Product Description

KAC-M1814

Kenwood KAC-M1814 - Power your speakers on land or sea

Kenwood's super-compact KAC-M1814 will add new clarity and impact to the basic sound system of almost any kind of vehicle on land or water, and it'll fit in a lot of places when space is tight. This marine-rated 4-channel amp will pump up your audio system with 45 watts RMS per channel — that's more than twice the power of most car stereos or marine receivers. The amp uses plastic covers to protect its connections and features a conformal-coated circuit board that keeps out moisture and salt, so the party won't stop just because of a little wetness.

This amp was the perfect size and fit for my boat’s stereo system. Sound quality is excellent and the install was a breeze.

For the small size of this unit, it really puts out some decent power. Very happy with the sound quality also. Driving 6.5" marine speakers

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!

5.0 out of 5 stars Great Amp
Reviewed in the United States on March 2, 2023
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.
