Absolutely amazing amplifier, I’m using it for running 4 6x9 and 2 tweeters. It does run a little warm but overall is an amazing amp I’ve ran it pretty hard and it hasn’t gone into protection mode once so it’s pretty durable I would say. It is very tuner friendly for everything.

Honestly it overheats sometimes, but I've had it for a while before I went more professional with Sundown & Deaf Bounce. I must say though I pushed this thing, had it running speakers and a subwoofer damn near maxing it out every time I drive, and it still works like a champ!

This is a piece of junk. Won't turn off until u remove the power cord. I'm immediately requested a refund and this company keeps saying they sent me a prepaid label but never did! Amazon refused to help too. I paid almost 200$ for this. Amazon keeps telling me it's a 3rd party company even tho I ordered from Amazon! I guess I'm stuck with a piece of junk!🤬🤬

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.

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.

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
