Why does the radio turn off when you turn up the volume?

When listening to the radio in a car, especially with a fairly powerful audio system with good subwoofers and tweets, many devices experience malfunctions. Most often, car enthusiasts ask the question, why does the radio turn off when the volume is increased? Indeed, turning off the device when the volume is increased, especially when transmitting power to the bass, in a car audio system often turns off the radio.

What is the problem?

In this case, the device turns on again on its own without any problems, but operates at a lower volume. When I try to increase the volume, the situation repeats. Often, after turning off the radio, the user has to turn it on himself, which is very inconvenient.

Another situation that forces drivers to ask why the car radio turns off without warning is when the engine starts. Depending on the model and brand of the radio and the car, the shutdown can be short-term (when you start the engine, the device turns off for a couple of seconds and then plays again), or permanent, when you have to turn on the radio and adjust the sound again.

In more complex cases, after turning off the radio, the equalizer settings and other operating parameters of the device are reset, after which you have to re-configure the radio's operating parameters after turning it on. This causes a lot of inconvenience for drivers, and in order to find out why the radio turns on and off, you often have to remove the device from the socket and look for the root of the problem in the connection.

Let's look at the most common reasons for the radio turning off spontaneously and ways to solve the problem. They may consist of malfunctions of the audio system itself, as well as problems with the redistribution of voltage between all audio system devices in the car.

How to determine why the radio turns off and fix the problem

When listening to the radio in a car, especially with a fairly powerful audio system with good subwoofers and tweets, many devices experience malfunctions.
Most often, car enthusiasts ask the question, why does the radio turn off when the volume is increased? Indeed, turning off the device when the volume is increased, especially when transmitting power to the bass, in a car audio system often turns off the radio. What is the problem?

Why might the device break down?

For what reasons does the radio in the car not work and turns off when you start the engine, why does the device not turn on, does not see or read the flash drive, makes noise and stutters, and gets warm?

First, we suggest that you familiarize yourself with the main causes of malfunctions:

The system stopped working due to contamination of the internal mechanisms. If the radio is used in harsh conditions, dust and dirt may accumulate inside, and this, in turn, can cause damage to both the optical and mechanical components of the device. If a disk is stuck in your device, it is most likely due to contamination.
The cause of inoperability can also be mechanical problems, as practice shows, in this case the malfunctions are usually associated with the power circuit. Such problems may be caused by incorrect connection of the system. The system may not have enough power, causing it to turn off when the volume is increased.
The fuse has blown. As you know, fuses and relays are responsible for the operation of all electrical appliances in a car. It is possible that the fuse installed on the car radio itself has failed.
Failure of the device itself.

Malfunctions when connecting speakers to the radio

Incorrect connection of speaker wires to the radio connectors can also cause spontaneous shutdowns of the device. Especially when you start a car engine with a short-term increase in power, a short circuit occurs in the wires with an incomplete connection (input to the plug). To eliminate this malfunction, you need to visually check the contact level and, if necessary, insert the speaker plugs into the radio connectors more tightly.

You can also check the integrity of the wires leading to the speakers: turn on the radio at normal volume and disconnect the speakers one by one, increasing the volume. If the radio does not turn off when you increase the volume, then you can understand that the malfunction lies there. Replacing the speaker wire or contacting technical service helps.

Current leaks in the on-board network

If the radio turns off when starting the car, then the problem may lie in so-called current leaks. That is, when the ignition is turned off, there are consumers that discharge the battery. Overnight, due to these leaks, the battery can completely die. In order to solve the problem, you need to detect the leak and find its culprit. It can also be a radio, alarm, central locking and other systems.

Possible malfunctions and options for their elimination

So, how to get the head unit and repair the radio with your own hands, we suggest you learn about the main problems in the operation of the systems, as well as options for eliminating them. Where can I get my car radio repaired? In any specialized service center, but now we offer to find out how to repair such a system at home.

