DII1400.5 - 1,400 Watts, Class-D, 5-channel Amplifier

The DII1400.5 packs five channels of Class-D amplification into a 9.7" x 5.4" footprint, delivering 160W x 4 at 2 ohms plus 800W x 1 on the mono channel — enough to run a full system from a single, compact unit. Controls are top-mounted beneath a protective cover, keeping adjustments accessible without sacrificing a clean install.

• 5-channel Class-D design: Four full-range channels and a dedicated mono channel handle speakers and subwoofer from one amplifier.
• Flexible power output: 160W x 4 at 2 ohms, 100W x 4 at 4 ohms, and 800W x 1 mono at 2 ohms; 4-ohm bridging available on the stereo channels (320W x 2).
• 2/4 channel input switching: Compatible with head units that have limited RCA outputs, with RCA pass-through for daisy-chaining.
• Three turn-on modes: REM, VOX, and DC offset detection for versatile installation scenarios.
• Mono channel tuning: Includes 0–12 dB bass boost, 10–50 Hz subsonic filter, and a remote bass control output.
• 4-way protection circuit: Guards against thermal, voltage, and speaker DC faults, with clip detection LEDs visible at 1% THD.
