Diamond Audio MICRO1V2 1-Channel MICROV2 Series Monoblock Class D Car Amplifier

Diamond Audio MICRO1V2

The Diamond Audio MICROV2 1-Channel Monoblock Class D Amplifier, engineered for efficiency and performance, this monoblock car audio amplifier is designed to drive subwoofers with precision, making it ideal for car audio, marine, motorcycle, and powersports systems where space and reliability matter.

Built using ultra-efficient full-range Class D topology, the Diamond Audio MICROV2 monoblock amplifier produces impressive power in a small chassis, delivering 500W x 1 at 1 ohm, 300W x 1 at 2 ohms, and 175W x 1 at 4 ohms RMS. This makes it the perfect subwoofer amplifier for tight, impactful bass and consistent performance across a wide range of audio setups.

The MICROV2 Class D amplifier features an advanced Direct FET power MOSFET output stage, ensuring clean, efficient power delivery with minimal distortion. Combined with balanced differential inputs, this high-performance amplifier provides noise-free signal transmission, even in complex installations.

Designed for durability, the Diamond Audio MICROV2 amplifier includes advanced Rollback and Thermal Protection, preventing overheating and ensuring uninterrupted playback. Its high-density aluminum alloy chassis improves heat dissipation while maintaining an ultra-compact design for flexible installation in tight spaces.

For precise tuning, the MICROV2 monoblock amplifier includes a 40–400Hz low-pass crossover (24dB slope), Diamond bass boost EQ (12dB @ 45Hz), and adjustable input sensitivity (0.2–10V). The included remote bass knob allows real-time control of subwoofer output, giving you full command of your bass performance. Installation is seamless with selectable REM, VOX, and DC turn-on modes, ensuring compatibility with factory and aftermarket head units.
