    I bought this amp for my dune buggy and had limited space to install it. It is compact and fit nicely. It is also easy to connect and sounds great.

    The sound is great! I did a font stage upgrade, and my component speakers up front sound AMAZING now. The automatic DSP makes a huge difference in the sound quality! It's nice and small, and it could easily be hidden in the dash if you wanted to. The fronts are so good now, that I feel I need to do a subwoofer upgrade since my current subwoofers don't put out enough "oomph" in comparison.

    I have this amplifier powering Memphis Audio Power Reference 6x9 components up front and 6.5 coaxials in the rear door. For such a small footprint, it powers the speakers just fine. The amplifier was installed underneath the drivers seat alongside the Kicker Key mono amplifier by an audio installer. It was tuned by the mic accompanying the amplifier and it sounds great. A day and night difference between the stock JBL speakers that came with my 21 Tacoma.

    I wasn't expecting the incredible difference in the Kicker door speakers. The sound is amazing at 50 watts per channel. My truck cab is huge and I also added the Kicker 8 inch underseat subwoofer. Now I just jump in my truck just to listen to some good music. Seems that by keeping all the speakers and amp Kicker brand, sound better.

    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 6x9 component in front Kicker KS 6.5 coaxial back Kicker 8” sub with 500wts F150 crew cab

    Purchased this to install with my factory radio head unit and couldn't be happier. Its like night and day difference in sound quality with its built in dsp and the power level is just what i was looking for to fill the cab of my pickup.
