Transform the audio experience in your marine vessel, UTV, or motorcycle with the Diamond Audio HXM800.4D, a robust 4-channel amplifier from their premium MOTORSPORT Series. Engineered to deliver exceptional, audiophile-grade sound quality while enduring the toughest outdoor elements, this ultra-compact, full-range Class D amplifier generates an impressive 800 watts of total RMS power. Pushing 200 watts per channel at 2 ohms, 120 watts per channel at 4 ohms, or bridgeable to a massive 400 watts x 2 at 4 ohms, it provides incredible versatility. Whether you are driving four high-performance wake tower speakers, a powerful array of motorcycle fairing components, or bridging it to run a pair of subwoofers, the HXM800.4D delivers pristine, dynamic sound in any mobile audio application.
Designed for maximum durability and thermal efficiency, the HXM800.4D features a water-resistant, conformal-coated multi-layer glass epoxy circuit board that prevents damage and corrosion from moisture, dust, and salt. Under the hood, it utilizes advanced full-range digital Class D technology paired with a DirectFET power MOSFET output stage for extreme efficiency and low heat generation, all safely housed within an anodized extruded aluminum heat sink. It guarantees noise-free operation via balanced differential inputs, rejecting the engine hum and electrical interference commonly found in powersports applications. With precise top-mounted controls, output clip indicators for perfect tuning, and a selectable 3-option auto turn-on mode, integrating this powerhouse into your outdoor vehicle is incredibly straightforward.
