Affordable Bass
This is a good amplifier to me, I had a Kenwood xr1000.1 that died on me so I went full sundown for my SQL build and this one takes the cake for the ability to run 1250w and 1 and 2 ohms. Great quality and doesn't get too hot for powering a sa classic 12'

Powerful!
It could have a few more features but, it pushes my two Fosgate P3 12's hard! Worth the money and this review is after 6 months of being installed. No problems at all.

Fried on me!
It fried on me after like 100 hours of use, I had it paired with the sundown 8 inch subs (2) v3 and had it looked on for repair and it was really fried, I would go with a bigger amp if running the subs
