## Customer Reviews

### ⭐⭐⭐⭐⭐ This is a gem! F..ng A!
*by K***O on March 6, 2020*

I'm impressed with the power of this little thing.I wanted to keep using my factory radio which I love, big buttons, big knob, supper convenient, but get better speakers and get an amp for my Honda CRV 2014 LX. I spent some time researching and ended up with really good expensive Alpine speakers, an amp, but they still sound like CRAP. It took me some time to figure out that I needed DSP (Digital Sound Processor) which will level the output coming from factory radio.This little beauty is like Alpine 445 u, but this one has DSP. And OMG it sounds sooo nice. Especially after auto tune. Freaking heavens opened to my ears.It doesn't require much power, so I just T-cut into my radio's harness that gave me sound, power, remote start. Turned out to be super small and neat install.Love it.

### ⭐⭐⭐⭐⭐ Great performance, small footprint.
*by J***M on December 18, 2020*

I installed this in a 2018 Ford F-150 XLT. It fits comfortably in the dash behind the head unit, secured with zip ties. It is powering four Kicker CS-series speakers (one in each door enclosure). I also have a Kicker Hideaway 8" powered subwoofer behind the rear seat. I am using the stock head unit.I have been very impressed with this amp. I installed the Kicker door speakers a week or two before the amp, and while changing the speakers out was a big improvement, adding the amp improved the sound quality by leaps and bounds, not to mention the volume capability. I had a 2013 F-150 FX4 with the Sony system previously, and my current sound system cost about a third as much as the Sony upgrade and sounds at least twice as good.

### ⭐⭐⭐⭐⭐ Best sound for Toyota
*by B***L on March 23, 2021*

Toyota is known for crappy sound systems. I replaced the factory speakers with Kicker, then added this amp. Follow the directions on how to set it up. After the set up was done, it was amazing. Using the compression with the time delay, wow.
