Diamond Audio MICRO84U 125W RMS 4-Channel Full Range Class D Powersports Amplifier

Diamond Audio MICRO84U 4-Channel Full Range Class D Amplifier

The Diamond Audio MICRO84U is a high-performance power solution designed for drivers who need elite sound in limited spaces. Built on the legacy of the popular MICRO series, this "big-brother" 4-channel amplifier delivers significantly more power and efficiency. With its all-weather architecture and versatile Class D design, it provides a rugged, high-fidelity foundation for motorcycles, marine vessels, and compact vehicle installations.

Compact Power Architecture:

Achieving professional-grade audio shouldn't require sacrificing your vehicle's storage or fairing space. The MICRO84U utilizes a sleek, ultra-compact platform designed to fit into tight compartments where traditional amplifiers cannot. Its uniform dimensions allow for a clean, integrated installation, ensuring that even the most restricted setups can benefit from a massive increase in volume and clarity.

High-Fidelity Signal Integrity:

Driving at highway speeds or through open water requires an audio system that can maintain precision under pressure. This full-range Class D powerhouse delivers a relentless 85 Watts RMS x 4 at 4 ohms, ensuring your music remains sharp and distortion-free. By utilizing an advanced digital circuitry layout, the amplifier captures the nuances of high-resolution files, providing a vivid and immersive soundstage that cuts through environmental noise with ease.

Advanced System Integration:

True performance is defined by how well a component adapts to your existing electronics. The MICRO84U features a wide 0.2V to 10V input sensitivity, allowing it to pair seamlessly with both factory and aftermarket head units. With its variable 12dB per octave crossovers (40Hz–400Hz), you have the professional tools needed to precisely route frequencies to your speakers or subwoofers, ensuring a perfectly balanced and protected audio array.

Weather-Hardened Endurance Core:

Life in outdoor environments demands a level of durability that standard car audio components cannot provide. This amplifier is conformal-coated to protect internal circuits from moisture, dust, and temperature cycles, making it a ruggedized choice for all-weather applications. Engineered from the ground up for resilience, the MICRO84U acts as a dependable workhorse that performs at its peak whether you're on the trail, the road, or the water.
