Black Diamond DIA-P1800X4D
Class D 4-Channel Full Range Amplifier

The DIA-P1800X4D delivers 200W RMS per channel at 4 ohms and increases to 320W RMS per channel at 2 ohms. When bridged, it pushes 600W RMS per channel at 4 ohms. Its frequency response spans from 20Hz to 20kHz, producing clear sound with only about 1% distortion.

Precise Sound Control
Input gain adjusts from 0.2 to 6 volts, and you can select full, low-pass, or high-pass crossover between 40Hz and 4kHz. This flexibility lets you tailor the sound precisely to your system’s needs.

Built for Endurance
This amplifier features thermal, overload, DC output, short circuit, voltage input, and clipping protections: ensuring stable operation. It uses 4 gauge power wiring and requires a 120A fuse for optimal safety.

Compact and Installation Friendly
The DIA-P1800X4D measures 9.64 inches long, 6.1 inches wide, and 2 inches tall. Its 8.66-inch heatsink efficiently dissipates heat for long-lasting performance.
