DII3300.1 - 3300 Watts Class-D Mono Amplifier

The DII3300.1 delivers 3300 watts at 1 ohm in a chassis that measures under 10 inches long — compact enough to fit where full-size mono blocks won't, without compromising on output. Built around Recoil's proprietary Class-D topology, it maintains constant power across 2 and 4 ohm loads, making it a practical choice for a range of subwoofer configurations. Controls are top-mounted beneath a protective cover, keeping adjustments accessible after installation.

• 3300W RMS at 1 ohm — constant power output also rated at 2050W (2Ω) and 1000W (4Ω)
• Proprietary Class-D technology with a frequency response extending to 270 kHz and THD+N under 0.12%
• Three turn-on modes — REM, VOX, and DC — for flexible installation scenarios
• Top-mounted control panel with bass boost (0–16dB), LPF (44–270Hz), and HPF (10–54Hz) crossover adjustment
• 2/4 channel input switch with both low-level (1.1–11V) and high-level (0.2–2.5V) input sensitivity ranges
• RCA pass-through outputs for daisy-chaining additional amplifiers
• Clip detection LEDs and 4-way protection circuit covering thermal, voltage, and speaker DC faults
