Description


2-Channel Amplified Motorsport Performance

Driving high-performance audio across wide-open water or dusty trails requires an amplifier that delivers brutal, continuous power without overwhelming your vehicle's charging system. Diamond Audio HXM800.2D is an aggressively efficient 2-channel Class-D workhorse engineered to inject massive volume into any marine or powersports soundstage. By utilizing an advanced IR digital chipset and a robust PWM power supply, this compact unit effortlessly pushes 300 watts RMS per channel at 4 ohms and 400 watts at 2 ohms. For those demanding absolute maximum output, you can bridge the channels to send a staggering 800 watts to a heavy-duty wake tower setup or a dedicated marine subwoofer, ensuring your music completely dominates background engine noise.

Securing immense volume means nothing if the resulting sound is distorted or fatiguing to the ears. To guarantee studio-level clarity at full throttle, this MOTORSPORT series amplifier incorporates a DirectFET output stage and balanced differential inputs that actively reject alternator whine and unwanted electrical interference. Dialing in a perfectly tuned acoustic profile is fast and intuitive thanks to fully variable high-pass and low-pass crossovers ranging from 40Hz to 400Hz. Paired with convenient top-mounted controls, adjustable phase settings, and integrated output clip indicators, you gain precise, tactile command over your entire frequency range to prevent speaker damage and maximize sonic accuracy.

Exposing your sensitive audio electronics to harsh outdoor environments demands serious structural armor. Built specifically for extreme abuse, this 2-channel amplifier features conformal-coated, multi-layer circuit boards that aggressively repel heavy moisture, salt spray, and thick trail dust. The rugged internal components are protected by an extruded, anodized aluminum heat sink designed to actively disperse thermal buildup during marathon listening sessions. Measuring just 9.74" long and 1.75" thick, this ultra-slim powerhouse slides effortlessly into tight motorcycle fairings, boat compartments, or under side-by-side seats, providing a stealthy and completely weather-defying foundation for your next adventure.
