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.

Bought this 4 channel amp about 5 months ago and it was liek night and day difference from deck to amp, amazing power outputs in the 3 ch mode i hit 137.6 dbs on one 12 and 80 rms! at 4 ohms thats good. even in 4 ch mode the sound is clear crisp and sharp, right on que very pleased with amp if your looking for just a little boost in your speaker output this is plenty of powa yo. hit it up! Cheap as no other for the power output.

Lot of Power in this little guy
I purchased this as a package deal with the Hifonics Zeus ZXi65.C Component Door Speakers with Tweeters and Crossovers. This amp is amazing for its size. The door speakers peak out at 500 watts so I have 2,000 watts worth of door speakers and I believe this amp is 320 RMS Bridged so it is a little underpowered, but still does not get as hot as one would think. The new heat sink fins really help. If it does get too hot it shuts off automatically like it did when I tested out a sub I have. For the money, you cant beat it. Although I will be upgrading to a larger amp once I get my subs and their amp to match so my mids/highs aren't drowned out by me subs, I still recommend this amp.

Solid and beautiful design
Upon receiving this amp (super fast and free shipping) I was impressed by the heft. I've never bought Hifonic before, but was recommended by a friend who loves their amps, and I can see why. Instructions were easy and it was a nice surprise to see the logo light up in a cool blue when the amp turns on. I have 4 sets of Polk Audio 6.5 speakers running and the Hifonics has no problem delivering juice to these. It runs cool after 2 hrs. and has enough levels for you to tweak the sound to your preference.
I'm planning on upgrading to Jl audio component speakers for the front to take advantage of the power in this amp and will update this review in a few months, but so far I'm very impressed with Hifonics!

I have installed this as my primary 4 channel amp to drive both my 6x9 and 6" fronts. The amp produces a very clean signal and I am pleased with the output, definitely worth the money.
