The Legend Redefined

There’s more to this multi-channel amplifier than meets the eye. Hifonics Zeus amplifiers are redesigned to not only look different, but also provide clean, true power. Designed to complement the Brutus Class D series of amplifiers, there’s no better match for a multi-channel amplifier. The newly implanted vertical fin heat-sinks are designed to allow maximum heat dissipation from the amplifier, which allows this amplifier to run much more efficiently and have less impact on your car battery. Their new series of amplifier is now CEA-2006 compliant, meaning their specifications have met CEA standards and their output is certified and true.

Zeus Amplifiers incorporate Ultra-Fi MOSFET output devices, which will decrease overall distortion and allow your amplifier to output nothing but pure high-fidelity audio. The smoothness of Ultra-Fi will remove electrical interference and noise that’s usually generated by amplifiers, and allow the user to enjoy noise-free music. Zeus amplifiers combined clean power, heat dissipation and Ultra-Fi circuitry makes this amplifier unrivaled for any application. The God’s have bestowed clean, pure power. Enough compromising – it’s time for a Zeus.

best buy

Didn't think there was much diffrence in amp's owned Sony's for years. Bought this amp. Wow i was an idiot. What a sweet sound, balanced and clean. if i had to pick a con, it would be give lots o room for mounting. its a bit big.... but what a sound. good value here!

Gets the job done

For a lower cost 4 channel amp this thing puts out the power needed for 2 good sets of full range speakers... This thing makes your system match the bass output and stops the muffled over powering bass from subs.... now I just wish HiFonics mono amps were able to output what they are rated at... even though they are CEA2006. Pffft

Awesome Amp

The title says it all, this is an awesome amp. I have been into car audio for about 20 years and have had many different amps and these are high quality. It replaced a Rockford Fosgate P450.4, it has a warmer, cleaner sound and adds a nice punch to my components. My DVD's sound amazing. I have ordered a Hifonics Brutus BRZ1700.1D for my HX2 12's.

Great Amp

The ZXI and BRZ line of amps are incredible and my BRZ1700.1D has never failed me once. Trust me this is a great buy.

great price with true power

This amp reproduces great sound for your highs, it stays cool, and has a cool look. You won't be sorry with this amp for mids and highs.

Impressed

I've got this amp running Infinity Kappa 6x9s and two JBL 10s. 2 ohms per channel. It pushes the subs well. It has very clear sound on the Kappas. No distortion, no noise, and can play far louder than i can stand. High quality for a very reasonable price. The amp is big and well built. Made in the USA. Unless you want to spend a lot more on an amp, buy this one. I will be buying more Hifonics amps in the future.

Great Amp, Clean Power

I've had this amp in my truck for a little over 7 months now and absolutely love it. I'm pushing a pair of Rockford T1 5 1/4" components and T1 6.5" components as well. This amp powers the speakers amazingly. The only complaint I have with this amp is it gets warm from time to time, however after throwing a fan on it I haven't had any problems. Great product for a great price.

Won't be dissapointed, great amp!

Had this amp over 6 months now no problems at all. Have every feature you need on an amp. True rms ratings unlike older Hifonics equipment. Don't hesitate to buy.

Great amp for the price.

Beautifully made amp. Powers my Alpine SPS-610c components wonderfully. Hifonics always provides very good quality products for the price. Wouldn't buy anything else.
