Why do I need a fuse for my car radio?
All car radios require at least one fuse in order to operate, but depending on the make and model in question (as well as the trim package for the vehicle), your radio may have multiple fuses.

Why does my amplifier keep blowing a fuse?
You need to look for any bare wire while insulation and trim it back so that insulation could be done properly without causing continuous blowing of stereo fuses. In other common cases, the wire to the battery is grounding that blows a fuse due to a hot connection before ruining the amplifier.
How much does a fuse affect audio output?
Moving on, Bob Cordell is his great book “Designing Audio Power Amplifies” did measure fuse THD in an audio output stage. It’s section ‘13.11 Fuse, Relay and Connector Distortion’ page 268. “At 20 Hz, amplifier distortion due to the fuse is calculated to be 0.0033 %.” 1] AC power supply.

What happens if you have a bad fuse?
If the fuse is bad, upon retrieval and inspection the wire inside of the fuse will broken, burnt, or otherwise disconnected.

How do you replace a fuse on a car radio?
Check the fuse. If the small metal bar in the center of the fuse is burned through, you must replace it with a similar fuse of the same rating (color). Replace the fuse. Place a new fuse of the same color and amperage rating into the slot from which you removed the blown radio fuse.
