How to get rid of noise and background in car speakers
Crosstalk, noise, and background noise when the engine is running are common problems not only for novice car audio enthusiasts. They may appear after the system is turned on for the first time, or they may appear completely unexpectedly - “Yesterday it didn’t happen, but today it appeared. I didn’t touch anything at all.”
The network is full of lengthy materials on how to find the cause and combat these unpleasant phenomena. Go through the checklist below and in most cases you will be able to solve the background or interference problem.
IMPORTANT! Carry out all switching on a de-energized system. Not just turned off, but de-energized.
Speakers make noise when starting engine
Discussions Popular Subscribers Information. Good afternoon. Tell me who has dealt with this problem: When the engine is running, noise is heard in the speakers and subwoofer, and as the speed increases, the noise also increases. And when you turn the radio on and off, you can hear a loud bang in the speakers and subwoofer. There are 2 amps for the sub and front speakers.

Wiring Location
A common cause of hum, interference and noise is the close location of speaker and interconnect cables to the power cables, or to the standard wiring of the car (this also includes chargers, navigators, etc.). When installing, pull them along different sides of the body, and if intersections cannot be avoided, then place the interblocks and speaker wires at right angles to all the others.

Why does the radio sound?
There are several reasons why this problem may occur. The first of them is the occurrence of interference due to contact of the amplifier body with the body or unreliable antenna shielding. In this case, when listening to a radio station with a mediocre signal level, a squealing or crackling noise will be heard when the engine is running. If you press the gas pedal, the frequency of the strong background will increase in accordance with the engine speed.
The background often appears due to the induction of high-voltage discharges created by the ignition system of a gasoline engine. Also, the level of crackling noise from car media system speakers increases due to the use of low-quality high-voltage wires and faulty spark plugs. The cause of a monotonous squeak or squeal from the speakers may be a faulty generator. Interference provokes sparking brushes, worn commutator plates, and a short circuit in the stator winding.
Also, a strong background appears due to a malfunction of the radio, for example due to the drying out of the filter capacitor in the power circuit.
In this case, the radio freezes and reacts sensitively to all sources of interference in the car, including the DVR or radar detector.
Some media systems have a line wire fuse, which is placed between the ground on the board and the side terminals of the RCA sockets. When the negative wire of an amplifier connected in this way leaves, this fuse blows so that current does not flow through the interconnections of the radio.
In this situation, the linear outputs turn out to be ungrounded, which is why the radio sounds in any operating mode.
The interference is induced on the cables connecting the amplifier to the car radio. Other problems include loose connectors or damage to the screen shell. If there is strong interference when starting the engine, then the starter is to blame. Brushes can also spark in it.

The speakers are noisy when starting the engine. Such a problem: When starting the engine, the speakers and subwoofer begin to make noise, as soon as the tachometer needle rises above the speed, everything plays smoothly, and when turned off, it plays without noise. The noise is as if something is knocking in the speakers. Maybe the problem is with the generator, it produces little current? Ilm what could be the matter? Thank you in advance! Lyokha B4.
The reason for the appearance of additional background when the engine is running
Owners of Chinese Pioneer car radios sooner or later still encountered bad sound in the car. This can be described as a slight breakdown of the radio, which makes listening to music inconvenient. When any additional background noise appears from the speakers, the car owner immediately thinks that the radio needs to be changed. There's no need to rush. You first need to figure out why the radio is making noise. Next, we will consider the reasons for the appearance of unnecessary noise produced by the speakers.
The first option is the appearance of a background when you turn on the radio, this means that the antenna cable wire going to ground has come loose. You don’t have to do anything complicated here, you just need to screw it into place. Second, if additional noise is heard when playing CDs or other digital media, then most likely the wiring shielding from both the radio to the amplifier and to the speakers has been damaged. That is, the outer sheath of the cable, which protects the internal electromagnetic field emitted by the wires from the influence of external fields on them, is broken.

The manifestation of electromagnetic pulses is possible in the area of a broken or exposed wire. Third, if by any accident you pull, damage or even tear off the line output or input wires, then the line output fuse blows. And when you turn on the radio with the engine running, a loud howl sounds through the speakers. With such a breakdown, absolutely all interference emitted by electrical equipment installed in the car and even interference from a switched off DVR are captured. Well, the fourth, the most “harmless” let’s say, is bad contact on tulips.
Squeak and noise from the motor in the speakers

