COLOSSUS PRO Monoblock 1500 Watts Max Super D-Class Amplifier

Hifonics COLOSSUS PRO monoblock amplifier delivers 1500 watts in a more efficient half-bridge design with fewer components resulting in higher power output.

Key Features:

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.
