Features & Benefits

Compact Design Small footprint design suites 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 mangement profile.
Stylized Badging Fly-Cut CNC Badging- The Hifonics and Colossus logo badges are CNC machined aluminum (giving 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.
