When your system requires more power without the added complexity of DSP, ARC Audio Nighthawk responds to this challenge. Designed as the ideal complement to ARC Audio's DSP-enabled amplifiers, such as the Blackbird, and compatible with current and future ARC models with DSP - Nighthawk delivers exceptional output power, crystal sound quality and installation flexibility, all in a tailored enclosure and consistent industrial design for seamless system integration.

This fully bridgeable, high-end two-channel Class D amplifier generates up to 800 watts in bridge mode at 4 Ω mono (according to CTA-2006), offering low distortion levels comparable to much more expensive reference-grade amplifiers. Whether you're driving subwoofers, midrange speakers or full-range components in high-efficiency or high-demand systems, Nighthawk delivers spare power, clarity and control, even under the most demanding conditions.

With balanced differential inputs, switchable stereo/mono configuration and compatibility with the ARC high-current speaker connection system, the Nighthawk works equally well in motorbike, marine installations, powersport environments and audiophile-grade car audio systems.

The ARC philosophy of 'promise less, deliver more' is on full display here. Although officially the power quoted is 800 W in the bridge, the actual power in practical conditions far exceeds this value - giving installers and competitors the confidence to go further without compromise. Developed with practical use in mind, it offers full-band operation from 10 Hz to 32 kHzmaintains thermal stability in the from -20°C to +82°C and supports voltages compatible with start-stop systems up to 4,6 V.

Whether you are expanding an ARC DSP-based system or building a powerful stand-alone kit - the Nighthawk is designed to enhance the quality of your sound: clear, powerful and professional.
