What To Do If Car Speaker Not Working On One Side?

Long drive with no Music? Just a horrifying ream to encounter, right? Whether you’re talking about car speakers, speakers of studios,  or maybe some cheap computer or TV audio system, worn out or broken speakers are always a big problem. When you realize that if you catch it fast enough, you can save the car speaker not working on one side. 

It is common problem for a car speaker to get damaged after a period of time.  This is often especially common in factory-installed original equipment (OE) speakers. Compared with custom speakers, their quality tends to be lower. As you are here, so you can almost certainly have some signs that you are dealing with a troublesome speaker. It may turn off during the magnification stage of the installation or have residues. We will solve all problems and provide you with professional guidance after you have accurately understood the transaction content.

How To Identify If The Car Speaker Not Working On One Side?

To describe any woofer, subwoofer, or tweeter that has a distorted sound or doesn’t work is described as speaker burned out. Even if it’s a pair of cheap headphones or a car speaker not working on one side it’s a mere thing to worry about, but what if it’s an important question in the exam but you opt to study? If the speaker gives out a distorting sound, no sound at all, or the speaker cone is torn we may address it as a blown-out speaker.

Disturbing sound results from a problem with the power source or a small tear in the cone, which can worsen. If there is any kind of electrical problem then you may face no sound at all too.

The main question is if you are not sure why the audio quality changes so subtle. You want to catch it before it gets worse and/or confirms that you have the simplest experience (for entertainment or worse, actual professional work).

Diagnosis Of Car Speaker Not Working On One Side

There are many components that can cause a car speaker not to work on one side. One must test all the components to get to the root of the issue

1. Problem In Speaker

To the problem first, turn off the vehicle and car stereo system, and link the left channel to the left amplifier and the right channel to the left output. Connect your right speaker to the output of the left amp (which you know works). Thereafter, turn on the sound and make sure the equilibrium is set to the exact middle.

Unless the speaker is really not functioning, the issue might be somewhere between the device and the amp. It might be a defective speaker, amplifier cables, or indeed any element in the current technique.

2. Door Panel Problem

The amplifiers in the automobile are mounted within the door panels, and it’s possible that perhaps the cables somewhere between the door and the doorway are creating the problem. This is mostly because of the frequent tension of shutting and leaving the door open.

Despite wire cables are typically protected by strong rubber scabbards, they generally fail with time. Unless the cables are not connected, you have a damaged wire someplace.

3. RCA Cable Problem

Follow these procedures to test any components between the head unit and the amplifier. Because only a bridge is available in our scenario, we should only need to perform this once. Begin by inspecting the RCA wires that link the intermediary component to your amplifier. Unplug the wires from the component’s output and then connect the good cables to the faulty side.

  • Remove the RCA wires from the component’s output.
  • Connect the RCA cord from the functional speaker to the non-working end of your car’s bridge. Because the left side is the functioning channel in this example, connect the left RCA wire to the top right of the crossing.
  •  Activate your vehicle’s audio system.

4. Problem In Wires

Provide some wire harness cables and fasten them to the speaker and amp to check the wiring. Unless the speakers function, the difficulty isn’t with the speakers but with the cables. during this instance, replace the old speaker cables with high-quality replacements. this could resolve the difficulty.

Furthermore, the warmth generated by the car’s electronics might cause the friction tape wrapped around the speaker cables to return loose.

5. Problem With Crossovers

The crossover is tested in the very same way as the RCA wires are. Move from the right to the left and conversely. Turn on the sound system. If the left channel continues to function but the right route does not, the fault lies with the intervening element. Determine if the element should be repaired or replaced.

Whereas if the difficulty changes to the left, the crossing is not the root explanation for the matter. Until the crossing, double-check the components, cut the speaker and reconnect the RCA wires to their original positions.

6. Problem With Amplifier

The following methods should be followed to determine whether or not the amplifier is the cause of the car speaker not working on one side:

1. Assign each speaker to one’s own channel, like the proper speaker to the proper channel and therefore the left speaker to the left one.

2. When connecting the wires, the car stereo should be turned off.

3. As soon because the speaker wiring is restored to its normal arrangement, disconnect and switch the RCA wires from the amplifier.

4. If the non-functioning speaker still doesn’t work while the functional one does, you’ll infer that the fault is with the amplifier.

5. If indeed the speaker begins to function after you flip the switch, this means there’s a problem between your amp and therefore the system, instead of the device directly.

