  • All that and then some!
Style: KAC-M1814
Compact and works great!!

  • Power to play!
Style: KAC-M1814
Power to play! Nice clear sound pushes my 4 speakers perfectly. Doesn’t break the bank.
Reviewed in the United States on April 29, 2025 by The wattage must be different than car audio. They are not loud at all… don’t wast your money!! They are not what 800 watts should sound like.

  • Compact

Stuffed behind the dash on a 01 f-250 powering 4 scar audio door speakers and two tweeters, huge improvement. Louder clearer audio.

  • Works well
Style: KAC-M1814
Bought this to put on my Harley with 4 speakers. Definitely a huge upgrade over stock, but still not quite enough volume at highway speeds, not really any fault of the amo though. I will be buying another to install so I can run each set of 2 speakers off of a dedicated amp. Love that it can take the input direct from a radio without the need for a line converter. This was a perfect fit inside a 2013 road glide fairing between the glove box and inside wall and would have fit well above the radio except I have the cb module, which takes up half the space in there. I have only put around 2500 miles on it, some in severe rain, and it has not missed a beat. ... show more

  • Perfect for motorcycles
Style: KAC-M1814
I installed this on a 2014 Harley Ultra limited paired with Rockford Fosgate speakers. Install was very simple, and space constraints weren't an issue.

  • Big sound, small size!
Style: KAC-M1814
I've had 200+ watt Pioneers installed for about a year with a Kenwood head unit, sometimes when playing content from my phone I really had to crank the volume up to hear it well enough. Now with this amp connected, I barely need to go above 25% and it has fantastic audio quality. I've added the Kenwood compact sub to my setup so the Pioneers handle the mids and highs (and some low Hz), the compact sub handles the lows - all setup using the crossover in the head unit. You really have to tune your setup if you expect this to sound good - go through your head unit settings, set the speaker size, distance, etc... Don't leave everything to default. I set the line sensitivity at about .3 (which is about 65-75% turning of the dial). HPF off so I can change settings on the fly at the head unit. Oh and the size - this thing is so compact, I was able to tuck it under the dash behind the 'ol glovebox. Everything you need is included, RCA cables, wiring harness, even some zip ties. Like I said, when you tune it against the settings in your head unit, the audio quality is fantastic. ... show more

  • Great addition to after-market head unit.
Style: KAC-M1814
Great sound! Installed in a Jeep JKU with Kenwood Excelon head unit and Blauhpunkt sub. I love it was pre wired and fit right behind the head unit. Puts the factory keep unit to shame with the Ground Zero speakers I added. 400 watts never sounded so good! Definitely a winner!

  • Don’t waste your money. This is an expensive nightmare.
Style: KAC-M1814
Wiring nightmare. Stay away from this super junk. Didn’t bother to bridge RCA’s so you will need a splitter. Wiring harness is not intuitive and is a major hassle compared to a simple connector style. I was so incredibly frustrated I almost threw this garbage part away.