There is no screen backlight or the device does not turn on

What reasons can lead to such a malfunction:

In most cases, the reason lies in the fact that +5 power is not supplied to the device. In this case, after dismantling and disassembling the device, you should check contact number 2 on connector CN701. A voltage of 14 volts should be supplied to this contact; subsequently it is supplied to the collector elements of the transistors. If there is no voltage, then most likely you will have to change the transistors or zener diode.
There is no signal to turn on the power. In this case, diagnostics comes down to checking the voltage level at contact number 40 of the IZ901 controller. In addition, we also recommend making sure that contact number 3 is receiving a signal (video author: Dmitry Epishev).

The system turns on, but there is either no sound or noise

If the audio system is working, but there is no sound, or the sound is turned off or there is noise, then there can be many reasons.

They all depend on the specific situation:

The power unit starts, the car radio is activated, but there is no sound. If the sound disappears, it is most likely due to the lack of a Stand By pulse. In case of such problems, we recommend diagnosing the high-level signal at 4.8 volts - this means contact number 4 on the IC901 controller. If there is no sound, as well as no signal coming to the contact, the repair procedure will consist of re-soldering the controller. If the controller is intact and working, then it is necessary to check the functionality of the contacts on the power amplifying elements.
The next situation is that the head unit starts up, but the sound is noisy. If the sound is loud when you try to increase the volume, then first of all you should diagnose the presence of voltage at the so-called bases. The parameter value must not correspond to a zero value. If the voltage at the bases is zero, then in this case it will be necessary to replace the transistor components. In addition, the appearance of the background may be due to the inoperability of the button on the Mute control panel. If it really does not work, then the reason should be sought in the controller. If the controller is intact, but the sound is still incorrect, then check the functionality of the transistor element Q802.
In addition, such problems are often associated with the failure of one or several circuits on the amplifier device. If there is no sound, you should check all components located in the area from input to output on the circuits. There is a possibility that the circuit or capacitors have failed (the author of the video is the Gripells channel).

The radio does not play discs, memory cards, or the disc is stuck

Why doesn't the head unit play data from a memory card or disk, how can I get it out if it's stuck?

This malfunction can occur for the following reasons:

Most often, such problems are associated with the fact that the audio system does not perceive the format of the music track recorded on a disk or flash drive. There is no need to repair such a radio; you need to record the music in a different format.
Often, problems with playing tracks, as well as stuttering of discs, are caused by contamination of optical components, in particular, we are talking about the lens. If the system really does not function due to contamination, then this problem can be solved by installing a special cleaning disk in the drive. Before use, please read the operating instructions for the disc. If such cleaning does not help, then you can try to blow out the internal components of the system with a vacuum cleaner or disassemble the device and clean the optical lens with a piece of cotton wool.
The problem may be caused by a lack of laser current. In this case, you can get rid of the malfunction by adjusting the laser beam.
Problems with wiring or cables. During prolonged use, the screws in the device's structure may become loose, in which case they just need to be tightened. If there is a leak in the operation of the resistor elements, then the damaged parts must be replaced.

When you start the engine, the radio turns off: reasons

So, the owner gets into the car, turns on the instrument lights and radio, and then turns the key in the ignition.
The starter begins to turn the engine, while the instrument lighting dims to a greater or lesser extent, and the power unit turns off and restarts until the engine itself starts operating. As a rule, this happens if the engine is not yet warmed up. If you repeat launches in the future, but this time “hot” or after a slight preliminary warm-up of the engine, the radio will no longer turn off.

It is important to understand that when the power unit starts, the starter is engaged. This device is actually an electric motor that takes energy from the battery to rotate the engine crankshaft. At the same time, the starter is a powerful energy consumer. To put it simply, during operation of the starter, there is a sharp and quite strong decrease in voltage in the vehicle’s on-board network.

This voltage drop during startup is predictable. In this case, the main task remains to start the engine, and not to maintain the operation of other devices (heated mirrors and windows, headlights, radio, etc.). In other words, after turning the ignition key, all energy is sent to the starter.

If we talk about the radio, when the voltage in the on-board network drops, the power supply automatically turns off. This function is protective. The head unit itself contains a special program that restarts the car radio to protect it from freezing when the voltage drops.

