This line of Mmats amps is a huge success in my eyes, as it has always been. I own 2 of the HD4000.1’s and I can’t begin to explain the capabilities of these amps! With voltage dropping to 12.2v and rise jumping to 2.1 ohms, I was clamping 3800w out of each of them. When you look at the power rating given at 2 ohm, this is above and beyond what I expected out of them. Well worth the money!

Hands down best amps I have ever owned. Small footprint design and creates unbelievable power. I would never buy anything else period.
