A car radio will have at least one fuse to protect the unit from things like power surges or other electrical issues. If too much current is sent to the audio system, this fuse will blow out and disconnect the circuit to save the main radio. On newer models, there are a variety of fuses for the entertainment system.

What size fuse should I use for car audio?

How do I know what amp fuse to use?
B Calculate MINIMUM FUSE AMPERAGE by multiplying product amperage rating by 125%. Minimum fuse amperage provides more protection for the wire but may result in nuisance blows. Example: 80A x 125% = 100A. C Choose FUSE AMPERAGE near the middle of this range.
What size fuse do I need for 12v?
if the device load is known in watts, divide the wattage by voltage-(i.e 100watts divided by 12v = 8.3 amps) -use 10 amp fuse.
