I had it in my car for two days and it quit working. The green power light in the side is off, and the protection light is off, but the red light on the top of the amp near the name is on. I checked the fuse under the hood and the fuses on the amp. I got it hook to 2 Hifonics HFi 12D4. What do you guys think about that, I only bought it because I heard good things around here.
