Sub and amp issue please help

I have two mtx thunder series 12" subs. A mpr-500 alpine amp has pushed them or at least 8 months and suddenly they don't produce sound. However, after switchin the speaker wires, RCA, remote wires, making the ground shorter, checked the power wire and all the fuses, the problem still remains. I got some sandpaper and removed the paint on my ground spot to get bare metal. After removing that paint, I tried the amp again and the subs worked for 2 seconds then cut out. I do not know what to do now. I used a signal light tester and the power wire, remote wire and fuses all are good.
