Car Radio Fuse Blows: 9 Causes & Solution

Car Radio Fuse Blows
Car Radio Fuse Blows [CAUSES & FIXES]

When your car radio fuse blows, it can be incredibly frustrating. Not being able to listen to music or your favorite podcasts while you’re driving can make the commute feel incredibly long. Most people don’t know what to do when their radio fuse blows, so they end up without music on long trips.

But what causes car radio fuses to blow in the first place? More importantly, how can you fix the problem, so it doesn’t happen again? Don’t worry, though. Keep reading to discover how to find the root of your fuse issues and, more importantly, how to fix them.

What is a Car Stereo Fuse?

A car stereo fuse is a small piece of metal that acts as a barrier between the voltages in your car’s electrical system. The fuse is designed to “blow” or melt if the voltage in the system gets too high. This protects your car’s electrical components from too much voltage damage.

When your car radio fuse blows, it means that the voltage in your car’s electrical system is too high, and the fuse melts to protect the system.

Types of car stereo fuse

Cylindrical fuse

Types of car stereo fuse

A cylindrical fuse is the most common type of car stereo fuse. It is a small, cylinder-shaped piece of metal with two wire leads sticking out of the top. The cylindrical fuse is placed in a holder attached to the car’s electrical system.

Blade fuse

Blade fuse

A blade fuse is a thin, rectangular-shaped piece of metal with two wire leads sticking out of the top. Blade fuses are usually used in newer cars. The blade fuse is placed in a holder attached to the car’s electrical system.

ANL Fuse

ANL Fuse

An ANL fuse is a large, cylindrical-shaped piece of metal with two wire leads sticking out of the top. ANL fuses are used in cars with high-powered stereo systems. The ANL fuse is placed in a holder attached to the car’s electrical system.

What causes car radio fuses to blow?

A blown car radio fuse can be frustrating. Here are a few possible causes.

A short circuit

The most frequent reason for a blown car stereo fuse is a short circuit. A short circuit is caused by a break in the electrical flow between two points. This break can be caused by a loose wire, a damaged wire, or a bad connection. When the electrical flow is interrupted, it can cause the fuse to blow.

Wrong Amperage Rating

If you use the wrong amperage rating of a fuse, it can cause the fuse to explode. The amperage rating of the fuse is irrelevant in this case. The maximum current that the fuse can safely carry is determined by its amperage rating. A fuse with a too-high amperage rating has a chance of blowing.

Incorrect Fuse Size

What causes car radio fuses to blow

 If your car radio fuse blows frequently, you’re likely using the incorrect size fuse. Replace your car’s fuses in a timely manner, mainly if you live in an area with severe weather. A lower amperage fuse than the one specified may cause the circuit to overheat and melt the wiring insulation, possibly causing a fire.

Incorrect Installing

An often-overlooked cause of a blown car radio fuse is incorrect installation. If your new car stereo or other electronic devices aren’t working, you may have made a mistake during installation. A loose wire can cause a short circuit by causing the flow of electricity to be disrupted, leading to a blown fuse. Hire a professional to install your new equipment if you’re not sure how to do it yourself.

Increased resistance can cause the car stereo fuse to blow.

If the fuse of your car stereo keeps blowing, it could be caused by an increase in resistance. This can come from several sources, but a loose or corroded wire is the most common.

If you have a loose wire, it will increase the resistance between the two points it is connected to. When the current rises, it causes the wire to heat up and eventually results in the fuse blowing. If you have a loose connection, you will need to tighten it. You can do this by using a pair of pliers.

Corroded wires can also increase the resistance between the two connected points. This is because the corrosion will be a barrier to the flow of electrons. If the current increases, it will heat the wire and cause a fuse to blow. If you have rusted wire, you will need to clean it. You can do this by using a wire brush or by sanding the wire.

Faulty Connection with the Ground

One of the main reasons your car radio fuse blows is a faulty connection with the ground. A problem with the ground can cause a current to run through the system, eventually blowing a fuse.

To fix this, you will need to check all the connections to ensure they are secure and tight. If you find any loose, you will need to tighten them or replace them altogether.

Fault in Wiring

Fault in Wiring

If your car radio fuse blows frequently, it is most likely due to wiring problems. Check for any loose connections or damaged insulation in the wiring. It is also a good idea to check the ground wire for any loose connections. If the problem persists, it is best to consult a professional.

Internal Damage

Internal Damage

If your car radio fuse blows frequently, the unit is likely to have internal damage. If you suspect internal damage to your car radio, it’s best to take it to a professional for repair or replacement.

FAQ

What is the average cost of changing a car radio fuse?

Generally, a car radio fuse will cost between $10 and $20. The price of the fuse will depend on your car’s make and model, as well as the type of fuse required. If you’re unsure which fuse to purchase, it’s best to consult with a professional mechanic or your car’s manufacturer. Replacing a blown fuse is usually a relatively quick and easy task that almost anyone can do.

Where is the car radio’s fuse kept?

The interior fuse box is located beneath the steering column. It can be accessed by removing the cover on the underside of the dash. The fuse for the car radio is typically labeled “Audio.”

Do you have to remove the battery to replace the fuse?

You must turn off the engine and disconnect the battery before you change the fuse. If you don’t, the new fuse can blow as well.
