Diamond Audio 4-Channel MICROV2 Series Full Range Class D Amplifier - MICRO4V2

Diamond Audio MICRO4V2 4-Channel Full Range Class D Amplifier

Power your full speaker system with precision and efficiency using the Diamond Audio MICRO4V2 4-Channel Full Range Class D Amplifier. Built for car, motorcycle, marine, and powersports audio systems, the MICRO4V2 delivers clean, dynamic output in an ultra-compact chassis that installs just about anywhere.

Running full-range Class D topology, this amp puts out 80W x 4 @ 4Ω, 150W x 4 @ 2Ω, and 300W x 2 bridged @ 4Ω — plenty of headroom for a full speaker setup or a bridged subwoofer channel. Balanced differential inputs keep the signal clean and noise-free, while Advanced Rollback and Thermal Protection ensures the amp keeps running without shutdown under sustained load.

The high-density aluminum alloy chassis handles heat dissipation efficiently while keeping the footprint tight. Tune your system with selectable LPF / FLAT / HPF crossovers, a 40–400Hz adjustable crossover filter (12dB slope), and 12dB bass boost @ 45Hz. Selectable REM, VOX, and DC turn-on modes plus 2CH / 4CH input options make integration with factory or aftermarket head units straightforward.
