Features & Benefits

Ultra-High Efficient Design A thoughtful power supply design coupled with carefully selected parts results in the most efficient amplifiers in Hifonics history making them truly POWER FROM THE GODS.
Half Bridge Design A more efficient design with fewer components results in higher power output.
Ultra-Low EMI Design Minimal interface with other vehicle electronic systems.
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 Mono only
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 PRO amplifiers feature a full range Class-D chipset making them 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 the ultra-low 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 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 mangement profile.
Stylized Badging The Hifonics logo is illuminated with blue LEDs and the Colossus logo badge is fly cut CNC machined aluminum (which gives a sleek and stylish finish).
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 protect.
