The DII1000.1 is a compact mono block amplifier built around Recoil's proprietary Class-D topology, delivering up to 1,100W RMS at 1 ohm from a chassis that measures under 8 inches in length. Designed for subwoofer applications, its multi-impedance constant power output makes it adaptable across a range of woofer configurations without sacrificing efficiency. Controls are top-mounted beneath a protective cover, keeping adjustments accessible without cluttering the install.

• Multi-impedance constant power: Stable output at 1, 2, and 4 ohm loads — 1,100W, 700W, and 370W RMS respectively at 14.4V.
• Flexible turn-on modes: Supports REM, VOX, and DC signal detection for compatibility across head unit configurations.
• Adjustable bass boost and crossover: 0–12dB bass boost, LPF from 80Hz–20kHz, and HPF from 10Hz–80Hz with optional bass remote control.
• Clip detection LEDs: Visual clip indication triggers at 1% THD, allowing real-time gain monitoring.
• RCA pass-through outputs: Enables clean signal daisy-chaining to additional amplifiers.
• 2/4 channel input switching: Accepts both 2- and 4-channel input signals for broader source compatibility.
• 4-way protection circuit: Guards against thermal, voltage, and speaker DC fault conditions.
