Description


2-Channel Amplified Motorsport Performance

Powering a comprehensive outdoor soundstage requires an amplifier capable of driving multiple heavy-duty speakers without aggressively draining your vehicle's battery. The Diamond Audio HXM800.4D rises to the challenge as a highly versatile 4-channel Class-D workhorse specifically engineered for marine and powersports applications. By leveraging a high-efficiency IR digital chipset, this robust powerplant effortlessly pushes 120 watts RMS to four channels at 4 ohms, and 200 watts per channel when wired to a 2-ohm load. For those requiring even more extreme output, you can easily bridge the channels to send a punishing 400 watts to a pair of massive wake tower enclosures, ensuring your playlist completely dominates howling winds and aggressive engine noise.

Delivering raw volume means nothing if the resulting audio sounds harsh or distorted at peak levels. To guarantee exceptional, studio-quality acoustic reproduction, this MOTORSPORT series unit incorporates balanced differential inputs that actively reject annoying alternator whine and unwanted electrical interference right from the source. Getting your system perfectly dialed in is remarkably straightforward thanks to top-mounted controls, featuring fully variable high-pass and low-pass crossovers stretching from 40Hz to 400Hz. Paired with adjustable phase control and integrated output clip indicators, you gain immediate, precise command over your entire frequency spectrum, eliminating tuning guesswork and protecting your expensive speakers from clipping.

Subjecting your sensitive electronics to brutal open-water and off-road environments demands uncompromising structural armor. Manufactured with conformal-coated, multi-layer circuit boards, this rugged amplifier fiercely repels heavy moisture, corrosive salt spray, and thick trail dust. The internal circuitry is heavily guarded by an extruded, anodized aluminum heat sink that actively disperses thermal buildup during marathon listening sessions under the intense summer sun. Measuring just 9.3" long and 1.75" thick, this ultra-compact powerhouse easily tucks into cramped boat storage compartments or tight side-by-side consoles, providing a completely weather-defying foundation for your next outdoor adventure.
