Brutus Series Amplifiers

When it is time for some serious power for your car audio system, Hifonics is the way to go. The Brutus Series Amplifiers are in line with the high power output that Hifonics is known for.

Incorporating Super D-Class circuitry allows for dedicated, efficient power for higher bass response without sacrificing sound pressure. The Ultra-Fi MOSFET outputs chosen for the Brutus Series are typically used for music production where high power, efficient cooling and minimal distortion are key. They allow these amps to produce high power with minimal distortion.

The included bass knob can allow you to adjust your bass to match any genre of music you listen to. The Brutus Series also has RCA outputs for daisy chaining multiple amps together for even more power. Designed to get loud, the Brutus Series Amplifiers are ideal for a pounding audio system!

As good as you can get for the price!

I have this amp powering two sets of MB Quart QS216 and I sometimes just ride with my subs off just from how good thus amp pushes them. But it does get hot. I have a kinetic 3800 battery and a Rockford Fosgate 10 farad hybrid capacitor powering it and it's still power hungry! Make sure your power is up to par!

BRX616.4

Like all of Hifonics Brutus models this amp is equip with the lovely illuminated "HIFONICS" lettering across it. The amp puts out plenty of power for my alpine type r 60c speakers. I am once again more than satisfied by Hifonics.

Hifonics 4 Channel

This amp is great for the price.Pushing 4-6x9, and 4-6.5. Doesn't over heat or lose power. Especially for what I have hooked up to it. Great amp!

Great Additional Power

Have never set up a 4 channel amplifier before but was fairly easy with the help of the internet! This amp was a great price and definitely necessary to get the peak performance out of my aftermarket speakers. My built in amplifier for my double din wasn’t even pushing my speakers a quarter of the way they could be pushed. Fast delivery and great feedback. 10/10 would recommend!

Brutus Rocks

Great Amp, no problems installing the unit. I made a rail mount, bolted through the floor and then mounted the Amp over the bolts.

great product for price

Bought this great product for my door speakers. And work great used for over a year and still, going great not one issue..

No cons at all..

Not bad for the price

The is not a bad amp for the price and I've always like the illumination of the hifonics Amps. The only concern I really have for this amp is that once I hooked everything up correctly, I have been having really bad noise interference the increases and decreases with the engine rpm. I wish I would have spent alil extra money and went with the Rockford fosgate 70 or 75x4 amp. Also, the modes like the full, hi, low, and hi/low don't really work all that well. Again, I really wish I would have gone with the Rockford fosgate amp.
