Very small compact and hits hard in my coupe, doesn’t make my lights dim solid purchase for a stealth system

This is an excellent amp for a subwoofer. The amp has its limitation, as the size suggests, but it is very capable, configurable. I really liked the fact that is has the option of using high signal or low signal for input, time saver!

Great quality, power, and size! The setup tokes a little research but makes tuning simple. Perfect for applications where space is an issue. I have it mounted under my seat with plenty of space to spare. Highly recommend

Tiny but effective amp. Perfect for sub requiring 500w RMS. Setup/calibration was easier that should be possible.

Loads of power from a small package! I am running this amp at 300w 2ohm and it pounds on a JL W1 10” in a sealed box. It is easy to hook up and set was a breeze. I paired it with the matching key 200.4 The only negative is not even about the amp. I purchased it open box “excellent” and it had some noticeable scratches. I would have purchased anyway had I known just to save a few $.

Wow! That’s all I can say about this tiny little powerhouse of an amp! I have it paired with the KickerKey200.4 which runs my front sound stage. The KickerKey500.1 amp did wonders for my sound system setup. First of all, the installation couldn’t be easier due to its size. I have this and my other key amp both under a passenger rear seat of a 2017 Tahoe, completely hidden from sight. The initial setup process to set the gain was very simple to understand with the instructions provided. Make sure of two things: 1- download the sound wav file from kickers website and do not wirelessly stream. Instead use a wired or aux connection. Bluetooth streaming loses quality and affects the ability of the key amp to do a 100% effective job. 2-If you switch between radio detect on the kickerkey200.4 amp while hooking this one up, you must disconnect your battery. For some reason, the amp does weird things and has to be reset. So, pay attention to your DA offset or 12V selections on the amps and disconnect each time when switching for about 1 minute. After I ran the key set up for the 500.1, I instantly noticed a tremendous improvement in the sound quality of the subs performance. I’m running a JL Audio 10W1-V3 in a ported box. Before the sound was very “bassy” and didn’t have a lot of dynamics in the overall range. Now, I can hear the drums separately from low range vocals and everything in between. It made my factory stereo come alive! I was impressed with the addition of the first kickerkey200.4 amp, but this added to the setup has blown my socks off! It can run 500watts RMS down to 1 ohm. I tried swapping out a single sub with a dual subset up and thought my windows were going to blow off! Just one sub with this amp is more than enough for my preferences!

This amp is perfect! Clean sound, lots of adjustments, and lots of power in a small footprint. I paired it with a ported 2ohm kicker 12 in sub and it bangs. It can even do 1 ohm so I thinking about rewiring my 2ohm dvc 12 and push 500 watss rms. You can not beat this set up at this price!

Aaron installed a kicker key 500.1 for a new custom sub box I had previously installed in my Bronco. Clean install and sounds great. The Factory systems in these new Broncos are horrible. It sounds great now after the speaker upgrades, amp installation, and FORSCAN changes.

Excellent - Used in addition to a 10" JL Audio sub in my Audi with B&O Sound System. This amp allows easy integration without setting off any errors. The tuning was easy and it produces more than enough power!

This is by far the best amp I've used. Very compact. Easy to adjust. It supplies perfect power to my 8' woofer. Price and quality for a tight fit equals easier install.

Great sound. Packs a punch! Make sure you get 4ga wire or a step down if you go up. Overall very good amp.

Perfect amp to boost the stock Bronco head unit. Tunes itself, incredibly flexible. Where were these in 2000?!?!

I love this product. It has taken my sound to new heights... My music feels very complete niw

Good amp if used with the 12' Kicker CompR subs. Don't mix& match brands for best sound quality.

Quality amp that is super powerful for its size. Sounds amazing

Amp seems to be performing well so far.Lots of power, and has a good sound performance wise

Great sounds out of small package. I was amazed by the wattage and features this little guy packs.

Works like a charm. Easy setup, auto gain tuning feature really helps!

Works really well just to small for the sub i bought. The employee told me it was the right one but it was to small. Also the price is high for the amp.

Great product. Used to power a Kicker sub woofer. Recommend to all
