I have a 7.5 fuse that blew on me which was connected to my gauges EG. the light in my cluster. I cant see anything now my whole cluster light is turned off. I replaced the fuse and turned head lights on and heard it sizzle away again. What could be the cause of this short circuit.

I recently installed amp in my car. Everything was fine for the whole week till now.

Help Help Help. I cant drive in at nite now.
