Hifonics HCM-400.4D COLOSSUS MINI Ultra-Compact 400 Watt Four Channel Amplifier

The Hifonics HCM-400.4D COLOSSUS MINI is an ultra-compact four-channel amplifier engineered to deliver 400 watts of high-efficiency audio power in a space-saving profile. Built with full-range Class-D topology and Ultra-Fi MOSFET output devices, it powers a versatile array of audio systems across automotive, motorcycle, and UTV setups.

Featuring a mass-loaded extruded aluminum heat sink, this amplifier ensures effective passive thermal management without the need for cooling fans. Its high-end preamplifier circuitry and corrosion-resistant nickel-plated RCA jacks accept a broad range of input signals for clear sound reproduction.

Multi-layer printed circuit board construction and triple protection circuits against over/under voltage, short circuits, and overheating deliver dependable performance. Angled molded connection terminals ensure streamlined wire management and reliable signal transmission.

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.