Advertising on the website. Order an advertisement. Thunder82 Regular. There is such a problem, when the radio is on, when you press the gas pedal, a whistle is heard from the speakers. I think it's a bad contact to ground. Can you tell me where the mass attachment points are? Adv0kaD Online. Alex RR Forum member. If the whistle is only on the radio, then the antenna is to blame. If it’s on cassettes or disks, then the power supply is to blame. To begin with, it would be nice to find out where the speakers are connected, to the tape recorder?
Most likely not, but for a separate amplifier, ’98 after all. An amplifier can also provide background. If there is no amplifier, then it is enough to install an interference filter for car radios on the power supply. The weight can be checked simply: connect the radio casing and the car body with a wire in any place where there is bare metal.
What kind of radio is it worth? Audi Concert radio. Whistle on any source. The front speakers are connected to the radio, the rear speakers are connected through a built-in subwoofer. If you turn off the system, the whistle disappears. The sound of the whistle changes with speed. What kind of filter is in the column? Where can I find it, what is it responsible for? Is it possible to change? Nailsun Forum member. If the radio and amplifier are original, then there is no cable with tulips. The cable from the radio to the amplifier comes with special connectors. If you pull this cable out of the amp and the whistle goes away, then that’s the problem.
If the whistle remains, check the power supply to the amplifier. The cable is laid along the car body next to other wires and picks up interference from them. On one machine I looked for signal wires in this cable and ran them with a separate shielded cord. The whistle is gone. Well, yes, it’s better to put the power and acoustic ones on opposite sides of the cabin.
Take the rear speakers out of the doors, look at them, if they have a processor, some kind of hat on the head of the speakers, then there are capacitors on it, put other speakers and that’s it. Most likely there is power supply separately for each speaker. Most likely they filled it in when they tinted it. It seems to have cured me. I disassembled the amp that was in the subwoofer housing, oxidation had started on the board from the screws, cleaned it, and reassembled it. I didn’t hear any noise, I’ll have to drive around and listen.
Bummer, the whistle has decreased, but is still present. Interesting too! It happens that after a small bump a whistle starts, depending on the speed it increases or decreases.
But I only get whistling from the rear speakers! Sometimes it also disappears after a bump, can the contacts on the rear speakers come loose or is the problem deeper? Tapok I live here. I don't know how it is here. Previously, on other machines, it was treated by installing a filter box that came with the radio. Speakers without processors. I installed a power filter on the radio - the situation did not change. The whistle remained. You must log in or register to post a message.

Troubleshooting noise-producing problems
The first case, when listening to the radio, you will just need to tightly screw the wire coming from the antenna to ground. Second case, if the wires are damaged, look through all the audio wiring and replace the damaged section. It is best to throw the wire intact without additives. The normal option would, of course, be to lay special audio cables specifically designed for this.
The third and probably the most basic point, where you don’t need to go without knowledge or without a specialist, is the fuse. First you need to determine what is wrong with the fuse. We close the negative line wire to the housing; if the background disappears, take it to the service center. Well, if you decide to do it yourself, then everything is in order:
- First you need to remove and remove the top cover of the device.
- We find the line output fuse; on Pioneer radio boards it is marked with an exclamation mark and looks like an SMD resistor with the letter “P” painted on top.
- If you don’t find the same one, then we change it in the proven old-fashioned way - we solder in several “strands” of copper wire, popularly called a “bug”. If a short circuit does occur, such a jumper will easily melt without causing harm.
- We check for functionality.
- We put everything back together in reverse order.

It will take you about 25-30 minutes. But keep in mind that you will not receive guarantees for the work performed from anyone. If your radio burns out after such actions, only you will be to blame.
At the fourth time, crimp the tulips.
Car radio tulips
If the radio is playing when the engine is off, then you just need to thoroughly solder the linear output contact to the ground contact. And just in case, crimp all the contacts that are in the radio connections.

For some reason, I always thought that the “crosstalk” came not from the genes, but from the high-voltage ignition distributor system.
Many people have noise when the engine is on, but for me it is constant and not. Did they start working after that in another car? Also check the voltage in the on-board network with the engine turned off and running. If in And when they returned to their cars, they did not start making noise in them?
What to do if the radio sounds when the car engine is running
Guys, help me out. I installed the Blaupunkt GTA amplifier and temporarily connected the Radiotehnika s30 speakers to it, after installation, these speakers made noise with the engine running. The higher the engine speed, the louder the sound. With the engine off everything works fine.
Forgot your password? Author anebesniy, Hello teammates. The problem is the following: when the car is started, the background noise from the engine can be heard in the speakers, maybe I connected something incorrectly? Why does this happen and how to fix it. Thank you in advance.
I connected the amplifier with the engine running and the extraneous noise resembles an itch with a squeak, but with the engine turned off everything is ok. Decibel channel Are the speakers humming?
By ermak, August 3, in Head units. Who can tell? Measuring the resistance from the minus of the linear ground wire results in 0 ohm. Does this mean that the fuse or filter in the radio has blown? The engine noise just started to appear, the head pioneer will they carry out repairs under warranty? It was strong, it was wound up to the linear guide on the cassette player, as they do with 88 peonies, the crackling went away, but the general background remained
