Kenwood KAC-M1814 Compact 4-Channel Marine Amplifier
Big Power. Small Footprint. Ready for Any Adventure.
The Kenwood KAC-M1814 is a powerhouse in a pint-sized package. Designed for those who need high-quality audio in space-constrained environments, this compact Class-D amplifier is the perfect addition to your boat, ATV, motorcycle, or car. Despite its small size, it delivers a massive boost in volume and clarity compared to a standard head unit.
Rugged & Multi-Application Design
-
Conformal Coating: The internal circuit board is treated with a specialized protective coating, shielding the electronics from moisture, salt air, and corrosion—essential for marine and outdoor use.
-
Sealed Protection: Features plastic-covered connectors to keep out dust and water, ensuring long-term reliability in harsh environments.
-
Vibration Resistant: Built to withstand the constant movement and jolts of waves or off-road trails.
Powerful & Flexible Performance
-
4-Channel Class-D Technology: Efficient digital amplification provides 45W RMS per channel (at 4 ohms), more than doubling the power of most standard stereos for cleaner, louder sound.
-
Bridgeable Output: Need more punch for a pair of high-end speakers? Bridge the amplifier to 2-channel mode to deliver 90W RMS x 2.
-
2-Ohm Stability: Capable of driving lower impedance loads, giving you more flexibility when choosing and wiring your speakers.
Smart Integration
-
Signal Sensing Turn-On: No need for a messy remote turn-on wire. The amp automatically detects when your receiver is playing music and powers itself up.
-
Versatile Inputs: Equipped with both RCA and speaker-level inputs, allowing it to connect seamlessly to both aftermarket marine receivers and factory-installed systems.
-
Independent Audio Tuning: Features independent gain controls and selectable High-Pass/Low-Pass filters (50Hz–200Hz) for both the front and rear channels, letting you customize the sound to your specific speakers.
