Unleash extreme bass performance with the Diamond Audio MOTORSPORT Series 1-Channel Class D Monoblock Amplifier, engineered for high-output systems that demand power, precision, and durability. Designed for marine audio, motorcycles, UTVs, ATVs, and powersports applications, this high power monoblock amplifier delivers exceptional performance in the toughest environments.

Built with advanced full-range Class D digital technology, the Diamond Audio MOTORSPORT monoblock amplifier produces massive output with 1200W RMS at 1 ohm, 850W at 2 ohms, and 550W at 4 ohms, making it ideal for driving high-performance subwoofers. Whether you're upgrading your marine subwoofer system or building a powerful off-road audio setup, this subwoofer amplifier delivers deep, tight, and controlled bass.

Designed for durability, this water-resistant amplifier features conformal-coated multi-layer circuit boards, protecting against moisture, dust, and harsh outdoor conditions. The anodized extruded aluminum heat sink ensures superior thermal performance, keeping the amplifier cool even under heavy load.

The Diamond Audio MOTORSPORT amplifier also includes balanced differential inputs for noise-free signal transmission and a DirectFET power MOSFET output stage for efficient, high-quality performance. With a variable low-pass crossover (30Hz–300Hz), subsonic filter (10Hz–55Hz), and phase control, this versatile monoblock amplifier allows precise tuning for optimal bass response.

Installation is seamless with selectable REM, VOX, and DC turn-on modes, ensuring compatibility with factory and aftermarket systems. Additional features such as output clip indicators, top-mounted controls, and an included bass remote control provide convenience and real-time system adjustment.