However, it can be noted that this does not happen in all cases. For example, after the engine has been warmed up or the car has driven several kilometers after being idle, the radio does not restart when trying to restart the engine. Also, some power plants never turn off when starting the internal combustion engine, even if such a start is very difficult (the starter turns slowly, the dashboard dims, the headlights go out, but the music plays). Let's figure it out.

As already mentioned, the protective function of turning off the power supply at low voltage is programmed by the radio manufacturers themselves. In this case, a minimum “threshold” is established when the protection will work. This means that if the voltage does not drop below any value set by the device manufacturer, the head unit will not restart either.

In practice, everything will depend on the battery charge level and the condition of the battery. For example, the battery is slightly discharged, and the car starts in the winter after being parked overnight. Under such conditions, the starter will naturally need to turn the engine longer, since the engine oil thickens in the engine under the influence of negative temperatures, the fuel pumps and evaporates less well, etc.

The battery itself is also cold and consumes the remaining charge faster, that is, after a second or two the starter will turn more slowly, etc. It is quite obvious that all the “forces” will be devoted to starting the power unit, and a voltage drop in the on-board network will naturally occur.

However, after the engine starts and runs for some time, the battery replenishes the lost charge thanks to the operation of the car generator. The oil in the engine also thins out, etc. This means that when restarted, it will be much easier for the starter to start the internal combustion engine, that is, there will no longer be a significant voltage drop. In this case, the protection of the car radio will no longer work, since the voltage simply will not drop to the minimum required by the manufacturer of the head unit.

Lack of power supply

If the car radio turns on and immediately turns off by itself, the cause should be sought in the following faults:

Connecting an audio device to a power source with thin wires. If the cable thickness does not exceed 0.5 mm, the device will not have enough power. The voltage drop is so pronounced that the radio turns off spontaneously when listening to music at high volume.
Incorrect power supply connection. When the high beam is turned on, the radio stops working if the quality of the connection of the wires of the negative pole of the device is poor. When connecting the “plus”, the integrity of the wire leading from the ignition switch to the dashboard is often damaged. In this case, car owners simply clean and connect the broken ends. In this case, not only the radio does not work correctly, but also the speedometer. If erroneous codes appear when diagnosing the engine management system, the radio is connected to the power circuit incorrectly.

Reconnecting the device to the on-board network helps to cope with the problem. When performing work, cables with a thickness of at least 0.75 mm are used. To connect powerful car radios, use wires with a cross-section of 1 mm or more. The negative wire is connected as follows:

a pin located under the dashboard stands out and is cleaned with sandpaper;
take the end of the wire with a terminal of the appropriate size;
the terminal is put on a stud, the connection is secured with a nut;
The positive cable is connected to the car battery.

A connection made using this method is well suited for connecting powerful car radios and amplifiers.

Surge protection

Manufacturers of car radios, in an effort to extend the life of their devices, install voltage limiters. The overload protection system often causes the tape recorder to turn off when you turn up the volume. If the search for other faults does not produce results, the reason should be sought in the presence of a limiter. As volume increases, power consumption increases. When the maximum voltage is reached, the radio will turn off.

The specialists refuse to fix the problem. If you remove the protection, the device may break. If the owner still decides to get rid of the limiter, he will have to carry out the repairs himself. The work order includes the following steps:

Installation of amplifiers located between the speakers and the audio device. This helps increase the sound volume without changing the voltage in the tape recorder.
Checking the wires connecting the radio to the speakers. When identifying crushed or twisted cables, the cause should be looked for in them. Damaged parts of the system are replaced with new ones.

