2-Channel Full Range Class D Amplifier

Power your outdoor audio system with precision and durability using the Diamond Audio MOTORSPORT Series 2-Channel Full Range Class D Amplifier. Engineered for extreme environments, this high power 2-channel amplifier delivers exceptional sound quality for marine audio, motorcycle, UTV, ATV, and powersports systems.

Built with advanced full-range Class D digital technology, the Diamond Audio MOTORSPORT amplifier produces impressive output with 300W x 2 at 4 ohms and 400W x 2 at 2 ohms, delivering clean, dynamic sound across the entire frequency range. For more demanding applications, the amplifier can be bridged to 800W x 1 at 4 ohms, making it perfect for powering subwoofers or high-output speaker systems.

Designed to handle harsh conditions, this water-resistant amplifier features conformal-coated multi-layer circuit boards, ensuring reliable performance in wet, dusty, and rugged environments. The anodized extruded aluminum heat sink enhances thermal performance, keeping the amplifier cool even under heavy load.

The Diamond Audio MOTORSPORT 2-channel amplifier also incorporates balanced differential inputs for noise-free operation and a DirectFET power MOSFET output stage for efficient, high-quality sound reproduction. With fully variable high-pass and low-pass crossovers (40Hz400Hz) and phase control, this versatile car and marine amplifier allows precise system tuning for optimal audio performance.

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