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

This amp is the perfect size to install on a Harley touring motorcycle, it fits nicely in the fairing. Install was very easy and straightforward. My head unit is a SoundStream Reserve HDHU 14+, Kenwood speakers. The amp does not draw a lot of power so I tapped the power and ground leading to the stereo. I will run cables to the battery later. I bridged the amp to two channels since I only have two front speakers on by Harley. Amp provides great power and sound.

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 is the second of these handy little units I've installed. Made a huge difference on my 05 Road King and did the same on my 16 FLHTKL. Didn't realize I was going to have to pull the whole fairing apart to swap speakers and all THAT, but if you're going to do it.... The biggest issue I had was the splicing and soldering of the individual wires for the speakers. I was going from a Soundstream Reserve HDHU14+ into the amp and then into the actual speakers. Was able to take my RCA outputs directly from the HU into the amp and then splice the output wires directly into the harness between the Soundstream and the stock HD audio harness. Thankfully all wire colors matched up to simplify things. Added some JBL speakers all the way around. On this install, I did need to patch in the Power control (blue) wire to alert the amp it was time to turn on. I wired it into the heated handgrips so it would be a switched control. On my Road King install, the input strength automatically kicked on the amp. With the low-power RCA inputs on this FLHTKL install, the amp needed a heads-up. Was originally not happy as the sound was real muddy in spite of the more powerful amp and speakers. NOTE: If you have this problem, turn OFF your equalizer settings. You should have plenty of power to drive those speakers and not really need the equalizer. Besides, as in my setup, with 6.5" speakers, you're NOT going to really be thumping any bass - no matter HOW much you try to pump it up. IMMEDIATELY became much cleaner and REALLY kicked! Again, super happy with THIS install. It may not satisfy the audiophiles out there, but for me rolling down the road and wanting to hear some Molly Hatchet at highway speeds? It's just the thing. VERY SATISFIED CUSTOMER!

Used on a boat with a fresh ground, it still had some noise at silent, but at volume, speakers (Polk MM652) are loud and clear. No true complaints.

Perfect fit. Great quality. Great value.

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.

Defective on arrival. Would not power on.

Running this at 4 ohms. Had it running at 2ohms and didn’t like the sound quality. Plenty of power and clarity at 4ohms. Running all Kenwood Excelon speakers off of this amp. Easy to install and set the gains. Small and overheated once at 2ohms but hasn’t shut down at 4ohms. Have it in my glove box. Great amp for the money.

Muy bien sonido y una potencia aceptable. El amplificador tiene un tamaño pequeño adaptable a cualquier sitio. Lo único que destacaría en su contra es que los cables de conexión se quedan cortos. En mi caso me los tuvieron que sustituir por otros más largos, pero en general estoy satisfecho. Buen sonido Kenwood y calidad.

Funziona da dio. Secondo me un buon acquisto

Surprisingly good for the price. I put this in my boat and what a difference! Much Louder, higher quality sound and adds a decent amount of thump for a 6" round x 4 channel set up. Exactly what I was looking for. Ideal for your mid-high range speakers imo.

Had a short right out of the box, blew a couple of my speakers, was made to have to contact seller for return, seller is very horrible to deal with

I've ordered several of these for a stereo kit that I build for an obscure vehicle, and I have been impressed time after time with these units. The 4 channel setup is perfect for powering any speaker set you want to hook it to, full range of gains on volume control and bass, and the price is just right.
