Sundown audio x-12 on 2 hifonics goliath 4k.
Incredible amp! Called maxxsonics rated at 2800 rms. In my experience it may be just slightly under that but it's between 22-2800 rms Running 2 of these at 2.3 ohms on 2 sundown audio x-12's If you want to see more great details you can go check out my video on you tube reviewing this, it comes with a bass knob and a great aesthetic. Very impressive on not getting hot.

It's about 2000 rms give or take at 14 volts with good clean power running it
It's an ok amp. Wish it would present the rms somewhere online or perhaps the box or manual maybe .. not kool. And definitely not 4000 watts in which I didn't expect from hifonics but even the lower end amps show the rms and the false max lol .. anyway still a decent amp for 2...1000 watt rms subwoofers and no more than that. Very efficient at that point
