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.

Garbage!!!

The following review is for a previous version (10-COLOSSUS).

Would not recommend to anyone! Amp lasted less than a week and it burnt up! Voltage never below 13.5, no clipped signal all connections were nice and solid cheap quality amp all around! Plastic end caps on amp to mount the 20+ pound amp didn't seem solid! The bottom metal plate is flimsy and buckles when you hold the amp. I wonder how poor the quality is on their other lines are if this is supposed to be top of the line!! I'll never purchase a Hifonics product again.

The following review is for a previous version (10-COLOSSUS).

colossus

The following review is for a previous version (10-COLOSSUS).

I like it, it has alot of power right now. I have 2 15" cvx kickers (2000 watts each) bridged that the amp is pushing. Next ima get 2 more 15" cvx and make my sound system even more loud, if you want good quality i prefer this amp (3200 watts).

Its a Beast

The following review is for a previous version (10-COLOSSUS).

The Hifonics Colossus actually has a little history behind it, but in a nutshell, its an amazing amplifier that I wish I never got rid of. Its so powerful that a while back, it was banned from a competition for them thinking it had 2 amplifiers in 1 shell. Though this was the case, it lets you know how powerful it is, rather than me just describing how awesome it is.

good amp, but mine died

The following review is for a previous version (10-COLOSSUS).

i had this amp for about a year on 3 sa8 v2s, it got loud but was never pushing its full capacity because it sucked so much current that i could never keep it fully supplied. i had a stock alternator with the big 3, and a large deep cycle battery and couldnt turn it up past half way. then one day it died and sonic gave me a bunch of store credit

i'm the guy with the vic. i took out the hcca 10's and put in another colossus i have 3 batteries powering them, at idle im at 15.1 to 15.3 volts before play. i put 2 PSI platform 3 18's in the trunk tuned at 30 hrtz pushing 3200 rms to each one. i float empty monster cans in the window. gravel bounces off the ground. first comp is in a couple wks, ill let ya know how loud i am.

Raw power here!!!

The following review is for a previous version (10-COLOSSUS).

I'm running this amp with 1 12" cerwin vega stroker pro. Hits so hard pops my ears, leaves me delirious. Makes you sick. HOWEVER, you must have the big three, extra batteries, hi output alternator. Once that's done, Big pay off.

Hifonics all the way

The following review is for a previous version (10-COLOSSUS).

Wow This amp is a BEAST its powering 2 12" Fi BTL. Let me tell you dont let this amp go. It's a flagship from Hifonics. It beats every other brand in its class.

perfect match

The following review is for a previous version (10-COLOSSUS).

Have 2 hcca 10.2 in the back of a crown vic. This amp gives them 1600 rms @ 1ohm each. The windsheild wipers bounce off the glass. The back seat shakes like its going to explode. I'm thinking next time 2 of thease amps with 2 hcca 15.2 @ 2ohms bridged 3200 rms each! That will be very interesting to hear.
