6-Channel Full Range Class D Amplifier

Power your entire system with precision and durability using the Diamond Audio MOTORSPORT Series 6-Channel Full Range Class D Amplifier. Designed for marine, motorcycle, UTV, ATV, and powersports audio systems, this 6-channel amplifier delivers powerful, clean sound while standing up to the harshest outdoor conditions.

Engineered with advanced full-range Class D digital technology, the Diamond Audio MOTORSPORT 6-channel amplifier provides impressive output with 90W x 4 + 150W x 2 at 4 ohms and 150W x 4 + 250W x 2 at 2 ohms. For higher power applications, it supports bridged operation up to 300W x 2 and 500W x 1 (channels 5/6 bridged), making it ideal for powering full-range speakers and subwoofers from a single amplifier.

Built for extreme environments, this water-resistant amplifier features conformal-coated multi-layer circuit boards, ensuring long-lasting reliability in wet, dusty, and rugged conditions. The anodized extruded aluminum heat sink enhances cooling performance, keeping the amplifier operating efficiently even during extended play.

The Diamond Audio MOTORSPORT amplifier also incorporates balanced differential inputs for noise-free signal transmission and a DirectFET power MOSFET output stage for efficient, high-quality audio performance. With variable high-pass (40Hz–400Hz) and low-pass (30Hz–300Hz) crossovers, along with phase control, this versatile multi-channel amplifier allows precise system tuning for optimal sound.

Installation is simplified with selectable REM, VOX, and DC turn-on modes, making it compatible with factory and aftermarket head units. Additional features such as top-mounted controls, output clip indicators, an illuminated logo, and an included bass remote control provide convenience and system control.
