Introduction

People often complain about their car speakers crackling. Do you face such an issue? A lot of times you are listening to your favorite tunes while driving on the road. However, a crackling and static disturbance in the speakers keeps irritating you. Needless to say, such problems ruin the music-listening experience of everyone in the car. 

It is vital to know that you can solve this issue easily. All you need to do is understand the base of the problem and implement solutions as guided. How often do you find yourself driving around town and listening to music yet a distortion sound ruins the whole trip? 

We live in a technologically advanced world where access to information is a blessing. You can always ‘Google’ an issue and see what its solutions are. Hence, it is vital to do thorough research about a topic to learn as much useful information from the internet as possible. 

What Is Causing The Static Sound In Your Car Speakers?

Sound travels through the stereo and speakers through electrical signals within the wires. It is safe to say that signals from other electrical devices can have severe impacts on the output, causing distortion. 

You have to realize that any component in your car that can generate an electrical field can lead to unwanted noise in the speakers’ output. These include the alternator, windshield wiper motor, battery, starter, and stereo components. 

All of these items are equally important to the adequate functioning of the car. Hence, removing them is out of the question. Now that we know the reason behind the annoying distortion you hear in your sound system, let’s talk about solutions. Although, you need to have patience and be very vigilant while detecting the primary cause. 

How To Overcome the Problem Of Distortion In Car Speakers? 

Here’s what you can do to solve this issue; 

• Track The Source First 

What is the primary reason behind the static noise in your car speakers? You can consult a stereo professional for accurate guidance. Although, you can also track the source yourself. There can be a wire touching the antenna, creating an electromagnetic interference field. 

Similarly, you might have an unshielded antenna cable causing unwanted static. There can also be issues with the head unit and other accessories. A good way of finding out the real cause is to play a song and then carry out a thorough examination of the entire sound system. 

• Take Out The Receiver While Playing A Song

Did you know that static noise is radiated into the system? The best way to confirm this is to pull out the head unit from the dashboard as a song is playing. If the distortion goes away after taking out the receiver, it is radiated static sound.

You can solve this problem by rapping the receiver in a magnetic shield foil. The cover plays the role of a barrier between the receiver and your car’s components that can cause radiated static sound. Try this solution and see if it works.

• Try Disconnecting The Speaker & Amplifier 

As mentioned earlier, wiring is often the main cause of static noises in car speakers. Therefore, you can disconnect the speaker wires from the amplifier while your car is turned off. Consequently, start the car and see if the noise is still there. Again, this means there is radiated distortion coming due to the interaction between the wires. 

You can wrap the wiring in foil paper to avoid this problem. Moreover, make sure to fit all the wires perfectly and see that none of them are broken. Ensuring the wiring is perfect contributes to eliminating the static from speakers in most cases. 

• Make Sure To Check The Car’s Battery & Alternator 

As we discussed, electrical components can also cause static in car speakers. If the noise remains after fixing the wiring, the next step is to check the vehicle’s electrical system. You can start by putting fluid in your car battery. However, if this does not solve your problem, go to a mechanic for further examination. Tell your mechanic to check the grounding as it can also cause static sounds in car speakers. 

People often have cars they do not use for a very long period. These individuals often face the issue of static noise in car speakers because of the ignition. You can confirm this by hearing for a tickling sound while accelerating the car. The noise will vary with speed so keep your ears out to notice it. Fixing the spark plug wires, distributor cap, and spark plugs coil can help you overcome this problem. 

Conclusion

Are you ready to start listening to your favorite songs on the road without any unnecessary interruptions? You may also have a faulty alternator if the static sound varies with the car’s RPM. We all want to have a seamless music-listening experience on the road while hanging out with friends and family. You can attain your objectives by following the tips and guidelines given above. Otherwise, consider consulting a car stereo professional.
