If your radio will not turn on at all then it is probably the fuse. Some speakers also have fuses too, if it wasn't a fuse then the speakers would probably sound torn. To check the fuse it depends on your car, look in the manual on how to change the specific fuse. Many modern cars have fuse boxes under the glove box on either the passenger or driver side. The fuse should look somewhat like a flat, transparent house plug, in the middle of the transparent plastic there is normally a connected wire and if it is broken the fuse is blown. If you have a fuse box you can compare with another good fuse or just look up an image of blown auto fuse.
Just remove the fuse and look at it.
