A common problem with car audio systems is that the speakers cut out when bass hits. A bad ground connection usually causes this, or the speakers are not being powered properly. Knowing how to troubleshoot car audio systems is important before you need to.

If your car speakers cut out at high volume, it might be time to replace your car stereo. Or, maybe your car speakers are fine and your problem is with the radio or a faulty amplifier.

Whatever the case, this post about why do my car speakers cut out at high volume will explain why your car speakers might cut out at high volume and how to fix the issue.


If you have ever asked yourself why my car speakers stop sounding when I hit the max volume button, then you should know that several reasons can cause this. And if you aren’t careful, it can even cost you a lot of money.

In this article, I will reveal an amazing secret to the mystery of why your car’s speakers stop working when you hit the maximum volume button.


The actual source is the principal thing you should see while researching a sound issue. This could be a loose speaker wire, a broken speaker, or a loose connector.

On the off chance that the source is awful, you want to track down the wellspring of the sign and fix it. If the source is fine, you should look at other aspects to troubleshoot the problem.

Several hours of research led to the following factors as solutions to fix speakers that cut out at high volumes.

  1. Ground Wiring
  2. Voltage Drop
  3. Amplifier
  4. Levels of Gain Knob of Amplifier
  5. Speakers and Their Compatibility with Amplifier
  6. Inadequate Power Supply
  7. Weak Connection to Power
  8. Temperature
  9. Short Wiring to the Amplifier
  10. Bad Speakers
  • Ground Wiring

A simple way to check the ground wiring is to touch the negative and positive terminals of the Amplifier with your finger. If you feel a shock, then you need to check the wiring. It could be the negative wire that is not connected to the Amplifier’s chassis.

If you have a low-impedance speaker system, the current will be less likely to find its way into the ground. If you have a high impedance speaker system, the current will likely find its way into the ground.

Ground wires should be installed so they don’t interfere with the electrical current going to the speakers.

  • Voltage Drop

When you turn on your car stereo, it’s like turning on an amplifier. It requires a specific measure of voltage to work appropriately. If you have a 12-volt battery, you will need 12 volts to run the car radio. If your car battery only produces 10 volts, you will not be able to play the sound system.

When you start playing your sound system at high volumes, your alternator has to work harder to supply the same amount of electricity.

The problem is that the alternator does not produce a consistent amount of electricity, so if you crank the volume up too high, your car will be unable to provide the electricity your stereo needs.

It could be a loose connection or a bad ground. If you are using a stereo, you can check the grounds by using a multimeter and measuring the voltage at the speaker terminals. If the voltage is dropping, you will need to check the connections and make sure the grounds are secure

  • Amplifier

An amplifier is the heart of any audio system. It changes over an electrical sign into sound waves that movement through your speakers.

When you play a high volume song, your Amplifier can get overloaded by the sound waves and shut down. This could be brought about by a power flood, a free association, or just playing excessively clearly.

In the event that your amp is removing at high volume, it very well might be over-burden. You can analyze the upsides of the RMS wattage and impedance (opposition) in ohms.

High impedance means less current flowing, which means less heat. High RMS wattage means more heat, so make sure you don’t overload your Amplifier.

If you are having trouble with your sound system, be sure to check for loose or broken speaker cables. It is important to keep the speaker cables from getting tangled together.

  • Levels of Gain Knob of Amplifier

The gain knob of an amplifier provides a means to adjust the amplitude of the Amplifier’s audio signals. This knob allows users to increase or decrease the volume of the audio signals being outputted by the Amplifier.

volume knob the volume knob can be used to increase or decrease the volume of the audio signals being outputted by the Amplifier.

  • Speakers and Their Compatibility with Amplifier

You might need to remove the speaker cables from the speaker terminals. If the speaker wires are not damaged, then you can simply disconnect them. Then, you can check the watts RMS rating of the speaker and compare it to the Amplifier’s rating.

If you’re using an amplifier and speaker to create an audio system, make sure they’re compatible. For example, if you’re using an amplifier with a 4 ohm speaker, you need to pair it with a 4 ohm speaker, not a 2 ohm speaker.

This is because speakers have a nominal impedance rating based on the power they require. If you don’t match the impedance, you could experience problems such as overloading or overpowering.

If the speaker channels on the amplifier test are good, then it is likely that the speakers themselves are not the problem. The Amplifier may have been damaged or the connections may have been loose.

It’s important to double check the connections and make sure the power cables are snugly attached to the Amplifier.

To avoid this problem, ensure your amp has enough power to drive the speakers. For example, a 100 watts RMS amplifier should be paired with four 25 RMS speakers. If the watts RMS are incompatible, the speakers could be experiencing overpowering, causing shorts.

  • Inadequate Power Supply

An adequate wiring kit is critical to the efficient operation of the Amplifier. A good kit will provide enough copper wire to accommodate the amount of current required by the amp.

