The BH-M1000 is a compact Class D monoblock built specifically to drive subwoofers. Class D topology means 80–85% efficiency — it runs cool and won't drain your alternator the way old school amps would.
Built-in subsonic filter at 15–55 Hz protects your sub from frequencies it can't reproduce cleanly. Low-pass crossover adjustable 50–250 Hz.
