Testing For An Rca Cable Problem
For any intermediate components between the amplifier and the head unit follow these steps for each one. We only have a crossover so we’ll just do this once. Begin by testing the RCA cables between the intermediate component and the amplifier. Unplug both RCA cables from the intermediate component’s output. Now plug the working channel’s RCA cable into the non-working side of the crossover. In our case the working channel is the right so plug the right RCA cable from the amplifier into the left side of the crossover. Turn on the stereo system.
If the right channel continues to work then you know the problem is in the RCA cables between the amp and the crossover.
If the right channel no longer works then you know the problem is not the RCA cables. Verify this by turning off the stereo system, plugging the left RCA cable from the amplifier into the right RCA output of the crossover. Turn the stereo system back on. If the cables are good then you should have output from the left speaker. You should not skip this verification step because it is possible for a problem to exist in both the cable and in another component.
Turn off the stereo system and return the RCA cables to their normal position.
If You Hear Hissing Or Other Distortion
Inspect the patch cables and speaker wires. If the cables that connect the head unit and amplifier run alongside any power or ground cables at any point, they can pick up interference that you’ll hear as distortion.
The same is true of the speaker wires. The fix is simple: Reroute the wires so that they don’t come close to any power or ground cables, and that they cross at a 90-degree angle if absolutely necessary. Using higher-quality cables or wires with good shielding can also help.
If you can’t find any problems with the way the patch cables or speaker wires are routed, unplug the speakers from the amp. If you still hear noises, check for a bad ground.
The problem might also be in the head unit or whatever else you use as an audio source. For more information on how to diagnose that type of problem, learn how to deal with ground loops in car audio systems and identify and fix other issues with your car stereo speaker.

Testing For A Speaker Problem
With the vehicle and the stereo turned off disconnect the speaker wires for both the left and right speakers at the amplifier. Now connect the left speaker to the right amplifier output . Turn on the stereo system and make sure the balance is set to the middle position.
If the speaker still doesn’t work then the problem is somewhere between the amplifier and the speaker itself. It could be the speaker wire, any of the wiring connections or a bad speaker. If the speaker has a passive crossover between the amplifier and the speaker this could also be the problem. At this point we’ll need to remove the speaker from the door and test it on the amplifier using short lengths of speaker wire. If the speaker works then the wiring is the problem. If it doesn’t work then it is indeed a bad speaker.
If the speaker did work when we put it on the other amplifier channel then we know the problem is not in the speaker and we’ll test the next component. Turn off the stereo system.
Why Does My Car Audio Have So Much Static
- Shoreline Community College
Anything that generates an electrical field can introduce unwanted static into your car’s audio system. The alternator, windshield wiper motor, and the components in a sound system generate different levels and types of noise and static. So, while it’s possible to isolate and fix the source of almost any type of car audio static, it often takes real work to find it and fix it.

Check Car Radio Wiring
This part is quite complicated because the car radio wiring passes through various parts of your car. However, one simple thing that you can do is to check the wiring with the naked eye and see if you find any physical signs of a short circuit like a burning smell, flickering lights, or metal on the wire.
Turn off the car and then wrap that wire with electrical tape so that it becomes insulated.
Another and my preferred method to check faulty wiring is by using a multimeter. Its easy. Just turn the multimeter knob to continuity, which is indicated by a small microphone symbol.
To ensure that the multimeter is working correctly, join metal parts of two leads together, and you will hear a beep. Take two wires and now place red lead on the wire and black lead on the second wire.
If the multimeter beeps, then the current flows, and the circuit is closed.
Hissing Popping Crackling And Buzzing Noise From The Car Speakers
When you turn up the bass or the gains in your speaker, it tends to create a buzzing sound. Plus, when something physically touches the cone, it causes similar buzz-like noises. If reducing the gains or bass does not deal with the trouble, your speaker may have reached its limit.
However, sometimes distorted voice coils can also lead to crackling or buzzing sounds. Always ensure that theyre not dysfunctional. Check for the ground wires for all the components in your cars audio system. These wires should be short and firmly tethered to the cars metal structure.
The obstacle might also lie in the cars electrical system. It sometimes results from old spark plugs and malfunctioning ignition components. You can contact your mechanic to fix these issues on the electrical side.
Other noise sources, like air conditioning, lights, cell phones, and similar, can also cause such buzzing or crackling noises. You can try to reroute the receivers wires to move them away from these noise sources.
Lastly, ground loops may also be the reason for this issue. To solve this, you can use a filter to avoid this problem. If it persists, sadly, you need new speakers.

