts are so good now, that I feel I need to do a subwoofer upgrade since my current subwoofers don't put out enough "oomph" in comparison.

Great amp, sounds great and fits right behind my factory radio!

Looks cam be deceiving! If you are looking to upgrade your sound start with this amp prior to upgrading your speakers. I have nothad any trouble with this amp since install. The instructions were clear and set up was pretty easy.

Great purchase, amp has good power and the DSP setup is super easy!

Great addition to my car stereo! Awesome sound! Best Buy installed this and speakers. Really woke up my car stereo! Very pleased!

It fits in my Mustang! It works great too! Excellent power to my Kicker speakers front and rear. More than enough to rattle my memorybox! Trust me. I know what I'm doin' when I'm reviewin'.

Love it, great little amplifier fantastic sound !!!

Eaysy to install. A bit high in price, but worth every penny. Definitely improved my car audio.

Best bang for the buck! Was skeptical at first but the auto running works like a dream

This amp was installed just to amplify my door and 6x9's and wow does it sound good. Good amp!

This amp packs a powerful punch for its size. Installed by Best Buy Tech Team. TotalTech membership benefits are amazing. Paid for install of all stereo components to include six speakers, subwoofer and two amplifiers

Perfect for what I need and small enough to not take up too much space. Expensive
