Brand: Hifonics
SKU: 6584047
Rating: 5 (2 reviews)

Key Specs
- Maximum Watts x Channel @ Ohms: 3000 x 1 @ 1 Ohm, 1500 x 1 @ 2 Ohms, 750 x 1 @ 4 Ohms (This is the maximum load the speaker, subwoofer or amp can drive.)
- Amplifier Class: D (An amplifier's mode of operation, specifically the conditions in which its electrical current flows for the duration of an audio signal, determines its class. Each class has its strengths and weaknesses when it comes to power efficiency, levels of crossover distortion, and overall sound quality.)
- Number Of Channels: 1.0
- Bass Boost: Variable (Circuitry that boosts the bass response of the amplifier, improving audio reproduction enhancing the sound of low frequencies. Fixed boost means the level of bass response is preset, whereas variable boost allows the user to make adjustments.)
- Low-Pass Crossover: Variable (Devices with this function allow only audio frequencies below a chosen cut-off frequency to pass through to a speaker or sound system. A device may have a cut-off frequency predetermined by its manufacturer (fixed), multiple cut-off frequency options to choose from (selectable), or have the capability for the frequency to be configured by the user (variable).)
- High-Pass Crossover: Variable (Devices with this function allow only audio frequencies above a chosen cut-off frequency to pass through to a speaker or sound system. A device may have a cut-off frequency predetermined by its manufacturer (fixed), multiple cut-off frequency options to choose from (selectable), or have the capability for the frequency to be configured by the user (variable).)
- Speaker-Level Inputs: false (Also referred to as high-level inputs. Enables the amplifier to receive a sound signal from another device that does not have RCA, or low-level, inputs.)

Audio
- Number Of Channels: 1.0
- Minimum Frequency Response: 10.0 hertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The minimum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
- Maximum Frequency Response: 10.0 kilohertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The maximum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
- Total Harmonic Distortion: 0.1 percent (Measurement of the harmonic sound distortion. The lower the percentage, the cleaner the sound.)
- Signal-to-Noise Ratio (SNR): 88.0 decibels (The ratio of the desired signal's strength to the level of background noise. A ratio higher than 1:1, which equates to greater than 0 decibels, indicates more signal than noise.)
- Bass Boost: Variable (Circuitry that boosts the bass response of the amplifier, improving audio reproduction enhancing the sound of low frequencies. Fixed boost means the level of bass response is preset, whereas variable boost allows the user to make adjustments.)

This Hifonics COLOSSUS PRO mono block amplifier delivers 3000W 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: Mono only.
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.