How To Solve Broken Car Speaker On One Side?

After utilizing the above-mentioned test technique to diagnose the problem, problems such as replacing the speaker if the speaker is the source of the problem or fixing the amplifier if the vehicle speaker is not working with the amplifier may be addressed. You can take the appropriate actions based on your needs.

1. Fix The Speaker Cone

Whether the cones have torn or split from the material that surrounds them, you’ll glue it back alongside silicon rubber gel. it’s critical to use silicon since it’s stretchy; alternatively, you’ll produce another rip. For a blown-out speaker one can try two solutions: replace or repair.

One explanation for this is often that the amplifiers must be pricey enough to merit a repair, which incorporates re-coning. Re-coning entails replacing not just the cone but also the entire assembly, like the voice coil. And if we’re speaking about delicate, flat frequency domain monitors, you’re not watching a condenser mic.

2. Troubleshooting the Door Panel

This might also be an issue if your systems include a passive crossover between each speaker and the amplifier. You’ll need to remove the speaker from the door and connect it to your amp with short temporary wires at this point.

That way, you can check for problematic wiring while also testing the speakers. For example, if the speaker works with the new wires, the old ones are the problem. If the speaker works when connected to another amp channel, the problem is not with the speaker. In this case, you will need to test the other components by disabling the stereo system.

3. Check For The Crossover

After you’ve established that the bridge is defective, you may decide whether to fix it. It should be noted that establishing a crossover is a complicated process that necessitates some amount of experience. Consider collaborating with a professional technician to guarantee the safety of your system.

Select an audio system that swaps RCA wires from right to left or vice versa with the only crossover
If the left channel continues to work and the right channel does not, then the failure is an intermediate component. In that scenario, consider modifying or replacing the component.

4. Fix RCA Cable

To secure the cable, you need to make sure that the cable is worn or torn. Here’s what to do if the cable is frayed:

  • Remove at least a quarter of the insulation from the notch and cut the frayed section.
  • Slide the exposed edge of the cable into the tab on the back of the RCA input on it.
  • Apply the hot end of a soldering iron until hot Push the tab and end of the wire.
  • Touch the solder end to the joint until the solder flows through the joint.
  • Let the solder cool down before proceeding.

5. Set The Amp Frequency

Put each speaker on its own channel to do this. Connect the left speaker to another channel and the right speaker to the right channel. Disconnect the RCA connection from the amplifier and switch after the speaker wiring has returned to its original configuration.

This implies that you must connect the right wire to the left input before you switch on the automobile radio system and vice versa.

How To Prevent Car Speaker From Damaging?

The car speaker can get damaged or stop working on one side if the listed below points can be avoided. These are mundane things which everyone does in their everyday life/

1. Avoid Using Car Speaker Too Much

Distortion is the fastest way to destroy a speaker or burn amplifiers. The operator had adjusted the amplifier gains to meet the power output of your head unit. After the system is finished, you should not need to touch the gain knobs.

Turn to lower the level of your sound starts to crackle or distort at a high volume! Unless you want it stronger, you’ll need more strength, and cranking the distortion pedal gain knob won’t get you there.

2. Do Not Even Carry Your Supplies Or Trash

Do not let anything enter the sub. However, flipping groceries and laundry from moving subwoofers is harmful to them. Behind it, the ball of Gourrodani Nun Bowling can do a lot of damage. Install speaker brake ducts and keep cargo clean.

On the other hand, most automobile audio systems are well-equipped to survive the atmosphere inside the vehicle and the temperature fluctuations that come with it. You should never prick them or do anything to them until they wear out naturally after many years of service, and until you burst them by failing to follow step one.

3. Examine Your System Is In operation

There’s a lot of electricity going through those power lines, and if you have a huge system, there’s definitely a lot of vibration in your car. The ground should be inspected regularly to ensure that it does not rust firmly.

The same applies to battery connections and other distribution blocks in the system. If you want the music to continue, you have to run an electric current to continue.


Car speaker not working on one side is a common problem often faced by car owners. Fortunately, you don’t have to be a tech whiz to solve problems. However, speaker repair may require some skill, proper tools, and plenty of time. All of this is worth it because you will continue to enjoy the wonderful music while driving.

To test your speakers, change the 2 input lines from the amp or the rear of the speaker systems if you have a need to in the speaker box. It functions the majority of the time.

Stay safe and keep driving and enjoy your long drive with peaceful music.

Thank you