Another Problem Might Be That Your Amplifier Is Outdated
At times an old amplifier produces horrible sounds such as crackling that is most commonly associated with static and this is even more worrisome as you have purchased the device to aid your speakers and you expect such transistors and capacitors to last you a long time.
Now one of the biggest issues with a device like an amplifier is that the connection by which the attachments hold the transistors and capacitors together might have gone loose. If theyve gone lose you dont need to chuck the entire speaker set out but simply get them reattached by a professional.
However if they have become corroded due to chemical leakage, then there might not be any possibility of saving it. Finally, because you are tweaking the bass setting when you use an amplifier, keep in mind that sometimes the distortion in your favorite song might not be due to a problem but merely a side effect of excessive vibrations produced by you listening to music at the highest setting. Try turning the volume down slightly and see the difference.
How To Fix Distortion In Your Laptops
The laptop speakers are relatively subject to distortion because of their small size and cheap quality. At high volume, the base produces crack noises. If your laptop starts to produce distorted sound, then low the volume of your laptop.
If this method doesnt work then there are other ways through which you can fix this issue. Troubleshoot the speakers of your laptops. You can do this by going to the playing audio option in the troubleshoot settings.
On your taskbar, right-click the troubleshoot sound problems option and by following these instructions your laptop will find the problem with the speaker.
You can adjust the volume of your laptop speaker to the one at which it produces less distortionFor Mac, go to the Apple menu and click System Preference. Select the equalizer option from the Sound option by this and you will see two options through which you can adjust the volume.
For Windows, go to the taskbar and right-click the Speaker option, and then select Open Volume Mixer. Now click the Advanced option and adjust the format to 16 bit 44100. The sound distortion will low than before.

How To Fix Distortion In Cars
You may face distortion in the sound system of your cars if you play the audio beyond its limit. But the wipers, air conditioners, and signal lights of your cars can also interfere with the audio of your speakers.
To have loud and clear music you have to turn down your speakers to 75% of volume. Ensure that other parts of your car are not meddling with the speakers if the audio is still distorted.
Keep your speaker on and turn off all of the components. Slowly turn on all the components, if the noise has become clear. By doing this you can find the component that is distorting the speaker of your car.
Another way is to dodge bass boosted music. The bass will distort extreme levels if it is unprofessionally added to the music.
Turn down the bass from the settings if you want to avoid distortion and want to play bass boosted music.One of the main reasons for distortion in your cars is that the cars dont have the best audibility. There are many parts of the car that restrict the audio heard by you.
The plastic made interior reflects the sound. The carpets and foam pads of the seats can absorb the sound. To have clear sound and to minimize all the factors you should install an equalizer to control the bass of your audio.
Loud Bass Noise Can Damage Your Car
Naturally, your health is the most important reason why you shouldnt turn thatvolume dial too far. Of course, thats not the only thing to consider here.You also need to worry about the shape of your car.
Regular noise in the middle and highregisters probably wont do anything to your car. However, bass sounds may actually speed up its deterioration. The metalparts your car is made of are always vibrating, thats inevitable. Between thesheet metal pieces and the various wires and other parts of the car, thatrattling eventually leads to certain areas weakening, rusting, or evenbreaking.
Incredibly loud bass noise can even make those vibrations visible to the human eye. In this video, youll see the lucky owner of a truly insane bass speaker setup lose consciousness after sitting in his car with the bass turned up. But before you see that, youll see how the noise is literally pulling the vehicle apart at the seams. And who knows whats happening inside the metal frame!
In previous articles about automotivesoundproofing, Ive explained how you mightprevent vibrations from affecting your car by using sound deadening mats.By attaching the adhesive mats to the sheet metal, youre adding to its bulkand making it less likely to wobble. Additionally, if you wrap up theindividual wires and parts that may bump into that sheet metal, you couldprevent them from hitting the surrounding metal.

