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.
I decided to go for it and after a 2-3 hours installation, I ran the automatic setup in BI-Amp mode and BOOM! What a difference! I could not believe it!
All the tones were there, the sound stage was amazing, great highs, lows and clear vocals. Everything just sounded 10 times better.
Only when you start to toggling the before/after switch on the microphone wire, you understand how poorly it sounded before.. Just amazing.
Go for it!
If you are adding this amp to a newer vehicle and have no sound from your speakers when finished, you might assume you have a bad amp. Try pressing the little button on the amp that is supposed to trick the radio into thinking that all speakers are connected. If STILL no sound (that little button on the amp is ineffective on many newer vehicles) you'll need to buy and install another $60 special box of resistors called a KISLOAD4 (also from Kicker) that tricks the factory radio into thinking the speakers are plugged in.
For example, my vehicle is a 2020 Jeep Wrangler with factory Base audio system, and I needed the extra KISLOAD4 box to make it all work.
Kicker audio has great (and patient) technical support if you need it during install.
The size is so practical, you can hide almost anywhere. I didn’t use the integrated DSP, I don’t think it’s required in my application.
I used it for my factory stereo, using a 4 channel LOC and I got a very clear signal, no weird noises or distortion at all.
Would buy it again without hesitation!

I installed this after installing some Focal speakers and the improvement in the sound is great after the auto calibration!
The results are staggering. Somehow my ancient tiny speakers have acceptably good clarity and even acceptable levels of bass. They are all matched in volume, and the sound stage sounds like it’s right between my ears when sat in drivers seat.
Superb product for lifting an worn out old stock system into the present day.
Impressed with kicker yet again. Have ordered a set of their entry level speakers now as a follow up from these excellent results.
Just a word of warning though… in old cars with earthed negative returns on the speakers, you will need to wire both negative and positive from/to the speakers and cannot earth the speaker inputs to ground. Because It’s a class D amp. (Same with any class D amps, not just kicker). Enjoy.
There is also just a whisper of white noise from the amp when powered up, but no music playing. This needs to be improved for future models Kicker!
