KAC-M3001 600W Class D Monoblock Compact Digital Car/ATV/Marine Certified Amplifier

I love this little amp! It is a solid performer with built in low pass crossover adjustment as well as a sensitivity adjustment. It does a terrific job driving my two 10 inch subwoofers at 2 ohms and it has barely gotten warm. This is a very small amp, you should have no trouble finding a spot for it, it is smaller than a toddlers shoe box. It barely gets warm at all, I would have no problem installing this under a seat in a car and forgetting about it. The sound is clean and pure. I played tracks I've listened to for decades and they sounded terrific.

I installed this to power an old Rockford Fosgate 10" subwoofer I had layng around and put it in my saab vert. Not looking for or expecting to rattle neighbors windows, just wanted to take the bass responsibilities off of my 4 Infinitiy Kappa's that were sounding a bit muddy. Happy to say this amp powers the subwoofer with ease and really fills in the bass. Just what I was looking for. Yes you can feel it but not obnoxious. The Kappas are once again sounding bright and clear now that I'm only asking them to push 120hz+. I was a bit concerned because of the size - but really happy with this unit. Size is a bonus as I did not have a lot of trunk room and this sits in the corner right behind my 4 channel Pioneer that is handling the other speakers.

I received a replacement unit, checked all the connections and outputs, and it works very well! The bass is loud (powering my 10" Rockford Fosgate sub), the sound is clean, and the adjustments are easy. I like that it is very compact, as it was an easy replacement for the factory sub in my vehicle. I can easily make the whole truck shake, without noticeable distortion. Overall, an excellent value, and I can't imagine any reason why I would want to spend more. Original review: Got one for Christmas, but appears to be DOA. The unit powers on, but makes no noise. After testing all other components and cables from the head unit to the sub, this appears to be the problem. Will return and re-order, hope for better quality on the next one.

I installed this amplifier for a friend to replace a 20 year old Altec-Lansing that at the time was the only amp small enough to fit in the space he had available without overheating. When I installed car audio as a profession A/B Class amplifiers this compact would only be good for around 20 watts and used on tweeters and the few D-Class amplifiers on the market were more than an iPhone 7 and delivered only around 50 watts...and were still WAY bigger than this Kenwood is. I've seen names change ownership through the years and was not surprised to see made in China on the packaging although I was a bit puzzled why a Japanese company would use China to make its goods. I only hoped the Kenwood quality was unchanged. Installation was simple as the power connection terminals were the common screw type found on nearly every amp brand at some point. The speaker connections are two bonded 16ga wires to form one robust +/- speaker lead. It has a wide range low pass xover (50-200hz) and ample gain control that allows from 0.2 to 4 volts line level input. The unit used a 30 amp mini ATM fuse which calculates out to about the 300 watt continuous output it claims. My friend still had the JL Audio 8 inch sub we installed in a sealed box, tuned to about 50hz. There was no bass boost on the old amp so we used a small external equalizer and kept it in place with the Kenwood install. After some volume and crossover adjustments we put it through about an hour of favorite listening tunes at volumes loud enough to earn a dirty look from a nearly neighbor. I forgot to measure the db level but in all it operated at an output level that would have easily heated up an A/B amp to the point of being too hot to touch for where we installed it, behind the seat with carpet all around it. After all of that it was only slightly warm. Bass was good, tight and clean the entire time, no headlight dimming, no turn on thump or engine noise. My friend liked it and wants another for his wife's car and I'm thinking of using one in my own car now. I definitely recommend this amplifier for anyone wanting a simple, effective system upgrade.

This little amp is working well to drive my PIONEER TSSWX2502 10-Inch Shallow-Mount Sub . Unfortunately I have to use speaker level input from my stock stereo because of how integrated the stereo is into everything on my Nissan Leaf. You'd expect for the speaker level input to be quite high but I actually have the gain on the amp at full and it is just barely loud enough compared to my other speakers. I was very fortunate to have gotten such a small amp though. If it was any bigger, like even 'small' non-digital amps, there is no way I would have had a good place to mount it. The dimensions on this amp are seriously tiny. I mounted mine just to the right of the head unit, above the glove box, behind the dash. It was the only good out-of-sight place. I'm going to try changing my input setup to use an outboard speaker->line level adapter and/or connecting it to the head unit differently. The bass response just isn't quite right but it could be this factory head unit. The same enclosure sounds much better in my other car with a different Kenwood amp (that is small, but too big for my Leaf). So I'm taking one star off. I'll update my review if I find a better setup for connecting the inputs on the amp.

This amp worked great for my 2 10" kicker subs. I was surprised by how small it was compared to my old amp and didnt think it could push the sound I was looking for, but boy was I wrong. Good price and well worth the money in my opinion. It does not have an overheating light though which I was disappointed in

Kick ass little amp for its size, I wired 2 6 1/2" subs in series and it runs well. Small enough to fit almost anywhere. I would purchase again.

Does what it needs to do for a small amplifier.

Works perfect

Bought as a gift and it didn’t work upon install and it was past the return date
