Why Car Speakers Do Not Work After Rain?

Have you ever observed that after it rains, your vehicle speakers stop working? Sounds recognizable? One of the frequent problems is having moist speakers, however there are a few typical causes of this. After it rains, car speakers won’t function because the moisture might short out the speakers. The speakers may rust or mildew as a result of the humidity, which can potentially harm them. As a result, your speakers will ultimately cease operating if they are exposed to rain or extreme humidity.

Why Do Car Speakers Stop Working When It Rains?

When raindrops get into the car door and onto the speaker magnets or terminals, automotive speakers frequently cease operating after it has rained. If the positive and negative speaker terminals are near to one another or the speaker wire is broken, moisture from the rain may short circuit the speakers.

When water gets into touch with the internal components of the speakers, such as the voice coil or magnet, this problem frequently occurs. Even though such elements are protected by the speakers, basic speakers, especially older models, lack a sealed basket and are not waterproof.

The dampness can also harm the speakers by rusting or mildewing them, both of which are dangerous. Rust on the metal components or connectors can lead to electrical issues like a short circuit or decreased current flow, which will ultimately cause the connections or the speaker to overheat. However, mildew can harm the speakers by blocking them or destroying the cone. For speakers with paper cones without a protective coating, this is very dangerous.

If you frequently drive in the rain or much worse, during a rainstorm, if you reside in a region with high humidity, such as one near the coast. In certain circumstances, speakers and other components of the automotive audio system are more susceptible to mildew damage.

What to Do When Car Speakers Not Working After Rain?

You should initially check the door speaker terminals to make sure they are not damp or damaged if your speakers cease operating after it rains. If so, you should wipe them down with a dry towel. Next, look for any evidence of damage on the speaker wiring. The cables must be changed if they are frayed or damaged.

Look attentively at the door panel’s rounded edges. Speaker wires there are susceptible to damage owing to frequent door opening and shutting motions. The speaker wires in many older vehicles may be in poor condition, therefore it is time to repair them even if the majority of modern cars have thick rubber protection.

If the cables and terminals are in good shape, the problem is probably the result of water damage to the speakers. In this situation, you must take the speakers out and allow them to completely dry before using them once more.

You might be able to clean your speakers with a solution of water and vinegar if they have mildew damage. But first, let the speakers dry, and then measure with a multimeter if the damage is serious. If it is, you will need to purchase new speakers.
