Image is for illustrative purposes only
The KENWOOD KAC-M1814 is a compact 4-channel Class-D amplifier designed for multi-application use in cars, marine vessels, and motorsports. With 400W peak power, it delivers louder volume with low noise.

Its robust design includes plastic-covered connectors to protect against water and dust, while a conformal coating provides vibration resistance and prevents PCB rusting, ensuring durability in harsh environments.

Connectivity is versatile, offering RCA Line-In terminals or Speaker Level Input with Signal Sensing Turn-on, allowing connection to any type of receiver. It features A.ch and/or B.ch Filter Frequency Control and a Filter Switch to apply HPF / OFF / LPF. The amplifier also supports bridgeable connections, and its separated pre-amp and power-amp sections reduce radiation noise for cleaner sound.
