This Hifonics COLOSSUS PRO four-channel amplifier delivers 2000W in a more efficient half-bridge design with fewer components, resulting in a higher power output.

• Ultrahigh efficiency: A thoughtful power supply coupled with carefully selected parts results in one of the most efficient amplifiers in Hifonics history.
• Half-bridge construction: A more efficient design with fewer components provides a higher power output.
• Ultralow EMI: Ensures minimal interference with other electronic systems of the vehicle.
• 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: Four-channel operation mode allows either stereo or mono bridged operation.
• Clean board construction: Multilayered printed circuit boards (PCB) with surface-mount components require fewer parts and result in a cleaner design.
• Full-range Class D amp: Features a full-range Class D chipset, making it compatible with a wide range of drivers, especially pro-style speakers.
• Thermal management system: Variable speed fan cooling combined with the mass-loaded extruded aluminum heat sink results in better thermal management and output performance.
• Power supply: Iron core transformer assists in an ultralow EMI design while providing high power at an unmatched value.
• Delayed turn-on function: Ensures compatibility with a wide range of source units to eliminate any unwanted turn-on/off noises, such as hisses and pops.
• Connection type: Provides a 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: The Hifonics logo is illuminated with blue LEDs, and the COLOSSUS logo badge is made of fly-cut CNC machined aluminum for a sleek and stylish look.
• Triple protection circuits: Over-/under-voltage, short circuit, and thermal protection circuits give you peace of mind that your investment (audio system and vehicle) will be protected under nearly every circumstance.
• Bass remote included: The included bass remote allows you to adjust 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 protection mode.
