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 car radio stop working after a jump start?

For instance, if your radio stopped working after a botched jump start, the radio—and other delicate electronics—could have been fried. If you’re lucky, it might just be a fuse, and if you’re not, then this will just have to serve as a lesson as to how important it is to hook up jumper cables and battery chargers correctly.

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.

Why does a fuse pulsate in an amplifier?

OK, so about forty years ago I watched a fuse pulsate to the bass beats in an amplifier. It was a fuse in line with the speaker, and for speaker protection. Fuses react to current flow and they heat up when it happens.

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.
