  • Great amplifier for the money!
Model: BG-4000.1D
The media could not be loaded. So far this amplifier is pretty impressive. Makes tons of power and looks great. You will definitely need to upgrade your electrical a bit to safely run this amplifier an extra battery to support up to 3000 watts RMS.

  • Does NOT last long
Model: 3300 Watt Monoblock
i had bought this one after buying a previous weaker model for my subs thinking i maybe blew my amp out thinking my subs were to strong....after about a 3 weeks using this amp i had the SAME issue...the amp slowly stopped working, i took it to not one not two not three but FOUR sound shops and they ALL said the SAME thing...."these amps are no longer good and they break quickly only their older models are worth anything". i loved how they both worked at first but like i said after about 3 weeks in they started having major issues...this one just completely died on me and stopped powering my subs...im using two KICKER CVX 122's really annoying issue. i bought a kicker amp that was just as strong and my subs kick harder work better and its been well over 4 months and i have no issues at all! this is def not a brand i would req to any sound enthusiast anymore sadly ... show more

  • Worth the money major upgrade
Model: 1000 Watt 4 Channel
So it began with a high phonics Zeus model which sounded great I had for JL audio speakers, C series, components in the front coaxial in the back. Everything sounded good amplifier ran nice and cool no issues. Read about the Brutus series saw that I had a couple extra features I liked it had better power transfer to sound. It has less distortion and uses power more efficiently. I installed on the same footprint it was the same footprint as the Zeus but what a difference. The base output was stronger the highs were clearer overall song quality was totally noticeable. I’ve been doing car audio for 25 years and I was very impressed with these amplifiers. But if I was starting from scratch I probably would’ve just bought the Brutus to begin with. I also just ordered a 1900 Brutus mono amp that’s on the way that is going to be an upgrade from the Zeus 3300 will see how it sounds ... show more

  • Does The Job
Model: 1000 Watt 4 Channel
I bought this amp about a year and a half ago. I have 2 kicker 6.5s, 2 kicker 6x9, and two Skar 6.5 subs wired to it. When i first got it, it would run for a few minutes and then go into protect mode. Rewired the speakers and now works great, so i believe the issue was not the amps fault. It does, however, have a hum to it even after adding ground loop isolators. Havent figured that one out yet, but when the music is up you cant hear it. ... show more
