Deliver deep, powerful bass in any environment with the Diamond Audio MOTORSPORT Series 1-Channel Class D Monoblock Amplifier. Engineered for high-performance audio systems, this monoblock amplifier is designed to provide exceptional output and reliability for marine, motorcycle, UTV, ATV, and powersports applications.

Built with advanced full-range Class D digital technology, the Diamond Audio MOTORSPORT monoblock amplifier produces impressive power with 800W at 1 ohm, 550W at 2 ohms, and 350W at 4 ohms RMS, making it ideal for driving subwoofers with tight, controlled, and impactful bass. Whether you're upgrading your marine audio system or building a high-output powersports sound system, this high power subwoofer amplifier delivers consistent performance.

Designed for extreme conditions, this water-resistant amplifier features conformal-coated multi-layer circuit boards, protecting internal components from moisture, dust, and harsh environments. The anodized extruded aluminum heat sink ensures superior thermal performance, keeping the amplifier cool during extended use.

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

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