Common Car Audio Problems

There is nothing more irritating whilst driving your car than car audio problems . You may be travelling on some country roads or stuck in traffic and all of a sudden the music will stop. I personally find one speaker broken on the other side of the car the most infuriating.

Car audio problems are usually caused by two issues. The first being old age where the electronic component has simply aged after prolonged use. The second cause is where aftermarket parts have been installed correctly or are faulty.

The car audio complications are split into two categories that are radio and speaker related. This troubleshooting guide will be updated on a regular basis to become the ultimate car audio fault finding guide.

Why Is My Car Radio Not Working?

If your car radio is not working then the speakers will of course not work too. Your car radio may be a double din head unit or a single din head unit but they share the majority of the same problems.

The operation of a cars radio begins from the alternator whilst running or the battery when the car is switched off. With the wiring (mostly underneath the dashboard) connecting the radio to the speakers and power source to be able to produce audio.

All radios require fuse(s) to avoid harmful high power surges and high quality cars that want more power for his or her high wattage loudspeakers could have an amplifier. Power should be likely to all areas of the audio circuit for right running from the cars sound system.

Car Radio Broken – Complications and Solutions

  1. Fuse offers blown .
    The most frequent trigger for radios not really turning on and may be confirmed by using a voltmeter on the radios power and ground connection. OEM radios fuses are usually located in the main fuse panel box . If its an aftermarket radio, its usually located as an inline fuse protecting circuit. Therefore, check behind the radio (likely) or behind the dashboard (unlikely). Fuses are relatively cheap and should be changed first rather than other expensive “potential” fixes.

Radio intermittently turning off .
One of those irritating issues that is usually difficult to problem solve as it will work sometimes and not the other. If the screen is certainly turning off aswell as the audio, then this might mean the top unit isn't getting more than enough power. If it transforms off when heading round a part or on the bump, this might imply that a connector is usually loose at the back of the unit . This would not be a fuse issue as there would be no power all the time. If the wiring is usually all connected correctly, check the ground connector that attaches to your vehicle. If this is loose or there is rust around the connection, consider a new surface connection on your own car.


  • Faulty Mind Device.
    Not really the most frequent radio issue because of technological advances. Nevertheless, you might be unlucky more than enough to truly have a brand-new faulty head device or the existing radio is merely aged.



Which means you have just installed your new and expensive radio but there is no audio from your speakers. The first thing you should do before checking wires is usually to check different audio inputs . Anything from the air, CD participant, AUX and even more. When there is no audio arriving through the audio speakers on all inputs, you might have a issue.

The probably reason behind no audio in the speakers is normally disconnected/damaged cables or the bond towards the amp. A cable from the top unit towards the speaker is rather common with fresh sound builds. Its most unlikely that every loudspeaker will break at exactly the same time, so usually do not proceed replacing every single speaker in your vehicle.

The ultimate way to test the loudspeaker wires can be to operate a short-term loudspeaker cable from the top unit right to the loudspeaker itself. There is absolutely no stage ripping the wiring funnel until you're sure the loudspeaker wire reaches fault. You need to remove interior parts like the door cards to gain usage of the loudspeakers.

The usage of a multimeter can also prove useful when testing for problems such as polarity. This can be achieved by switching to DC Voltage, which the best automotive multimeters should feature.

Another way to test your car speakers is by unplugging the wiring harness from either the head unit or the amplifier. You are then able to use the positive and negative wires of the speaker against the positive and negative of a car battery. If the speaker wire is in working order, you should hear a pop/bang from the speaker.

Car Loudspeakers Broken – Complications and Solutions

  1. Radio offers power but no audio .
    Normally, this is because of two primary causes both concerning wiring. Cars with an amplifier will need to have a 12v sign connector (blue/white) for this to function, which is frequently neglected with audio installations. The more prevalent reason is loudspeaker wires becoming broken or have poor link with either the loudspeaker or wiring circuit.

Head Device Configurations .
As ridiculous as it noises, the settings such as the default volume level, fade and pan, balance and more may be set incorrectly. They could have even been set this way as a joke by your friends, so check the settings out before looking at the speaker wires.


  • Speaker Crackling or Popping .
    Usually due to age, the speaker can break down and start to crackle. Of course, a bad connection or poor input quality (AUX/CD) can cause a crackling sound. To see if the loudspeaker itself reaches fault, basically swap the route of the loudspeaker. If the crackling sound is still from the loudspeaker, you know that loudspeaker is damaged.

Top quality audio installation will probably have best car amplifiers to be able to get the very best audio. This being stated, the amplifier is among the first factors you should check if you are having troubles. Powerful car subwoofers are often connected up to an amplifier and if it also isn’t working, the amplifier is usually more than likely the culprit.

Car Audio Installation Costs

Installing a single din or double din head unit is a relatively simple job when you have the correct equipment such as for example radio removal tips . The very best radio removal tips usually come being a set having a few dozen mixtures. Without the radio removal key units, you will have a hard time eliminating your radio.

The cost of installing a radio should be no more than $100 maximum . It is as simple as removing the radio using the secrets, pulling the din connector and other wires from the aged unit and putting them into the brand-new unit. I strongly suggest that you try setting up your radio yourself.

Always make an effort to prevent having a free of charge or really cheap audio install. The self proclaimed audio installers will hurry the job so that as its not really their car, they'll be as tough because they like. The prior owner of my E Course clearly didn’t value the walnut hardwood when removing the air.


Setting up car speakers is normally slightly harder as you will need to not only remove and install the new speaker but cautiously handle the interior .

The best car loudspeakers will last much longer and be less troublesome, consequently we always recommend doing your study.

The interior of the majority of cars is very difficult to remove and requires tools to remove panels such as the door cards off. Be prepared to pay ranging from $40 to $80 dollars per loudspeaker depending on your vehicle.
