Review: Pure gold! - What an exceptional little amp. The sound quality is phenomenal, the clarity is fantastic! I combined this with Kicker KS series 6x9 components up front and 6.5 coaxial speakers in the rear of my 2019 F150 XLT. I wish I had done this years ago. Only small crux is I ended up needing to run a remote turn on wire as the auto turn on wasn't functioning properly in my truck. One wire and a lot of rerunning wire and it started up with zero issues. I really hope that Kicker expands the Key technology further in the future. It's now a proven concept that can match the performance of most DSP setups but adds the value of being DIY friendly for those of us who prefer to install our own equipment or cannot afford a full DSP setup and the associated installation and tuning costs and or headaches. I'd love to see Kicker offer a higher watt version of this amp. If and when they do, I'll be seriously considering an upgrade. Not to say that this isn't powerful though, I honestly can't crank it all the way up because it's too loud. I love being able to say that! Also it makes all kinds of music better. It truly doesn't matter what you listen to, you will hear instrumentation and vocals that you have never noticed before while listening to your all time favorite songs.
Review: Nice AMP. - Awesome sound.. install in a 2023 Honda Ridgeline, that was the hard part...the Noise canceling device in the Honda was a pain in the butt to find and shut down. I would buy this amp and again.

### ⭐⭐⭐⭐⭐ Nice compact amp.
*by L***. on January 8, 2026*

This is a compact amplifier with great sound stage. I installed this in a 2025 Kia K5 GT. The amp cleared up the sound in my door speakers so I can actually hear the words at a decent volume. I also replaced my stock door speakers with a set of Rockford Fosgate speakers. Great buy.
