Does your audio turn off every time you turn your speaker level up?
Well…
Not to worry because you’re not the first to experience this.
Long drives with disturbed jams are surely irritating and that’s why we’re here to help!
This problem might be caused by several factors, let’s tackle each and every one of them. We’ll look at the many difficulties and solutions that may be useful to your situation. To learn more, keep reading.
Factors That Affect Car Stereo To Cut Out At High Volume
Radio Shuts Off And On While Driving
Alternator, Amplifier, And Voltage
If the car speaker keeps turning on and off, the issue might be with the amplifier or alternator. The alternator possibly isn’t charging the batteries sufficiently. The drain on the speaker grows as the volume level rises, causing more charge to be extracted, and finally, the car stereo is turned off owing to a lack of power. When the current drain ends, the voltage rises again, resulting in a new cycle.
Solutions
To begin, measure the voltage across the batteries with a voltmeter. If the number is less than 11.5 volts, the battery is the problem.
To reduce the power drain, consider adjusting the frequency and bass settings. Otherwise, you’ll need a heavy-duty alternator or a battery to meet the power demands. This strategy is recommended if money is not a concern.
Because the battery levels are lowering, performing diagnostics with this issue usually results in each measurement cutting out at a lower loudness every time a new reading is taken. If there are additional devices connected to the supply, then a heavy-duty alternator and battery may be necessary to provide a constant supply of power.
The amplifier may simply be unable to meet the power needs, or there may be too many power-sucking devices attached. If you’re on a budget or simply want a fast repair, then consider lowering the frequencies and bass settings to make the power draw more balanced.
Poor Soldering Of Ground Level Connections And Head Units
Speaker wires are frequently soldered throughout the manufacturing process. Poor ground connection soldering can have a significant influence on the amplifier’s capacity to draw power, perhaps resulting in audio cuts. Pre-installed fuses in the head units are another concern. Performance abnormalities are caused by blown fuses.
Solutions
Check for a blown fuse using a multimeter set to ohms. The testing leads should now touch the fuse caps, and the reading should be taken. If reading is received, then the problem is not caused by a blown fuse. If there is no reading, then you may need to replace the fuse.
Turn off the power supply to see if a blown fuse is the source of your problems. A multimeter tuned to ohms (electrical resistance) and testing leads is required. Next, tap the metallic fuse caps with the multimeter’s testing leads and record the measurement. If you get a reading, the problem is unlikely to be a blown fuse; but, if you don’t, the fuse has blown.
If your fuse has blown, all you have to do now is acquire an appropriate replacement and reset the stereo system.
Car Speakers Cut In And Out
Too Many Output Connections
Having too many output connections might be an issue at times. Only a limited number of speakers may be powered via car stereo.
Solution
You can upgrade to a higher-quality amplifier or car stereo. The newest versions’ higher-quality materials will also assist.
To keep things balanced, replace a cheap amp with a more powerful one and a stronger ground unit. Using high-quality materials allows you to boost your bass and improve your car audio experience. Older models may just consume more pore, much as an older car consumes more gas.
Improperly Installed Wires Gauges
The car speaker may switch off and on due to problems with the gauge connection. Make that the gauge connections are the right size and are correctly attached. If the wire diameter is too thin, then insufficient power will be delivered.
For example, supplying 150 watts of electricity requires a gauge size of 12 and not 10 or 14. Connectivity troubles caused by loose wires could also be the culprit.
Solution
Connectivity issues might also be caused by carelessly placed cables. Tighten all the wires without harming them as a result.
Damaged Or Eroded Wiring
If you’ve just begun having problems with your speaker, then the issue might be a broken speaker wire. Traveling through harsh terrain and areas might induce this. The environment also has a significant effect. Corrosion and rusting are serious problems if you live near the water.
Speakers Cut Out Randomly
Overheating Of The Power Unit
The car stereo unit consumes electricity, which increases when it is in high volumes. Overheating speakers are caused by faulty wiring connections.
Solution
As a result, you must ensure that the cables are appropriately positioned. If not, you may have to resolder them.
To resolve this issue, open the deck and inspect the wires, making sure they are in their proper locations and not crossing over. Resoldering or retaping may be required if some are out of place.
Steps In Stopping Speakers From Cutting Out
Turn off the audio/video (A/V) stereo receiver on the A/V receiver. Check that the speaker cables are properly connected to the speakers and the amplifier or receiver for audio/video.
Turn off any electrical devices that could be interfering with the speaker’s voice. Remove any electrical wires that are within three feet of the speaker.
Speakers’ Clipping Causes
When an amplifier is forced to provide more power than it is capable of producing, clipping happens as a result.
When the maximum power supply voltage is reached, it is difficult to increase the incoming signal without producing changes in its form.
This signifies that the signal has been amplified but in a highly distorted form.
Car Stereo Smoking Source
It’s an issue with the right channel if your car radio is smoking and not your power source, but your pre-amp or output stage. If one side of your speaker cables (or speaker) seems to be shorted, you should look them over for a possible short.
Process To Do When Car Subwoofer Cuts Out At High Volumes
The causes for subwoofers going out might be slightly varied. If your subwoofer is cutting out at high volumes, follow the steps below to diagnose the issue:
- Verify that the subwoofer is powered and the amplifier is grounded.
- Verify that the amplifier is not in protected mode.
- Make sure the subwoofer and amplifier have the same impedance.
- Examine the voltage drop across the amplifier’s power cable.
- Make sure the amplifier isn’t overheated.
- Check the amplifier gain level to ensure it is not set up.
- Check to see whether the subwoofer has blown.
Subwoofer Bass Fade Out At High Volume Reasons
The volume level affects bass fading, so if you turn up the volume to 110%, anticipate the bass to drop as the trebles take over. Those aren’t trebles at all. This is a distorted sound effect, so be careful not to turn up a high volume on the head unit to the maximum.
Subwoofer fading can also be caused by a faulty RCA connection at the subwoofer input or receiver output, or a broken RCA cable. It can also happen when the impedances of the subwoofer and amplifier do not match, causing the amp to have not enough power.

Frequently Asked Questions
What causes an amp to cut out at a high volume?
A shorted signal from the amplifier or a shorted speaker from the sub is the two most common causes of my protection circuit turning on.
What would cause car speakers to cut in and out?
Loose ground connections are typical. When the ground wire isn’t connected properly, the noise might create a variety of issues.
What causes the radio to cut in and out?
The connection between the antenna and the car radio could be broken. You’ll experience audio and sound issues when this happens. This degrades audio quality and may cause radios to stop often.
Conclusion
It’s certainly inconvenient to have a blown speaker at high intensity. It can also be time-consuming to address because car audio that switches on and off frequently could be caused by a variety of factors. Even for smaller electronics like vehicle stereos, resolving the problem is difficult, and a process of elimination to find the source will be required.
If you are not comfortable addressing the problem yourself, get it serviced by specialists. If your automobile was purchased new with the audio unit installed and is still under warranty, take it back to get it checked out.
