Kenwood KAC-M3001 - Power a sub wherever you go
Kenwood's KAC-M3001 compact mono subwoofer amplifier will power the bass in your vehicle with up to 300 watts RMS. That's enough to hear the bass clearly above the noise of the road, trail, or waterway as you travel along. This little powerhouse will fit almost anywhere, including a storage compartment on a boat, motorcycle, or ATV, so you can put great bass in whatever vehicle you wish.
High-level inputs ease installation
The KAC-M3001 will accept a signal from just about any source, whether you're using RCA cables from an aftermarket receiver or speaker wires from a factory radio. When you use the speaker-level inputs, the amplifier will sense the signal and turn itself on, so you won't need to run a remote turn-on lead to your car stereo.
Compact Amplifier
The Kenwood KAC-M3001 compact Class D mono block amplifier is designed to drive a subwoofer (or two). The amp features a conformal coating on the circuit board to protect it from moisture. This allows you to use the amp for motorcycles, marine applications, or on All-Terrain Vehicles (ATVs). The KAC-M3001 delivers 200 watts RMS x 1 channel at 4 ohms. It also gives you 300 watts RMS x 1 at 2 ohms.
Connections
Power/Power Control Connections: The power, ground, and power control connections are 0.35" wide screw terminals. A Phillips-head or flat blade screw driver (not supplied) is required to tighten/loosen the terminals. Spade connectors or ring terminals are recommended. A minimum 10-gauge wire is required for power and ground.
Power Control: The Power Control wire should be connected to the head unit's remote turn-on lead when an aftermarket unit is used. This wire does not need to be connected if you're using speaker level inputs. The Signal-sensing Turn-on feature will turn on the amplifier when an input signal is detected.
Line-Level Inputs: The amplifier is equipped with a pair of RCA inputs for connecting a stereo RCA patch cable from the head unit to the amp. If using a factory head unit, or a unit without preamp outputs, you can splice the speaker wires to an RCA plug, maintaining the same polarity.

Does what it needs to do for a small amplifier.

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.

Good power for its' size. You're probably planning to use it for a sub or center channel speaker. Be sure to notice that it puts out only 200W at 4 ohms. I used it to power a Skar 8 inch sub and it does OK with the sub set for 2 ohms. Not a powerhouse but fits a lot of places, looks good, and works well. I will probably upgrade to more powerful amp now that my sub is broken in. Comes with wiring harness that has nice, long wires.

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 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.

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.

Gone are the days when you needed large amps and wasted space to produce big sound. I am using this amp to push a slim mount SKAR 12 wired at 2ohms and it sounds great! I mounted the the amp and a 4 cahnnel kenwood in the small storage space behind the passenger seat in a 1978 Corvette. I now have an amazing sound system with minimal space used.

Really didn't think this amp would really be powerful enough to run a decent sub, but I am really impressed that it does it with ease. I have it on a Alpine Type S 10" sub and it really motivates the sub with good clean power. Best thing is that it's in a place that doesn't have a lot of air flow and it still doesn't over heat. I just took a 5 hour drive in 90 degree heat and had the volume turned up a good amount and it still kept rocking just fine.

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.
