Kicker KMA600.6 6-Channel Marine Amplifier

The Kicker KMA600.6 is a versatile 6-channel marine amplifier designed to power multiple zones across your boat with clean, efficient output. Built for marine environments, it delivers strong performance, flexible tuning, and reliable durability, making it ideal for complete boat audio system upgrades.

Using a high-efficiency Class D design, the KMA600.6 produces up to 50 watts RMS per channel at 4 ohms (or up to 100 watts RMS per channel at 2 ohms), with the ability to bridge channels for up to 200 watts RMS across three channels. This makes it ideal for running multiple speaker zones or combining channels for higher-output applications such as subwoofers or larger marine speakers.

With up to 750 watts of dynamic power, this amplifier is capable of delivering strong, clear sound across the entire vessel. Three-zone capability allows for flexible system design, ensuring balanced audio distribution from bow to stern.

Engineered for marine conditions, the KMA600.6 features a conformal-coated circuit board, stainless-steel hardware, and ABYC/NMMA-compliant power connections to ensure long-term reliability in wet, high-vibration environments.

Advanced tuning features include a variable 12dB crossover network and KickEQ™ bass boost on channel 3, allowing fine control over system response and low-frequency performance. This ensures your audio system can be tuned for clarity, impact, and balance across all listening zones.
