Infinity designed the latest Kappa Series amplifiers to deliver increased efficiency and performance from an extremely compact package. These slim powerhouses stand only 1-3⁄4" tall, so they'll fit easily in spaces where other amps just won't go. And efficient heat dissipation means these amps won't get too hot in tight quarters.

The Kappa One mono amplifier makes an ideal match for your high-performance Kappa sub, dispensing up to 800 watts of clean power. The amp's Class-D design generates less heat, eliminating the need for large heatsinks. Non-stop Thermal Protection circuitry adjusts the amp's output so it runs cool, no matter how hard you push your system. Balanced speaker-and preamp-level inputs reject engine whine and other noise from your car's electrical system.

The unique detachable power/ground plug lets you connect and disconnect large-gauge power cables in one easy step. The amp's Dynamic Bass Optimization circuit lets you filter and shape the bass for the best possible performance from your sub and enclosure.
