    Just the right amount of kick on budget. The quality of sound was good with the in-dash receiver but the amp added the improvement I needed to truly enjoy my music. Excellent low end.

    This amp is awesome! I will admit, I was skeptical… my car had a 6 channel system and this amp is only 4 ohm stable so it took a little extra effort to separate the channels from the front stage of my Camry, but it was well worth it. The sound quality is amazing, when I first heard the amp pre- dsp I wasn’t that impressed. Take your time and follow the process and make sure you put the mic where you ears will be. It’s running two 6x9 3 way infinity kappas and two 6.5 midbass in the rear doors. If you’re on the fence, buy this amp! Highly impressed.

    Great sound, easy installation, perhaps not as potent as a full size amplifier but the DSP makes up for that. Great mini amp if you don’t have room for a full size amp.

    A little pricey but it also has the auto start stop technology built into it which is key for newer cars and trucks great amp overall and very tiny for the power it puts out just thought it was a bit too much to pay for a 200 watt amp but overall very pleased with it.

    I purchased the amp for my F150. It improved the ability of my Sony head unit to overcome the road noise in the cab. But I really like the "Auto-EQ". DSP with equalization and time correction. It ran for a few minutes then Wow!. My truck sounds so much better. It put the stereo image right in the drivers seat!

    I had this installed a couple of months ago and just now getting to the review. Kicker always had a good report in general this amp is small, has the power with 4x50 watts you do not need more that that and it fits under the seat . I would recommend to anyone that has a small budget

    This was the critical game changer to my 2018 4runner system. I changed the head unit to a Pioneer and added this product. So loud and crisp to the factory speakers can't turn up past 16. Volume goes to 40. 5 Star.

    My Best Buy installer recommended this amp for an easy upgrade to an existing Toyota system. It has exceeded my expectations by not only giving me a quality sound improvement but adds just enough volume to really let me enjoy my stereo.

    Great for Toyota Tacoma Stock System

    Purchased this to give my stock 2019 Toyota Tacoma a boost in the stock audio sound. (I have the Entune premium 7" unit, non-JBL). Using a guide on TacomaWorld, some Metra harnesses and my time I got it wired up and then installed. I was impressed. Now granted I had already replaced the door speakers and tweeters with Kicker replacements so this amp was a compliment to that. I will say that it seems highs/treble are filled using the amp but for my ears, using the in-dash adjustment corrected most of it. I was looking for more mids/bass with this amp anyway and I got it.

    I purchased this amp to power my Alpine S series components in the front doors and pillars. This combined with the 500w Kicker Key sub amp provides plenty of sound in my F150. Very clean sound using the DSP.

    I'm blown away at how good this sounds. I first purchased Kicker 3 way 6x9 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..,)

    Wrapping up installation and tuning, so far very impressed! It's shockingly small but added so much better sound to my speakers.
