This is not good. Look for a fusable link under the hood. This is a safety device that will melt the link in case of a short. This device protects the electrical system when you do something wrong. Look for a wire that is partially melted or completely gone. That's where you will find the link. Now, the hard part is finding out what happened. Did you short something out? Better take a close look at all the work you were doing and see if you crossed any wires. Good luck.

Check for another blown fuse. The one on the back of the radio isn't the only one. Engine control fuse blown?
