Mt. Olympus

This is the top of the mountain. When your system design demands the absolute best, you will not suffer the excuses of mortals – Mt. Olympus from Hifonics has been engineered over two decades for a perfect balance in sound quality and power.

Ultra D-Class™ technology is at the very nerve center of our flagship Mt. Olympus. The proprietary “Ultra-D” design uses high-speed microprocessors with proprietary D/A conversion algorithms to efficiently control the Mt. Olympus current consumption. At very high listening levels. Hifonics Ultra D-Class results in lower distortion, higher current efficiencies and less heat than conventional D-Class amplifier designs. Compared to the competition, Ultra D-Class amplifiers are easier on your car’s charging system.
Super A/B Class™ - Big power alone does not make a great system design; This is why Hifonics developed Super A/B Class™ as a perfect sound quality design for the stereo amplifiers to match the Mt. Olympus models that utilize the Ultra D-Class™ circuitry. Super A/B Class™ designs are based on top 1% tolerance grade components. Super A/B Class insures the Mt. Olympus stereo amplifiers fill your needs for high-power and ultra-high end sound.

The perfect system design, Mt. Olympus with Ultra D-Class™ on the subwoofer system and Super A/B Class™ for the mids and tweets.

2000W RMS 1-Channel Monoblock Mt. Olympus Series Class D Amplifier.


The Mt. Olympus amplifiers are all CTA-2006B compliant. CTA stands for Consumer Technology Association and Hifonics has been a member for decades. In 2016 the program previously known as CEA Certification changed to CTA-2006B to reflect the changes to the organization and their initiatives.

Specifically for the Hifonics Mt. Olympus amplifiers, the Primary Output Power should, according to CTA2006, be measured with 14.4V DC supply, a 4-ohm load and with 1% or less total harmonic distortion in the output.
