Also in the AIR range: the AIR-D1 mono subwoofer amplifier and the AIR-D4 4-channel amplifier.

Option Audio AIR-D6 6-channel amplifier

Maximum power for the entire system: Six channels rated at 6 × 95W/150W RMS (4/2 ohms) let you run a front system, rear speakers and a subwoofer from a single unit.

Ultra-compact micro design: Despite its output, the AIR-D6 is extremely small. The space-saving housing fits behind the dashboard, in the glove compartment or under a seat.

OEM integration: High-level inputs with auto turn-on mean the AIR-D6 works directly with factory head units that have no RCA outputs. It detects the audio signal automatically and powers on without a separate remote cable.

Flexible configuration: Run all six channels for a full speaker setup, or bridge channels to deliver 300W RMS at 4 ohms for demanding components or a subwoofer. Integrated high-pass and low-pass filters (40Hz–400Hz) allow precise frequency separation.

Efficient Class D technology: The digital circuit delivers high efficiency with minimal heat generation. 2-ohm stability allows a wide range of speaker combinations.