The radio stutters when the volume is increased. — Audi A6 Avant, 2.5 l., 1997 on DRIVE2

Hi all. I want to share my impressions of the time spent searching for a jamb due to the sound stuttering in the radio. It all started with the purchase of a Pioneer MVH-280FD radio. After the purchase, immediately near the store, I installed it in the parking lot in place of the standard radio. I think the pioneer, and even with increased power, will start blasting from all the speakers that were in the car, and whoosh. As the volume increased, she began to stutter and the sound was not very good. Before that, I looked at a review of it and the nuances during installation. Well, okay, I think it’s all due to the native low-power supply, then I’ll redo everything from the Akum. I arrived in the village, in the garage, and began to look at how to properly install the power wire. I lifted the back seat and saw three twisted wires, as I understand it, two tulips for the subwoofer signal and one thin one for turning it on. You're lucky; you don't even need to install a new wire or disassemble anything. However, after rummaging around in the radio compartment, I never found them there. I had to unscrew the right panel covering the rubber door seal and the right relay block. There I found the other twisted end of these three wires, pulled them to the radio, connected a thin one from the battery and to the yellow power wire of the radio through a 15 A fuse, as was in the instructions. But there was no result. Without thinking for a long time I decided that the problem was in the radio. I took it off and took it to the store. There, from the doorway, the seller began to say that it was all my fault and no one else’s, but I insisted on checking it, arguing that if everything was fine with the radio, then everything would work for them and I would go look for the reason elsewhere. And so it turned out that the radio played without problems from their power supply. Someone advised me to check the wiring of the speakers, as if they were shorting, but in this regard, everything was fine too. As a result, only after I tried everything I had enough imagination for, including connecting without a fuse to the direct line and with one speaker, and minus from the Akum to the direct connection to the body, it was found out that the loose connection of the yellow power cable of the radio was to blame for everything . After replacing this connection, everything worked as it should.

The problem is this: When a disc or radio is playing, at low volumes a hissing is clearly heard, which does not increase with increasing volume, that is, the music “masks” it... If you pause, the hissing stops. It doesn’t matter how the speakers play…directly from the radio or through an amplifier.

Solving problems with the radio automatically turning off on Android in standby mode

Another popular way of listening to music is Internet radio. There are many similar sites on the Internet, so everyone can find a radio station to suit their taste and musical preferences.

However, it happens that the radio on the Android turns off in standby mode. If you listen to the radio through any application, then you need to make sure that there are no restrictions on its operation in the background using one of the methods described above.

No less popular are specialized sites where you can listen to radio stations. If playback stops some time after blocking, you need to make sure that there is no limit on playback in sleep mode in the Wi-Fi network settings.

Another important factor is the lack of a stable Internet connection. Although experience suggests that 100-200 Kb/s is quite enough for radio, it is still worth checking the signal level.

Disabling music playback in the background is largely determined by the settings of the smartphone or application itself. The main reason is to save battery power. Although it’s easy to get around this limitation, you shouldn’t discount a banal software failure of the player.

How to turn off your Pioneer radio

A feature of a number of Pioneer radios is that they switch to “standby mode” instead of turning off, which causes several inconveniences:

In a parked car, the clock on the radio display lights up, and the buttons are also illuminated, which increases the likelihood of the device being stolen; When driving at night with the radio turned off, the driver may be distracted by the backlight of the buttons; Turning off the radio not completely leads to increased battery power consumption.

Select System from the list of partitions; Next, click PW Save; Turn off the radio using the OFF button; After these actions, it will go back into “sleep mode”. Press button “1” to turn off the radio; The clock display appears. Press button "4" to turn it off completely.

Such complex manipulations will only need to be carried out once to turn off the Pioneer radio, after which it can be completely turned off by pressing the “1” button.

Please note: If the radio settings are reset, for example, when disconnecting the device from the battery, you will need to repeat all the instructions described above again

Insufficient battery power

If the radio constantly turns off when the volume increases, the reason should be sought in the low power of the battery. When the engine is running, the battery power drops sharply, which is why there is not enough voltage to operate additional devices. Installing capacitors on radios helps solve this problem.

You should look for problems in the battery itself. Malfunctions in the operation of audio devices occur when using an old-style battery. The battery may need to be fully charged. It is also recommended to check the wiring connecting the battery to the on-board network.