Are Car Stereos Covered Under Warranty
Like any other consumer products, also car radios come with the manufacturers warranty.
A JL Audio, for example, provides a 90-day warranty of their products if installed by an unauthorized or by yourself.
However, if you install the same product at their authorized dealer, the warranty is extended from one year to two years.
If your vehicle is new, it will most likely be covered under the bumper-to-bumper warranty, which covers everything, including car stereos.
Suppose any damage occurs to your car stereo. In that case, it can be replaced by the company itself, provided the stereo is not connected to a product not approved by the manufacturer.
If you are using a used car or purchased a vehicle from a dealership, make sure to read the documents and things included in the warranty.
Many people use an extended warranty that covers the normal function of the car, but some of them exclude internal components. For example, since damage to the car stereo does not affect the cars normal functioning, it is not covered in the extended warranty.
Many authorized dealerships can provide you with a counter return of your damaged product. In addition, they can ship products directly to you after some days.
If you have a newly installed car stereo, then the warranty offers vary from dealership to dealership. Keep your warranty car at a safe place as it is the companys policy to provide compensation for your car radio repairs only if you have a warranty card.
Isolate The Speakers To Find The Culprit
Although speaker rattle can sound like it is coming from anywhere or everywhere, usually the problem is caused by only one speaker. By adjusting the fade on your audio system you can hear sound either from the front or rear speakers. By adjusting the balance, you can hear either left or right side. Play with these long enough, and you should know which one to blame. Then you can move on to actually fixing it.
Use the Owners Manual
Most vehicles come with a manual that is the size of a decent novel. Some manufacturers consider the audio system so important that the vehicle will come with a separate manual just for audio. Although I am sure that some people have never taken it out of the glove box, you should. Because to repair speakers, you are going to have to remove, and replace, door panels and possibly other coverings and moldings. Your manual should show you how to access all of the speakers in your vehicle.
Use of the manual will help you do the job quicker and easier. It will also save you from compounding the problem by breaking something or re-installing it improperly.
Tighten Speaker Mounts
Check and Clean the Connections
On the other hand, if the speaker terminals are so badly rusted that the brush is taking pieces off, you may have to consider new speakers or doing a little soldering to build them up enough to accept spade connectors.

Ruling Out The Amplifier
To determine if the noise is coming from the amp, disconnect the patch cables from the amp’s input. If the noise goes away, reconnect them to the amp and disconnect them from the head unit. If the noise comes back, check how they are routed.
If the patch cables are routed near any power cables, rerouting them may fix the problem. If they are correctly routed, replacing them with higher quality, better-shielded patch cables may fix the problem. If it doesn’t, a ground loop isolator may do the trick.
If you hear a noise with the patch cables disconnected from the amplifier inputs, examine the amplifier. If any portion of the amp is in contact with bare metal, relocate it or mount it on a nonconductive spacer made of wood or rubber.
If that doesn’t fix the problem, or the amp wasn’t in contact with the vehicle frame or chassis, check the amp’s ground wire. It should be less than two feet long and tightly attached to a good ground somewhere on the chassis. If it isn’t, install a ground wire of the proper length and attach it to a known good ground.
If that doesn’t fix the problem or the ground was good to begin with, the amp may be faulty.
