Hifonics HCM-1200.1D 1200 Watt Mono Amplifier Mini 1 Ohm Class D Car Stereo Amp

The Hifonics HCM-1200.1D is a COLOSSUS MINI mono block amplifier that puts 1200W into a chassis measuring 11.1in x 5.28in x 2.72in. The footprint is the point: it mounts under a motorcycle seat, inside a UTV dash, or behind a car seat where a full-size amplifier will not go.

Power ratings are 1 x 1200W at 1 ohm, 1 x 600W at 2 ohms, and 1 x 300W at 4 ohms. A mass-loaded extruded aluminum heat sink handles thermal management with no cooling fan, so there is no fan noise and no intake to clog with dust on a trail machine. An air core transformer supports the high switching frequencies the Class-D output stage runs at.

Tuning covers a variable high-pass from 15Hz to 1kHz, a variable low-pass from 50Hz to 10kHz, and built-in bass control with 0 to 12dB of boost, with input sensitivity from 0.2V to 5V. Frequency response runs 10Hz to 11kHz with under 0.1% THD. Preamp outputs let a second amplifier join the system later without splitting the source signal.

Over and under voltage, short circuit, and thermal protection circuits cover the amplifier and the subwoofer, and delayed turn-on keeps hisses and pops out of the speakers at startup. Connections take 0 AWG power and ground and 12 AWG speaker wire through molded angled terminals behind a 100A external fuse. The included bass remote adjusts level from the seat and shows green when powered, red in protect. Weight is 5.15 lb.
