Hifonics HCM-800.4D COLOSSUS MINI Ultra-Compact 800W 4-Channel Amplifier

The Hifonics HCM-800.4D COLOSSUS MINI ultra-compact four-channel amplifier delivers 800 watts of high-efficiency output in a small-footprint chassis. Built with a mass-loaded extruded aluminum heat sink and Ultra-Fi MOSFET power supply, it maintains optimal thermal dissipation without requiring cooling fans.

Designed for versatile installations across cars, UTVs, and motorcycles, this full-range Class-D amplifier supports both stereo operation and mono bridged configurations. It features nickel-plated RCA inputs, multi-layer circuit boards, and secure angled terminals for reliable signal delivery and clean wire management.

Integrated triple-protection circuitry guards against over-voltage, under-voltage, short circuits, and overheating to ensure continuous system reliability. The included wired bass remote allows quick output level adjustments from the driver's seat.

Key Features

Highlights

• Compact Design: Small footprint design suits a wide range of applications like motorcycles, UTVs, and automotive vehicles.
• Mass-Loaded Heat Sink: The mass-loaded extruded aluminum heat sink results in better thermal management and output performance – no fan cooling required.
• High-End Preamplifier Circuit: Accepts a wider range of input signals.
• RCA Inputs: Nickel-plated RCA jacks create an efficient connection that is corrosion-resistant.
• High Tolerance Output Device: Ultra-Fi MOSFETS are designed for high output power and thermal dissipation through a proprietary coupling method.
• Operation Mode: 4 channel operation mode allows either stereo or mono bridged operation.
• Clean Board Construction: Multi-layer printed circuit boards (PCB) with surface mount components require fewer parts and result in a cleaner design.
• Class / Topology: Full Range Class-D - All Colossus Mini amplifiers feature a full range Class-D chipset, including the mono models, making them compatible with a wide range of drivers, especially pro-style speakers.
• Power Supply: Air core transformer is more effective for higher frequencies and energy loss due to its open-core design.
• Delayed Turn-On Function: Ensures compatibility with a wide range of source units to eliminate any unwanted turn-on/off noises like hisses and pops.
• Connection Type: Secure molded connection terminal for all Power, Ground and Speaker connections. Angled for ease of access while creating a clean wire management profile.
• Stylized Badging: Fly-Cut CNC Badging- The Hifonics and Colossus logo badges are CNC machined aluminum.
• Triple Protection Circuits: Over/under voltage, short circuit, and thermal protection circuits protect the audio system and vehicle under nearly every circumstance.
• Bass Remote Included: The included bass remote allows adjustment of the bass level relative to the setting on the amplifier end panel. The LED indicator light displays green when the amplifier is powered on and red if the amplifier enters protect.

Compatibility

Universal design compatible with 12V mobile audio systems across cars, trucks, UTVs, and motorcycles requiring 4-channel or bridged mono amplification.
