Kenwood KAC-M1814 4-Channel Compact Bridgeable Marine/Motorsports 400W Max Power Digital Amplifier

Why did you pick this product vs others?:Have several of these in various vehicles. Compact size easily fits under larger center consoles and car seats with air space for cooling. Class D amp with 15A fuse, so low power consumption. Provides good clear amplified sound for car door and dash speakers. Gains adjusted near mid position, crossovers at 80Hz. Using separate dedicated mono amps for subwoofers. Not a competition or audiophile amp, but seems solid for a daily driver.

This product is small but it is powerful. I hear my music clear as day at 80 + mph. I used it with HDKit14 power acoustic radio and Rockford Fostgate speakers.

I needed an amp that had a small footprint. The installation was easy, the wiring came in a pigtail. The only issue I have is you cant use a 10 gauge hot wire, or ground. I had to swap out for a smaller wire. The sound is great, with a little tweaking, I am running 4 ,6 inch speakers with tweeters, no sub. Great amp for the money.

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.

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.

Really improved sound of aftermarket head unit, easy to install and inexpensive.

I purchased two of these to run the sound system on my 2023 Can Am F3. Very poor sound quality from both amps. They both started clipping out within a couple days of use. I replaced the two amps with one NVX amp and there is no comparison. The NVX amp runs the entire system at less than 1/3 gain and is clear and loud!

Purchased this to amplify the standard door and tweeters in my 2022 Tacoma. The compact size allowed me to install it right underneath the stock head unit. The wire harnesses that come with the amp are nice and long. For me, the sound is enhanced perfectly after tuning the gain/sensitivity. One of my new favorites.
