Ok i hooked up some subs. For some reason when they were playing, they cut off everything electrical. Dash clack, radio, speedometer, tach, everything. I replaced the blown fuse, but half of the tach and the speedometer are still out. What went wront with everything and how can i fix it?

 

check your wiring. sometime if you hook up the wrong wires it makes your electrical system do some crazy stuff. like, your running lights will stay on, or you have to have your running lights on to make your stereo turn on, and like you said your dash lights will be gone. check you 12v constant wire and also your illumination wire as well

 

I think you may be right, but i found out today that my reverse lights dont work either. I dont know what is going on? I still need some more info on how to fix it....
