AMP Problems

I have a pioneer amp and pioneer sub. I hooked thim up in my 05 trailblazer this weekend. Everything worked great for about a half an hour then I started blowing fuses. I don't listen to it very loud. I just like the added boost. I put another set of 25 amp fuses in it and it worked for about 30 minutes. Blew fuses. OK. So I trased the lines going from the amp to the speaker and there was a bad spot in the line. I replaced it and then I replaced the blown fuses. Now I don't have any sound... The light on the amp is on but about every three seconds the light blinks. I didn't notice it doing that before. anybody with a solution?

How can i fine the fuse that goes to the gas tank meter.

May have blown an output transistor. Remove the wires from the speaker terminals and see if the problem still persists. If the light comes on with no load, it will need servicing by a technician.
