DII700.4 - Ultra Compact Full Range Class-D 4-channel Car Audio Amplifier, Max 1,400 Watts, 2-4 OHM Stable, Bridgeable

The DII700.4 packs four channels of Class-D amplification into a footprint just over six inches long, making it a practical choice for builds where space is limited but output isn't optional. With 160W x 4 at 2 ohms or 340W x 2 bridged, it covers both full-range and component speaker configurations from a single unit. Controls are top-mounted under a protective cover, keeping adjustments accessible without removing the amp.

• Compact Class-D design: Measures 6.3" x 5.4" x 2.1" — engineered for tight installs without sacrificing channel count.
• Flexible power output: 110W x 4 at 4 ohms, 160W x 4 at 2 ohms, or 340W x 2 bridged at 4 ohms.
• Three turn-on modes: Remote (REM), signal-sensing (VOX), and DC offset — adapts to vehicles without a dedicated remote wire.
• 2/4 channel input switch: Accepts stereo or four-channel source signals without additional adapters.
• Full crossover control: Independent HPF and LPF, each adjustable from 30Hz to 300Hz.
• RCA pass-through outputs: Daisy-chain additional amplifiers without a signal splitter.
• 4-way protection circuit: Guards against thermal, voltage, and speaker DC faults.
