I have a 94 coupe and the radio fuses always blows up. I would put in a new one, start the car then after a few seconds the fuse would blow. I have no idea why it's doing this? Any ideas?? Thanks

 

you probably have a bad ground or maybe some wires touching. is it an aftermrket radio?? did you install it yourself???

 

see what else is on the fuse panel using the same fuse. one time i had this problem and it was the wrong sized bulb in my dome light. check little things like that because it might be something simple.

If you own a multimeter check the amps being fed to the fuse block and also voltage (while the engine is on). This will tell you what your dealing with. I'm thinking that if it's not a bad ground your alternator and it's internal regulator might be going bad.

-Be sure to replace the old fuse with the correct type.
