1-Channel Class D Monoblock Amplifier
Black Diamond’s DIA-P1000X1D delivers 380W RMS at 4 ohms, stepping up to 600W RMS at 2 ohms, and 1000W RMS at 1 ohm. This amp brings clean, distortion-free power perfect for any subwoofer setup.
Precise Bass Control
Gain control is adjustable from 0.2 to 6 volts input sensitivity, letting you match your head unit perfectly. The bass boost switch offers 0, 6, or 12 decibels of added punch.

The low-pass filter is adjustable between 40 and 180 hertz to fine-tune your bass output with tight, clear sound.
