Hifonics 35th Year Anniversary Amplifier: Product Overview



Hifonics Transformers

Efficient Circuitry:

The efficient and audiophile grade electrical components are secured to double-sided military grade glass resin epoxy circuit boards. This along with the stronger copper traces creates efficient circuitry for high voltage to pass through with no noticeable distortion.




Twin Turbo power supply

Twin Turbo Power Supply:

The Hercules 35 uses a Pulse Width Modulated MOSFET power supply design. The twin turbo coil PS maximizes the voltage from you car to the output MOSFET devices by keeping the voltage contanst through the Ultra-Fi output devices.




Ultra-Fi MOSFET outputs

Ultra-Fi MOSFET Outputs:

The Ultra-Fi MOSFET outputs produce high power with minimal distortion. They are typically used for music production where high power, efficient cooling and minimal distortion are key. The Hercules 35 Series is designed with everything needed to play your music the way it should be heard.

Nice amp!

I have this amp running a set of 6 1/2 components, and a set of 6 1/2 coaxials.
Nice clean power, does get warm but I have had no issues with it cutting off. Love the matt blue finish!

By Cadillac Karl on April 27, 2016


great amp

I bought this amp because i already have a hifonics hfi2000 for my American Bass subs. I am very pleased with this amp. I live in Arizona and I need something that won't overheat and shut down when it gets hot. Great value. Would recommend highly.

By George on March 28, 2016 Checkmark Icon Verified purchase


Beautiful

Received this amp today, opened it up and looks very well built. Its a dark blue and matches my project car perfectly. I can't wait to run it and try it out. I bought both mono and 4 channel 35th anniversary edition. Would buy again. This is my first hifonic purchase and so far I am not disappointed .
