  1. Ryncody –

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

  2. Smitty –

    Nice power. Great installation! Kicker amps are great!

  3. Audioenthusiast1 –

    This amp is powering a JL 10” at 4 ohms with no issues. I was able to use the gain setup but struggled with the DSP.

  4. JCSKFAMILY –

    One of the smallest Amps I’ve ever seen and most powerful for the size

  5. MatthewVB –

    Works great with 500w 2 ohm subwoofer. Very pleased.

  6. Alarl –

    did what we wanted it to do, The install was excellent

  7. DeathvAngel –

    The power it gives the sun I had installed is crazy and I’m so happy with all my purchases.

  8. JDubs –

    I bought the 200 and my brother has to try and be bigger than me so he got the 500W for his car

  9. Kickersucks69 –

    If I could give it zero stars. I would. Impossible to set up without taking it to a “professional” 0/10 wpuld reccomend. Its already a bad design that easily overheats. On top of the key comluter system that makes the amp impossible to set up. Its veen over two months and I still cant get this thing to work. Abkut to just throw it away

  10. Great –

    For a small amp it sure does put out some power. Love it

  11. Joemamma1954 –

    I purchased a kicker amp for my vehicle and it improved the stock sound dramatically. So when i added a subwoofer, i wanted to stick with Kicker. I have not been disappointed. Easy setup, using the white noise downloaded from Kicker website. Very pleased with the product.

  12. Brian –

    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!

  13. InsigniaCharger –

    Excellent amp. Makes my 8 kicker speakers rock. Add the hideaway to your vehicle and you will have one heck of a system that can a really be seen

  14. Chuck –

    I wanted to add some low end to my music in my classic Mustang, this amp did the trick and sounds great.

  15. MarkH –

    I purchased this amp for my 2021 F150 with a 10” Kicker sub. This small amps works great! The amps works well with the auto/stop system in my truck.

  16. Tequiwi –

    This thing is powerful i cant believe how much power this little guy packs!

  17. Pleasantviewing –

    Nice compact amp for powering a subwoofer. Pleased with the punch it has in a small package

  18. MKVSupra –

    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

  19. Alligator –

    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 $.

  20. Benjamin –

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

  21. PIX3LPUSH3R –

    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!

  22. Mark420 –

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

  23. LeeW –

    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.

  24. Pocholin –

    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!

  25. Danimal365 –

    Perfect amp to boost the stock Bronco head unit. Tunes itself, incredibly flexible.

    Where were these in 2000?!?!

  26. Jaystang –

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

  27. Alex –

    I’ve recently had installed the Kicker Key 500.1 in my ’08 Mustang and paired up with a 10″ downward firing sub… Sounding great!!

  28. iLikeCoolTech –

    Great sound. Packs a punch!

    Make sure you get 4ga wire or a step down if you go up. Overall very good amp.

  29. Richard –

    Bought this as an add on for my system and it was worth it.

  30. Calvin –

    Kind of complicated to use and dont really understand how to use it. But not to hard to learn how to tune it properly

  31. David –

    This a nice little amp you get what you paid for..

  32. Mike –

    Awesome truck sub! This was a great recommendation by the auto tech

  33. Rjlope –

    Big bass in small package cleaner install size easy to hide and run worth it buying another for second sub

  34. user347713 –

    I purchased an open box item that doesn’t work, very dissatisfied

  35. KyleS –

    There were people at the door waiting to ask if I needed help finding anything!

  36. USAFR –

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

  37. DaleH –

    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.

  38. HaywoodJ –

    The setup I have for my audio is way better than the stock.

  39. SY72 –

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

  40. ChristopherW –

    This is a small but powerful little amp. Did the job!

  41. Ryan –

    Bought in may 2022, stopped working in September 2023, it has 12v power to the connection but the power light won’t turn on. At this price point I expect it to last longer than a year and a half
