  1. InsigniaCharger –

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

  2. Sashaw85 –

    One of the best amps ive ever had does what it says.

  3. Poping –

    Two Kicker 4 channel amp has a big punch I love the sound crystal clear surround sound 3D

  4. Alligator –

    So far so good! The DSP sounds great and seems to have plenty of power. It was easy to set up and auto tune. I didn’t really like the small gauge twin power and ground but see no real issue with it. I paired this with the matching Key 500.1

    My only negative is not even related to the amp but I purchased it open box “excellent” condition. Everything seemed to be as it should but there was some noticeable scratches on it. I probably would have still purchased I I known about them just to save a few$.

  5. BestMoon –

    My son says it’s the best. Him and his friends are building his pc. They all recommend he get this. So far great

  6. Playstationplayer –

    Good quality and well put together. Very happy with these for my sound system in my car! More than enough power.

  7. johnnyr –

    Provided clear audio at higher volume without the distortion. This amp works for what I needed.

  8. Mstjo –

    I installed it in my 2003 325i and works great. Can definitely hear the difference with the auto correction

  9. Blee10 –

    Unbelievable performance for the price. I highly recommend this amp/dip to improve audio your mobile listening experience.

  10. blaw –

    good sound i am happy with it makes my speakers boom

  11. Hunkjunk –

    is just what i wanted
    great price works great easy set up
    so easy to use

  12. Gamerz –

    I really like the fact that this amp is super compact and can fit into small spaces. I have mine connected to 4 6×9’s and it’s installed behind the dash where my deck is. The only draw back that I can think of is that I can’t adjust the settings if/when I need to conveniently.

  13. Lucky –

    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

  14. DougF –

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

  15. Steve –

    This Key amp has to be the best kept secret in car audio. First of all, it has solid reliable power. Want to upgrade the sound of your system? Just add one of these. Effectively doubles your constant power to the speakers. The best part is that it comes with a mic so that you can run a pink noise setup that is specific to your car. The same thing that professionals use to do audio setups in large PA systems. Really works well. If you’re not into doing that, have it installed at Best Buy. You will not regret it.

  16. Druss –

    Not worth it. Took it back and got a different amp. The new one is easier to work with and delivers without an issue.

  17. Bigceestero –

    They did a great job,system sounds great. Really appreciated

  18. Chad –

    I bought this amp to power the front stage in my F150. I’d previously had subwoofers + amp and the door/pillar speakers replaced. The guys at the audio shop ensured me the head unit would be fine driving the door speakers even though I had reservations from many years of car audio. The head unit did work and it sounded pretty good but the door speakers couldn’t keep up with the subs so I wasn’t able to use any of it to it’s potential. I installed the Key in bi-amp mode powering the front door speakers and pillar tweeters. I left the rear doors powered by the head unit. Wow, what a difference! The size of the amp defies it’s performance even though I’d seen videos of people measuring it at 50W a channel. It’s also very clean. I can turn it all the way up and the sound is clear, non-fatiguing, and doesn’t sound as loud as it is. It also solved other problems with the F150 like the head unit output turn-on. Normally Fuse 23 is tapped as remote turn on but it only works when the ignition is in the ON position. It switches the remote turn on to powered output to use as remote turn on which I did to turn on the sub amplifier.

  19. Nelson –

    Works just as intended. Adds a good full sound and a good amount of extra volume.

  20. KDD421 –

    Sounds great and very light weight. Very easy install

  21. KathleenG –

    It’s nice to have the amp installed behind the dash, so it’s out of sight. I thought I’d be able to adjust the bass a little more. Apparently, this 4 channel amplifier does it for you…

  22. RobG –

    The amp was recommended and it has definitely proven to be a great purchase

  23. YoungJefe –

    Definitely gave my subs quality and was reasonable loud

  24. Jmk82604 –

    Great sound. Change in sound quality was amazing
    Love it

  25. JoJo –

    Sounds great with a component set of speakers. Great way to improve sound and retain factory head unit

  26. Beba –

    Happy with the great job they did on my music system. Happy coustermer here

  27. Azkid –

    If you’re looking to get a more clear and quality sound then this is your little amp. It doesn’t get loud, keep in mind is 200watts only. But the auto tune using the microphone and DSP makes you reconsider if loudness is better. I was blown away of how clear and crisp music sounds.
    Paired with
    kicker KS 6×9 component in front
    Kicker KS 6.5 coaxial back
    Kicker 8” sub with 500wts
    F150 crew cab

  28. Andrew –

    Great amp and it’s easy to hide under your dashboard.

