The 35th Anniversary of Power From The Gods and Hifonics are celebrated with throwback competition amplifiers. CTA certified RMS amplifiers designed around three models engineered to create the perfect system design. A Large Ultra D-Class™ Dual Mono, a standard Super D-Class™ mono and a four channel Super A/B Class™.

The entire line up is designed with an old school heatsink that harkens back to the beginning of the car audio revolution, but now Hifonics boss has twisted and squeezed the engineers to deliver new technology and features that make these SUPER AMPS the best money and man can design.

Here is the break down of the Super Amps – which include the Colossus, Goliath & Helios super amp models.


Colossus 35th Anniversary

The Colossus celebrates the 35th Anniversary of Hifonics with a CTA certified super amp. The Colossus uses the Hifonics engineer’s technology, Ultra D Class™ in a Dual Monoblock subwoofer amplifier that will deliver 3400 watts RMS.

Inside the SUPER AMP Colossus Dual Mono Ultra –D-Class™

The Colossus represents Hifonics best signal processing and control features designed for a big mono amplifier. Key among them is the Dual Mono Ultra D-Class™ topology which helps the Colossus develop huge power while minimizing voltage strain. The “Dual” means there are literally two amplifiers in one heat sink for system designs that need to develop large power without giving up additional space.

The Colossus, Goliath and Helios use powerful and efficient transformers and audiophile grade capacitors and resistors. Electrical components are both through-hole and surface mount pieces that are all secured to double sided military grade glass resin epoxy circuit boards with beefed up copper traces. This ensures high voltage can pass through the circuit with minimal distortion in the signal path.

Twin turbo power supply toroids in a Pulse Width Modulated MOSFET power supply design assure that car voltage is maximized from battery through to output MOSFET devices.

All the Hifonics 35th Anniversary SUPER AMPLIFIERS utilize Rock solid Ultra-Fi™ MOSFET outputs which are selected by the Hifonics engineers to be balanced for power output. This keeps power smooth even during demanding peak in the music.

In the signal path, Colossus uses the unique ParaQ™ circuit allowing full parametric control of the bass equalizer which can be controlled by the diagnostic bass remote.

Controls allow from a center frequency of 30hz up to 100hz with a 0 to 10 dB boost with the width of the frequency to be adjusted from very narrow. As an example you might focus on 32hz only – or a wide adjustment, where with 40 as the “center” frequency, adjustments are made from 35 to 45hz. ParaQ™ delivers the most control of bass frequencies than any amplifier ever designed by Hifonics engineers. Read the white paper from Hifonics engineers about ParaQ™ (coming soon!).

Large Power / Large Ground

The Colossus is a Dual Mono Ultra D-Class™ amplifier. This means getting amperage from your electrical system and a solid ground are critical. Hifonics engineers assure that Colossus can accommodate 1 O/T for power and ground. This feature allows more current to get into the amplifier with the ability to establish an equal ground.

Rounding out the features are a variable subsonic and low pass electronic filters as well as Phase Shift and adjustable voltage from 9 Volts to 0.2 Volts.

The Super Amps line of car amplifiers also includes the Goliath Super D Class Mono car amplifier and the Helios Super A/B class 4 channel car amplifier. Both of these amps feature an additional output set of RCA jacks to eliminate the need for splitter cables. The Goliath pushes out an impressive 3000 watts RMS and the Helios puts out 150 watts per channel for a total of 600 watts RMS.
