Why Car Stereo Has Power But No Sound From Speakers?


Listening to music, audiobooks, or podcasts is one of the most excellent ways to avoid boredom while driving. It also increases your focus, making you more attentive on the road.

Turning on the car stereo and only to realize there is no sound coming out of the speakers is annoying. But, why can your stereo be powered but you do not hear any sound from the speakers? Let’s find out.

Generally, when you have powered on your car stereo, and there is no sound coming out of the speakers, the problem is most likely to be a blown fuse or bad wiring. It can also be a problem with the damaged speaker or short circuit within the audio system.

Tip: For the quality sound from the car sound system, you not only need good speakers and radio. The critical role also plays the quality wires and the proper connection of all elements with each other. 

When searching for the radio harness, those with the best quality are from Metra or Scosche, but the excellent power and speaker wires I found are from KnuKonceptz.

In this article, I will put together all facts about missing sound from the speakers while connected to the functioning car stereo.

Causes and Solutions to a Car Stereo That Has Power But No Sound From Speakers

A Blown Fuse

Like other electrical appliances, the car stereo is bound to have a fuse that protects them in case of a power surge and other electrical complications.

When the car’s electrical system releases lots of power to the audio system, it can blow away the fuse.

When the fuse is blown, it cuts the power supply to the stereo to enhance its safety. At this point, when you turn on the car stereo, there will be no sound produced by the speakers.

You should head directly to the fuse to check its functionality when you note such an instance. However, checking the car fuse requires basic knowledge about voltage or the electrical continuity meter.

Car stereos such as the Pioneer AVIC have the fuse located at the backside of the radio.

Note that once you have realized that the problem is the fuse, replacing it will get your car stereo working again. So how do you replace a blown fuse? Have a look at it! 

Replacing a Blown Fuse in a Pioneer AVIC Car Stereo:

Before you begin doing anything, power off your car engine to prevent things such as short circuits.

To avoid doing a lot of work, read through the car manual since it has all the directions. After locating the fuse, you must check if it has been blown or is OK to be used.

Use a fuse puller to remove the fuse, and you do not have the fuse puller, you can also use tweezers or needle-nose pliers to get the job done.

When replacing the fuse, remember to replace it with the exact one as the burnt one.

After installing, turn the key in the ignition to the accessory point and turn on the car stereo to verify if it is working. 

Once you hear the sound coming out of your speakers, please turn off the stereo and cover the same way it was initially.

Faulty Speaker Wiring or a Faulty Speaker

When the speaker wires are not connected, expect no sound when you power on the car stereo. Also, your speaker might be exposed to wear and tear due to aging, thus calling for a replacement.

The car stereo speakers are designed with an incredible vibe that helps them produce high-quality sound waves. Unfortunately, the older the speakers get, the less effective they become.

When this problem continues in the long run, there will be no sound produced by the speakers when you power on the stereo. 

How to Replace Faulty Speakers

You don’t have to be an engineer to replace a faulty speaker. All you need is a guide that will help you fix the problem. Begin by removing the damaged speakers by removing the door panel.

Ensure that you have turned off the engine to prevent power from running to the speakers. After accessing the speaker, disconnect all the cables and remove the speaker.

One thing to check when the speaker is removed is to ensure the connectors have a solid fit to the wires. Otherwise, you may risk the sound quality and potential short if one of the wires falls off.

Loose Wiring

As your car gets old, the car’s wiring becomes loose, affecting the general functioning of the car components, especially the car stereo.

The most common problem that causes the wiring to become loose is the vibration and bumps during driving.

At some point, you will realize no sound is coming out of your speakers, even after powering on the car stereo.

How to Fix Loose Wiring

To fix loose wiring in the head unit, you need to gain access to the backside of your car stereo. This might be complicated since most car stereos are installed inside the dashboard and require complete disassembly before you will be able to reach the wiring harness.

When you have the radio unmounted from the dashboard, take the voltmeter and check all ports and end of the wires for any breaks. Also, check every wire connected to the head unit and tighten the loose ones.

Go ahead and check if there are any loose connectors inside the dashboard.

Repeat the same procedure on the speaker and amplifier wires. After completing the process, turn on your car stereo to check if the problem is solved. 

Conclusion

Turning on the car stereo with no sound coming out from the speakers is a frustrating experience that affects most car owners.

However, this guide should help solve the problem and enhance the well-being of your car stereo.
