Hifonics BG-1900.1D Brutus Gamma Monoblock Super D Class 1900 Watt Car Audio Sound System Subwoofer Speaker Amp Amplifier with Bass Knob

Not really sure if it's 1900 watts at 1ohm load on my two12" subs. But definitely rattling windows and mirrors.

Very good.Clear sound strong bass don't need to upgrade no more.I will have to change my whole wiring system.But I am good.Thank you love the blue lights

Wanted a hifonics amp for awhile after watching a video on youtube with someone using a 1606D brutus. Heard stories and all this other stuff about hifonics in recent years, so I was hoping I wouldn't be let down. I don't know how the amps are now compared to the old ones, but this one makes me happy. My current setup is nothing fancy, stock stereo for now, kicker KISLOC2, and 2-12" pyramid subs in pyramid bandpass box. I haven't figured a way to wire in my amp fully yet but I have 4 gauge knukonceptz wire to use. I used a 6 gauge jumper cable with one side cut off to test the amp with. So far I'm running it mostly untouched, only thing changed was gain. For my setup it might be overkill, but I'm happy with it for sure. It did come with a hole in the box, nothing missing or damaged however. *Update* 12/28/23 It's a beast. The pyramid speakers didn't last at all, expected as they were cheap. Got 2 skar 12s rated 1600w. They flex like crazy, my car drops in rpm at lights if volumes left up. Again, happy with this purchase.

Using this to push two 10-in Kickers each rated at 350 watts. This amp provides more than enough muscle to do the job with my set without even warming up. The power I'm getting coupled with how many options exist to tune the output floats my boat really well. The amp is well-made, feels very sturdy, was easy to install, looks great, and isn't so overly large. Do your research though. This amp, for what I am doing, is probably overkill. There are a number of YouTubers who have reviewed/tested this line of amps, and for me the performance I'm getting so far validates what I've seen out there over the past year or two. Pleased so far.

Es bueno, 100% recomendado

Best bang for the buck, reminds me of the Gladiator series from 2015 in power. I have double 0 Guage inputs, big 3 and the small kinetic battery on 1 12" Audiopipe TXX-BE Dual 4(remember these?) 6th order wired @2 ohms, makes giggle like a school girl at 27 hz. Next sub will be the new BDC4 on this amp at 1 ohm. Got mine for $158 in November of 2020, get these while their cheap!!!! Update, still hammers my truck, will definitely push more. Very bright Leds coming out from underneath my back seat!

The amps are defective. I bought one and the gain dial was defective. The replacement was defective in the same way. They charged me twice for two defective amps. Do not buy from Spreetail.

The cable connections are so much better than most other amps at this price point. These things are rugged, I have this thing screwed into my sub box which just flops around in my trunk most of the time. I have it hooked up to a single 12” Sony xplod in a sealed 1.3cu/ft box and it BUMPS. Not to mention the hiphonics logo looks awesome when it’s lit up, AND IT COMES WITH STICKERS!!!

Do not buy amp stopped working after a week of use gains were set clean not even turned all the way up

Muy buen producto vieja escuela

Tarde en instalar, porque mi proyecto estaba en taller de pintura y cuando lo use al mes me di cuenta que después de 1 hora de uso deja de mandar audio, y a volumen minimo. ( nunca se exigio hasta frio trabaja, pero despues de ese tiempo aprox deja de mandar audio).

Un manual bien especificado como que función tiene cada perilla y un rango aproximado de ajuste para un buen funcionamiento

Muy buen amplificador, lo compré para un subwoofer cuadrado Kicker y suena muy bien. Lo único que no me agrado fué que el control de bajos me llegó con unos rasguños, un poco decepcionante. Por eso las tres estrellas. Todo lo demás muy bien.