Starter

Sometimes the battery may have nothing to do with it, and the problem may be hidden in the starter. During the operation of the latter, its parts are subject to wear. If the starter bushings are worn out, the shaft may get stuck in them and more energy must be spent to turn it. Hence the shutdown of most electrical consumers.

To correct this malfunction, an inspection of the starter is necessary. It is necessary to check the brushes, commutator, replace worn bushings, and lubricate the mechanisms. After such a revision, the starter will work like new, which means it will need less voltage.

Causes

Often the reason that the radio “stutters” when the volume increases is a lack of voltage. The car's generator and battery provide the required voltage, but the current is not enough to fully power the device. You can determine whether this is the cause of the disturbances using a voltmeter.

Overheating of the output stage amplifier can also cause disruptions in the operation of the device. The junction of the input stages with the cooling radiators is lubricated with thermal paste designed to remove the generated heat. The paste gradually dries out, causing its conductivity to become worse.

In this case, the device for listening to music in the car may fail or switch to protective mode; In this case, “stuttering” may occur.

Another possible reason for a car radio breakdown is a problem with the drive. Information may not be read correctly from the disk.

The essence of the problem

Lack of voltage

First of all, if the sound on the radio stutters when consumers are running from the internal network, this may be caused by a lack of supply voltage. That is, the car’s generator produces the necessary voltage, the battery also powers the internal network, and the current is not enough to fully power the radio. You can check this by connecting a voltmeter and an ammeter and look at the values on the devices.

Then turn off the internal loads on the network and see what happens to the values. Consumers can be high or low beam headlights, a stove, fog lights, or a heated glass system. If after this action the sound returns to normal, then there is a lack of voltage.

Diagnostics

There are several ways to solve this issue:

An additional power supply system is installed, which operates according to a capacitor circuit and accumulates the necessary voltage for power supply. After that, the radio tape recorder is powered from them;
You can buy and install a sound amplifier, which is recorded separately and amplifies the incoming sound signal from the radio. In this case, there is no need to increase the sound on the radio to full power;
Go to a professional auto electrician for service, he will take the necessary measurements and advise what needs to be replaced. Perhaps your generator is damaged and is not producing the charge it needs.

Amplifier overheating

Another common reason for the radio to start stuttering may be overheating of the output stage amplifier.

It doesn’t matter whether the Pioneer, LG or any other radio tape recorder stutters, they are all assembled according to the same structural diagram. The output stages are assembled on powerful transistors that emit a lot of heat. They are mounted on cooling radiators, the connection point is treated with thermal paste

Thermal paste helps to better transfer the generated heat to the radiator

They are mounted on cooling radiators, the connection point is treated with thermal paste. Thermal paste helps to better transfer the generated heat to the radiator.

Over time, during operation, the thermal paste dries out and heat conductivity is impaired. The transistors overheat and the radio may go into protective mode, and in a bad case scenario, burn out altogether. In some modern radios combined with video systems, the output stage is assembled on microcircuits that are even more sensitive to overheating. If they fail, restoration work is quite expensive, and parts for certain models are supplied only on order.

In order to avoid such situations, it is recommended to remove the radio from its standard installation location without disconnecting it from the car. Switch to playback mode, turn up the volume and after 15-20 minutes touch the side walls with your hand, on which the output stages are usually attached. If your hands feel very hot to the touch, you should change the thermal paste.

You can do this yourself by buying a tube of thermal paste. Then, using a Phillips screwdriver, carefully open the covers of the radio. Carefully inspect the insides; you should notice transistors or output stage microcircuits screwed to the side walls. They unscrew from the walls and bend a little.

Using a flat object, you need to apply a thin layer of new thermal paste into the resulting area, having previously cleaned all areas of contact from the old paste. If this sounds scary and incomprehensible to you, contact any auto electrician who will quickly and inexpensively change the thermal paste.

When operating a car in winter, very often the heater works constantly. The radio is installed very close to the heater radiator and may also overheat as a result. It would be advisable to remove the radio and make some simple thermal insulation, using, for example, materials for bathhouses. This will remove excess heat and the radio will stop heating.

