Brutus BRX Amps: Brutal to Competition

Hifonics Brutus Crossovers

Accu-Cross Crossovers for Sound Shaping

The Gods have struck again from Mt. Olympus. The famous Brutus amplifier has gone through a redesign and now features a new look along with amazing sound. The design for the new Brutus BRX amplifiers has a blue illuminated underglow that gives the amplifier a floating appearance when properly mounted.

The molded and angled illuminated terminals add to the stylish design and also provide stress-free installation access. Accu-Cross crossovers allow for adjustments and sound shaping. The Ultra-Fi MOSFET power supplies ensure the amplifier can maximize its sound capabilities. The new Brutus BRX amplifiers take it to the next level, and are certainly a brutal amplifier.



Hifonics Brutus Terminals

Molded and Angled Illuminated Terminals

The full-range multi-channel Brutus BRX amplifiers all feature Super A/B Class technology. This complex circuitry was initially developed purely for the flagship Mt. Olympus amplifiers – however this superior technology was passed on to the Brutus line as well. This efficient circuitry allows for maximum sound quality while also ensuring maximum efficiency.

Initially Brutus amplifiers were only monoblock amplifiers by Hifonics, however for 2013 they deicded this amplifier series was too good to pass up, and added two-channel and four-channel alternatives to their purely subwoofer filled lineup. These new stylish multi-channel amplifiers were welcomed with open arms by the car audio industry, and have performed extremely well on the market since being released.

Great beginner amp

I say beginner amp because of the price.This thing will make your system jam. It's really loud and sounds good from what I can tell. It's really hard to say how it compares to other amps unless you swap amps in the same car with the same system. If I could hear my same system with a $400 amp to hear the difference that would help determine how this amp compares, but I can't do that. But overall, this is a good amp with a great price. And from my experience, Hifonics makes a quality product. I am running this amp to Infinity 6.5" rear door speakers and Infinity 6.5" components up front. I also have a Brutus 1200.1 for my subs for 2 years and it works flawlessly.

Hifonics Amps Are GREAT!

Got this to power front door component speakers and 3-way rear deck speakers (both JBL). This amp is fantastic and freaking awesome! It sometimes gets a little warm when I am blasting music, but usually it stays pretty cool. And speaking of cool, the blue lights on it are FREAKING COOL!!! It has all the control I want with an HPF, LPF, and BandPass, the number of different ways to use this amp are infinite! I love this amp, I have had no problems with it and I would be shocked if I ever do.

Great Amplifier

It turns any aftermarket speakers into Crystal clear sounding speakers and you get that extra bump in bass out of them. No doubt anyone who's not looking for something crazy loud for an audio system this amp does the trick. Lastly I got this hooked up to Rockford Fosgate prime 4" & 6 1/2" speakers and wow. The only problem I have is I was looking for 50w rms per channel but oh well. However now they come out with one that offers 50w rms but no doubt the looks of this amp are way better in comparison so the 10 less rms watts I can live without.

Great Amp!!

I bought this amp to run all of my pioneer speakers for the inside of my car and it really does the job. It pushes my speakers just right so that they are all extra loud and its at a great price you cant pass up on this amp.

Great Amp

I really can't say how this amp compares to every other amp since this is the only amp I have had in my car. But it makes my stereo jam. I have it running to Infinity components up front and 6.5" Infinity speakers in the rear doors. I then have a Hifonics Brutus 1200.1 powering 2x10" Alpine Type R's. All I can say is my stereo system kills. It's so loud I can't turn it up all the way. And for the price, you can't beat this amp.