For example, if your amp is drawing a lot of current, the wiring kit will need to have enough wire to accommodate the amp’s power demands. If not, the amp will have difficulty providing sufficient current to the speakers.

A well-built amplifier can deliver amazing sound quality, especially when paired with a set of good speakers. However, if you’re using a poorly built amplifier, you may find that it can’t handle the power of a subwoofer and will struggle to get any low frequencies.

If your Amplifier isn’t up to the job, try a better-quality amplifier, and a better wiring kit.

  • Weak Connection to Power

There is a possibility that a weak connection to the power at your speakers, Amplifier or to the battery of your vehicle is the root cause of this problem.

  • Temperature

On the off chance that Amplifier is put in your trunk, it very well may be hot even before you turn up your sound system in light of the absence of ventilation. Also, on the off chance that you are clearly playing music, your Amplifier might get warm enough to trip the security circuits and shut down.

  • Poor Wiring

It’s important to check the wires. No one can really tell when a smidgen of wire could bring you a great deal of hardship.

If you hear an unpleasant buzzing noise while you are playing music, check the wiring of your speaker system. You may find that one of the wires has come loose and is touching another wire, causing an electrical short. Try to remove the offending wire to fix the problem.

If you notice that your speakers aren’t working, you need to do some troubleshooting. There are two possible causes for this problem: either one of your speaker wires has come loose, or you have a short circuit between the positive and negative wires.

If you hear a hissing sound, this is usually a sign of a loose connection. Try tightening the wire connections through a professional technician.

Short Wiring to the Amplifier

If your Amplifier’s power wires are too small, they will restrict current flow and create a voltage drop. This will make your Amplifier less powerful, which means your subwoofer will not be able to produce as much sound.

Bad Speakers

A speaker’s cone is what converts electrical energy into sound. If the cone gets too hot it may start to warp or crack.

It will usually pop when the sound is turned up, and it will begin to make a loud rattling noise or maybe speakers stop working due to the cracking of cone.


If walls, people, metal, or other objects interfere with Bluetooth waves between your speaker and your smartphone or tablet, move the connected Bluetooth device closer to the speaker.

The smartphone or tablet may experience issues when operating apps or accessing the settings screen.

Using short-wavelength radio waves, Bluetooth technology transmits data over short distances. When out of range, your wireless Bluetooth headphones will pause playback and the pairing will be terminated.

If you are experiencing issues with Bluetooth, connect your device to the speaker via a USB cable. Connecting your device directly to the speaker bypasses the Bluetooth signal and eliminates any interference issues.


The speaker wiring between the receiver and speakers can often cause premature shutoff of your unit. One strand of wire in the wrong place (causing a short circuit condition) will cause the unit to shut off at anything but very low volume levels.

There are also various reasons that can cause your speakers to turn off. Some of the causes include the following:

  • Short circuit
  • Weak battery
  • Poorly wired speaker wire
  • Damaged speaker wires
  • Poor electrical connection

If you want to have a good sound system, it is a good idea to check the connections. Check the connections carefully.


  • Sometimes, you may experience problems with your Car stereo volume when you drive. This is because the volume may drop off and rise back up. The reason for this may be that you are running out of battery power. You should make sure that the power cable is connected properly and securely.
  • You should also check the fuse box in the vehicle and make sure that it is working properly.


  • The speaker wiring is the cause of the problem. The sound can be cut off completely if there is a break or crimp in the speaker wiring. Bad wiring to the amplifier is one of the possible causes of the problem. The head unit could have failed if everything else was checked out.

Additional Tip

This is an exceptionally convenient tip for anyone who needs to add bass to their music. A subwoofer is a speaker that is intended to create a more powerful sound.


What causes a speaker to cut in and out?

Bad or Poor wire connection is one of the primary reasons for the speaker to cut in and out.

How do I know if my car amplifier is bad?

  • No sound while using the car audio system.
  • The sound system gives bizarre sounds.
  • Twist in sound from the system.

What can damage an amplifier?

  • In correct connection with the speakers.
  • Overheating due to hot climate.

What happens if Amplifier is too powerful for speakers?

If the amplifier’s power is larger than speakers, it can badly damage the speakers.

What happens if Amplifier is not powerful enough for speakers?

It can still bring damage to the speakers.


If you’re having trouble hearing your car’s speaker or even a conversation at high volume levels, there could be several potential issues mentioned above.

If you are using Amplifier in your vehicle, I recommend first checking the compatibility of Amplifier with Speakers.

The speaker could be defective or there could be a faulty or damaged amplifier in your vehicle, which is connected to the speakers. This is also known as “backfiring”, where sound is coming back through the Amplifier. There could also be a problem with the audio Amplifier or its wiring.

This can be caused by a loose connection, a loose wire, a loose jack, or a short circuit. A loose speaker wire connection could also cause your speakers to cut out.