What thickness (section) of the wire is - I'll look tomorrow. but I think 8 or 10 Ga

How securely are the contacts grounded, are there any short circuits (including acoustic wires) - Apparently not. But the ground is secured to the floor with a large bolt and washer. There are no short circuits. The previous ones are normal.

Does the amplifier have enough power (the battery must be intact!) A capacitor is desirable! — The battery is almost new, there is no capacitor (but several years ago no one installed them and nothing seemed to be cut off).

gets cut off by fast-paced bass attacks in music? - Yes.

It could also be that the amplifier goes into protection against overheating or overload with the input signal (check gain) - what is Gain? (well, I don’t know)))))

Is the volume at this average volume low, or is it already filling your ears? )) - The volume is comfortable, believe me, I want to add more but I can’t (((

Are the lights turned off at all? What kind of mafon?, try it when arming

Another option, try waiting for 10-15 minutes, maybe less, first the tidy will go out, and then the mafon, although he was probably already waiting judging by your post

I don’t think this has anything to do with it, but removing the terminal helps in 50% of obscure glitches. I’ll remove the terminal in the morning. Do you think it might help? The other day I deleted my account, maybe that’s the reason(

What to do

Many malfunctions due to which the sound in the car radio is lost can be eliminated independently, without resorting to the services of a service center. For example, checking and correcting the sound parameters of Pioneer radio tape recorders, as well as other brands, is carried out in accordance with the instructions for the device.

How to set up a radio

To adjust the sound, press and release the volume control. If the audio is lost on one side, you need to correctly adjust the stereo balance. To do this, press the car radio volume control until the display shows “BAL” and a number. By turning the knob, the stereo balance is set to zero, in the center. The volume of the left and right sides of the car audio system will be the same.

To configure the parameters of the Pioneer audio radio, press the “Audio” button to select the “Fad” function. After this, the “left” and “right” buttons set the balance between the left and right sides, and the “up” and “down” buttons set the balance between the front and rear channels of the car audio. You can configure the radio again by performing a factory reset. It is necessary to press and hold the “Reset” button, which is located on the front panel or under it, with a sharp object for several seconds. This procedure is carried out on a machine with the battery installed and connected.

Amplifier replacement

If the speakers are working properly, but there is no sound from the speakers, then the problem lies in the failure of the amplifier chip. In this case, you must have skills in working with a soldering iron and knowledge of radio electronics.

Since all parts inside the car radio are tightly installed, care should be taken to avoid the risk of accidental damage

First, the board is removed from the metal case and degreased on the reverse side. Then the faulty microcircuit is soldered off. After this, the seat for the new amplifier chip is prepared by thoroughly cleaning it from old solder. If necessary, the leads of the part are bent with tweezers and a ruler.

Soldering is carried out with extreme caution. Adjacent parts can be protected with foil

After installing the board in the chassis, the speakers are connected to the radio, power is supplied and operation is checked.

Stripping the loop

This procedure can be performed on radio tape recorders in which the nodes are connected to each other by cables. You need to prepare alcohol or acetone, a cotton swab and an eraser. Then the radio is disassembled and the latch securing the connecting cable is loosened. To avoid mistakes during installation, you should mark the location of the cable relative to the socket.

A careful inspection will determine the presence of dirt and damage. First, you should go over the contacts of the cable with an eraser. Then a fine cleaning is performed using a cotton swab dipped in alcohol or acetone

In both cases, care must be taken not to damage the delicate contacts. The reverse connection of the cable is carried out according to the previously made mark

If only one side of the speakers works

The cause of this problem is an incorrect connection of the speakers themselves or a violation of the stereo balance. Another reason for the lack of sound in the speakers of one side is poor contact in the car radio cable, which often occurs due to oxidation or constant shaking of the device.

Thus, you can determine why the sound on the radio does not work on your own. Making the necessary settings and troubleshooting will also not cause significant difficulties.

For many drivers, the radio in the car is an integral part of it. Because it allows you to enjoy pleasant music or just your favorite song during a trip. With such support, even the longest journey will not seem boring.
