Why Does My Car Stereo Pops When Turned Off?

Everybody loves hearing music while traveling. Many people feel that music sounds better when they are on the road. Car travel gives us an excellent opportunity to catch up with the latest sounds. And enjoy a spot of musical nostalgia whilst taking in the sights. But, what if your car stereo pops when turned off, it can be really very frustrating. 

As the recent study has said that music preferences show that 58.8% of participants listen to music in the car purely because they love music. Others say they play music in the car because they like to sing during their journeys and also because it makes them feel shorter.

In this article, we’ll talk more about popping and crackling in speakers, the likely culprits, and how to fix the issues.

Why Does My Car Stereo Pops When Turned Off?

Speaker crackling or popping is almost said to be caused by a connection problem. Someplace between your amplifier and your speaker driver. There’s a bad wire which is causing the driver to move abruptly, causing interference.

There is also a possibility that the popping sound is caused by a grounding issue, or just for the simple fact that the amplifier needs to turn off before all the other equipment.

The main cause of speaker popping and crackling is interrupted current. Speakers are transducers that convert electrical energy that is audio signals into mechanical wave energy (sound waves). Audio signals are electrical signals with alternating currents.

Any kind of interruption with this alternating currents signal will cause the issue of your car stereo pops when turned off. When you switch off the power to your amplifier. It’s power supply will collapse asymmetrically which will cause the amplifier’s output to be at an indeterminate state. When it should remain at zero DC.

If your amplifier has an output relay and the popping. It is mostly noticeable when you turn it off, the problem might be in the bias of the output transistors, causing a DC drift to increase to a a significant level. This could be also heat related and the DC drift increases as the output stage heats up.

What To Do If You Face The Issue Of Your Car Stereo Popping?

A break in the car’s stereo circuit or a loose connection will cause the issue of popping or crackling sound from the system and that can be annoying and dangerous to the health of your speakers. This popping is a surge of electrical current jumping over a broken or bad wire connection, or a surge in your output settings from the amplifier.

Step 1:-

You will need, determine which speaker or speakers that are causing the problem. If the error is coming from more than one speaker. The issue will generally be in your harness wires or speaker wires or issues in your amp or equalizer. If it is only coming from one location, then you will want to check the wires and hardware of that specific one first.

If it is just an error coming from one speaker. Then it is likely not an issue with the amp or channel outputs on your stereo. If the noises are coming from multiple speakers, than you will want to check your amp outputs and channel settings. As they could be pushing too much current through the speakers causing the popping noise.

Step 2:-

If the noise occurs from multiple speakers, you will want to check the wires coming from those speakers, or the connection where those speakers hook into your sound system. If you have tried manual setting adjustments and you are still getting the noise.

You will want to check the wiring of your speakers to the stereo to make sure they are not getting grounded out somewhere. You need to check the wires coming from those speakers, or the connection where those speakers hook into your sound system.

Step 3:-

If you notice that the popping noise is only coming from one location, it is likely that this one speaker has a broken wire or connection. Simply use your tools to take the speaker out. And then check the connecting wires on the bottom for mechanical defects.

Step 4:-

If you have checked all these things, repaired all wires and connections, but you still hear the popping noise. Try connecting a different speaker of the same grade to that channel. If this alternate speaker doesn’t show the same sound error, than your speaker needs to be replaced.

Step 5:-

If the speaker you’re testing also makes popping noises, then your issue is in the wire harnessing for that speaker channel, or a deeper problem with either your amplifier or stereo system itself. In this situation, you will likely want to have a professional look at your system.

Therefore, you can solve the issue of your car stereo pops when turned off stereo by following these steps.
