I have an MTX Thunder amplifier that has been working great for a few months and now it has stopped working. The LED light on top is flashing and I dont know whats wrong. I checked the web site but it doesn't say anything about the flashing LED. What do I do?

 

is it a steady blink? Or is it random? If its random it could be a bad/worn out ground and the power keeps turning on and off.

 

Steady blink. On for 3 seconds off for 3 seconds

 

When ever the light is on I can hear a faint humm from the Sub. but it stops when the light goes off.

 

bad ground, like flip said.

 

bad ground def

 

Not necessarily, could just be a bad power source connection as well
I once somehow got water in my fuseholder and that was the problem
