Kenwood KAC-M3004 Compact 600W 4-Channel Car/Marine/Powersports Digital Amplifier

This little amp put a smile on my face! I did not have much faith the rated numbers were accurate, turns out this little bad boy is underrated! I have an SMD Amp Dyno and decided to try out this amp in bridged 2ch mode...it surprised me!Rated @ 8 ohms (bridged) - 100W x 2 @ 14.4VMeasured wattage at 8 ohms (bridged) - 132W x 2 @ 14.2VRated @ 4 ohms (bridged) - 150W x 2 @ 14.4VMeasured wattage at 4 ohms (bridged) - 192W x 2 @ 13.93VRated "Max Output Power" - 600WMeasured Dynamic RMS Power at 2 ohms (bridged) - 374+357 = 731W !!See my full video review on YouTube under the channel for BigDWiz.I also tested this little amp in the 3 channel mode, using 2 channels for 6.5" coaxials and the other two channels bridged to a single 10" 4 ohm MTX Blue Thunder subwoofer. The amp sounded very clean and dynamic. I was playing back FLAC files through my Kenwood KMM-BT312U head unit in my toolbox boombox. I bought this amp to use in the toolbox boombox, was so happy with the performance, I also ordered the matching 300W monoblock, the KDC-M3001. I'll test this when it comes and report the results.I don't have reliability statistics as this amp is relatively new to the market. I can say compared to similar sized amps such as the Rockford Fosgate PBR-300x4, the Kenwood eats it's lunch. The PBR isn't bridgeable (also not 2 ohm stable) and isn't nearly as flexible as the Kenwood.It is my opinion Kenwood has set the bar here for the mini amps. At about the same dimensions (except thickness) as my iPhone 6 plus, it's simply incredible this little amp can put out over 700W dynamically! Great job Kenwood!

This mini amplifier is great! While it may be small in size, it has plenty of features. The switchable and variable high/low pass filters on both pairs of channels are great. In my application, which has the amplifier tucked away inside a center console, it still barely gets warm (though this is the cold part of the year - so I expect that's part of it). The sound is clean and clear and is more than enough for any non-competition system. I'm running my two front speakers on the A channels of this amplifier (HPF at 80 Hz) and running a single 4 ohm subwoofer off the bridged B channels of the amplifier. It's more than enough for my subwoofer, which is an 8" high excursion unit in a small sealed box. My only complaint about this amplifier is a minor one. It's somewhat tricky to adjust the gains unless you have a good view and access to that end of the amplifier. Using a small screwdriver it's very tricky to find the gain potentiometer knobs since they are quite recessed into the unit and much smaller than the hole for the screwdriver. It would be better if the knobs were either flush with the hole (and the same size), or if they stuck out of the unit instead of being recessed. However, once you get them set it's not like you will be adjusting them all the time. My only other wish would be that all the wiring connections be on the same side of the amplifier, instead of having the RCA inputs on the opposite side from the outputs and power connections. However, I believe it's probably not possible with this small an amplifier - or they would have to be on the long side of the unit, which also wouldn't work in my installation.All in all, for the price and size of this unit, it's an amazing amplifier. Back when I first got into car stereo many moons ago (early 1990s) an amplifier with this performance would be 4+ times the size of this unit and 2-3+ times the price. This unit gives all kinds of possibilities for stealth installations and at the price, running a 50w channel for each driver in a component system, if that's your thing.

I used the amp under the steering column in my 04 Jeep Wrangler TJ.It fits great under there mounted up with a cutting board with tons of rooms to spare. It currently powers a 6.5 inch kicker subwoofer and has more than that sub could ever ask for and sounds excellent pleased with the setup so far and this thing really has my jeep sounding great .

I have a 2006 Colorado and decided to upgrade the sound system. I used JBL's Concert 601CF and a Kenwood DPX792BH deck. Ater installing the deck, I realized the system did not have enough juice to move the speakers. So after looking for a while I decided to give this amp a try. I needed something small to fit in the dash in order to save time on the install. The amp did not disappoint. It fit right at the base below the AC controls which helps to keep it cool. Also, it moves the speakers pretty good. I have to wait to see if it will last, but so far is a good purchase. I am giving it 4 stars because quality remains in question.

I don't know why Amazon lists this as "Kenwood 22154656" instead of its actual model number of KAC-M3004, but if you're curious, that's what it is. I'm extremely happy with this amp. I also own a KAC-M1804, and I'm not sure whether these are concurrent models or the 3004 replaces the 1804 or what, but if space isn't your *sole* concern I would highly recommend the slightly larger M3004 - it's something like 1/2" in each direction bigger, and what you get for that is more power, bridging, filters, variable crossovers, a 2 ohm stability. It's a lot of extra features for a small price and size increase. It works perfectly in my 2002 Saab Viggen in place of the factory amp, and since it has built-in HPF/LPF, I'm able to drive the door woofers in LPF mode (as the factory did) and the rear full-range speakers at the same time, with the same tiny amp. Huge improvement in sound for something like a 30 minute install. I guess bear in mind I'm listening to MP3s in a convertible, so I won't comment on its audiophile qualities, but it seems very good especially for a Class D amp. I was having a rough time finding an amp that did exactly what I needed it to (that is, be small, reasonably powerful, and have a built-in LPF) so I was happy to find this. There's a good chance I'll buy another one of these soon.

This amplifier is excellent. It is not differential so it grounds through the case. Just a heads up. Sounds fantastic. I have two.

Very pleased with this unit. I bought it for my Miata. It’s plenty loud enough. This is essentially two amps in one box that can be bridged. 4 CH, 2+Sub, or 1 bridged mono.With the four channels you can adjust the gain on each one, so you can set the Fade front to rear. (My setup)Each channel also has adjustable low or high pass filters, so if you’ve got a small set of tweeters or in seat speakers, you can roll off some lows. Filters are low/off/high selectable for both sides/Chanel pairs of the amp.Easy setup out of the box. Standard car amp stuff. Would recommend.

Bought to replace a 40 year old mono amp. Smaller than the one that I had and more powerful. Easy install, great compact size for easy fitment. Seems powerful enough for my use.

Great little amp for my motorcycle. It gave me that little more volume I needed on the highway.

I have it running two 6x9's and 2 5.25" speakers in my dash. It pulls signal from the kenwood deck, then into an equalizer, then into the amp. Good price, great size, good power for what it is, and easy install. Could easily mount in a side by side or boat or whatever really. Even a motorcycle.
