The Hifonics HCM-800.4D is a compact four-channel Class D car amplifier rated at 800 watts max. It puts out 4 x 100 watts at 4 ohms, 4 x 200 watts at 2 ohms, and 2 x 400 watts bridged, in a chassis about 10.5 by 5.3 by 2.7 inches and 4.4 lbs. Its small footprint suits motorcycles, UTVs and tight car installs where a full-size amp will not fit. Against larger four-channel amps it trades some headroom and clean-power margin for size, but it keeps useful tuning: variable high- and low-pass crossovers, a bass control, speaker-level inputs and a 0.2-5V input range.

The Hifonics HCM-800.4D is a Colossus Mini four-channel amplifier that delivers 800 watts in a small, ultra-compact body. Its size suits motorcycles, UTVs and cars. It uses a full-range Class-D chipset, which works with a wide range of drivers, including pro-style speakers.
It runs in stereo or mono bridged mode. Controls include a variable electronic 12 dB per octave crossover and built-in bass control. Its LED shows green when the amp is on and red when it is in protect mode.
The amp has a mass-loaded extruded aluminum heat sink and needs no cooling fan. Over/under voltage, short circuit and thermal protection circuits guard the amp and the vehicle. A delayed turn-on function helps prevent hisses and pops when the amp turns on or off. Inputs are nickel-plated RCA jacks, and the power, ground and speaker connections use an angled, molded terminal.
