I have two amps in

Question

I have two amps in my car a 1100watt and a 800 watt both are almani.I have not had any problems with the system until now and I have had it for about a year.I have no sound what so ever from any speaker in my car.the music will come on for a couple of seconds and then fade out.I noticed on the 800 watt amp the green power light goes out and thats when the sound goes out as well.I thought it might be the fuses but if not does that mean the amp has gone bad?
