The most likely reason for your radio’s sudden death is a blown fuse. All car radios have at least one fuse that protects it from power surges coming from somewhere else in the vehicle. The first thing you should do when your radio stops working is check its fuses and replace any that have blown.

If the alternator isn’t working as it should, your battery won’t have enough charge to start the engine, but that’s not the only problem you may experience. A failed alternator may not be able to provide enough power to the spark plugs, which could make the engine stall while you’re driving.
How do you know if your car battery went dead or your alternator went out?
Jumpstart your car. If you can turn the engine on, but it dies shortly thereafter, your car alternator likely isn’t able to charge the battery. On the other hand, if you jumpstart the car and later on it fails to start on its own, it’s likely a dead battery.