  29. WannabeTechie –

    For my 2021 Ford Bronco, this was a huge upgrade. Loud and clear to Alpine speakers.

  30. Oskapers –

    2 amps in car, this one is hidden and makes speakers sound amazing

  31. Matthew –

    Easy to set up, Great sound stage, very small & compact, runs cool, excellent tech support. love it

  32. SLINGSHOTdj –

    So far its suppling the power i need. The two seperate volume controllers help baalnce the speakers because they have different wattages.

  33. Unknown –

    Super i live the way it has enhanced my music. I really really really love it . I would recommend it to anyone for a great sound in the car.

  34. Lihamp –

    This amp is compact and will likely fit in many locations. It really transformed the stock system in my Santa Cruz. It’s DSP function is icing on the cake.

  35. Elshaneo –

    Better than any factory amp, easy install, and tunes itself. It’s very compact cand can be mounted anywhere

  36. ChrisMc –

    This tiny amp is phenomenal. Small enough to put behind the dash in my 21 F150. Super easy install and the auto setup is awesome

  37. AmandaW –

    It was alright. No the greatest on communication got tossed bck and forth between stores and rude people .

  38. Jimmie48 –

    Seem to work great!!! Speakers are loud and clear and its just what i needed

  39. JoeD62 –

    Very nice. Small, easy to tuck away yet it gives the punch needed to the speakers. 100% recommend!!!

  40. RonB –

    I’m blown away at how good this sounds. I first purchased Kicker 3 way 6×9 speakers for my 2023 Subaru Outback base trim model and the audio sucked. So I upgraded to the Kicker speakers on the sales guy’s recommendation. The sound was better but treble was out of whack and it still sounded bad. So I had Best Buy add the Kicker Key 200W and after the EQ was auto adjusted – the audio sounds amazing. Accurate pin point treble, great bass, just about everything I could want for my listening taste. (Jazz, classic rock, folk, world, etc..,)

  41. Brian –

    This amp is AMAZING! I originally upgraded my 2016 Tahoe factory speakers with JL Audio C1’s and was happy with how it sounded but knew I still had the ability to improve if I added an amp. I searched for weeks and decided to buy this one because of the built-in DSP. The set up is very easy once it’s installed, and the microphone that listens to the speakers during audio setup is like magic. My music is perfectly EQ’ed and has twice the volume. The setup takes less than 7 minutes and it’s all done with a click of the microphone that comes with it. I’d recommend getting the Key 500W for your sub, if you have one. It also has built in DSP and will pair with your 200W amp for concert quality sound!

  42. DouglasD –

    Great amplifier. Sound quality is excellent and really good value.

  43. JayT –

    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.

  44. johnski –

    I bought this Kicker amp to replace a blown amp in my car. I bought it over 2 years ago and have never had a problem with it. I would gladly buy it again

  45. Arod –

    Definite difference, just wish it had more power for aftermarket speakers

  46. yourmom –

    This amplifier works reasonably well and is in a very small footprint, it was easy to find a place to install it.

  47. Willidx4 –

    Works great easy to use dsp the amp clearly out performs its rated specs

  48. FredO –

    Works great !! Even have an app you can download to get tuned perfectly!!

  49. ThomasT –

    Great sound if you want to add more power to your stock head unit. It may be a little complicated to install but its worth it!

  50. Monty –

    Checking this amp our for the first time, I was skeptical. It’s so light. It’s class D. It doesn’t require you to run 0 gauge welding cables from your battery. Frankly, it looked like something I would get from K-Mart. How wrong I was. This thing is musical. It’s powerful. It blows the doors off my truck while staying cool as a cucumber. Granted, you MUST run the DSP setup. Without it, it’s a nice amp. After running the DSP, which is trivial, this little gem will make you swoon. Buy it. Now.
