What To Do If My Ford Expedition's Sound Is Not Working?

You can do the following if your Ford Expedition's sound stops working:

Replace Blown Fuse

Find any blown fuse in your sound system wiring and replace it if necessary. It will not be difficult for you to change the fuse if it is situated outside the speaker box. 

In the event that the fuse is housed inside the speaker box, you will need to use a screwdriver to loosen the screws holding the speaker in place and remove the speaker from its housing in order to access the fuse. 

Any problem that was brought on by a blown fuse can be fixed by doing this.

Check The Signal Wires

Check the condition of the signal wire and determine whether or not everything is operating as it should. Another essential step is to determine that the signal wires have been correctly installed.

This involves ensuring that the wires have been pushed all the way into their respective ports and are not hanging loose.

MoveThe Speakers Away From Each Other

If you have an aftermarket sound system installed in your Ford Expedition, and you find that the speakers are located in close proximity to one another, the ideal solution is to move them away from each other.

If you have put your speakers on a wooden board that is located behind your back seat, you will need to obtain a new piece of wood and position your speakers in a manner that keeps them at a distance from one another. 

However, if you have already installed your speakers in a soundbox and you notice that they are constantly bumping into one another, you should mount the boxes so that they are further apart from one another. 

Fix Bad Wire Connections

If your speakers are not functioning properly due to an improper wire connection, it may not be necessary to go out and get new wires and then install them .

You can attempt to fix your speakers by checking the wirings. Look for bad wire connections and tighten any loose wires.

You can check for a bad connection by switching the two input wires of the speakers, which may be done either from the amplifier or from the back of the speakers, and see if that resolves the problem.

Call A Mechanic

The role of the mechanic is analogous to that of a physician in the field of automobiles. A mechanic can diagnose and repair just about any problem that may occur with an automobile, and this includes problems with the sound system.

If you run into a problem that is more complex than you can handle, contact an automobile expert. They will examine your Ford Expedition sound system and provide you with a solution to the problem.

Why Is My Ford Expedition's Sound Not Working?

There are many reasons why the sound system of your Ford Expedition is not working, some of which include the following:

Blown Fuse

A significant amount of current has the potential to cause harm to a variety of electronic devices, including sound systems. 

To prevent the sound system from getting damaged, it is a common practice for manufacturers to place fuses in the wire of the sound system that originates from the amplifier.

The Ford Expedition sound systems receive only a limited amount of power that is necessary for it to function correctly in this manner. Since some fuses are fragile, they can blow even when there is just a minor increase in the power.

The circuit of the wire is broken when the fuse in the system wire blows. This occurs when the amplifier provides the system with more current than it is supposed to deliver. As a result, the Ford Expedition's sound system stops functioning.

Defective Signal Wire

The head unit must send electric signals and data to the speakers in the sound system, and the signal wires are responsible for relaying this information.

Sometimes, even when the signal wires are plugged in on both sides (the amplifier and the head unit), the signal wire may not be plugged in correctly. Due to this, the wires have to exert more effort than normal to transmit electrical impulses from the head unit to the amplifier.

Consequently, during this process, the wires may keep sparking or missing signals, and after some time, they may go bad. 

Improperly Installed Speakers

Improperly installed speakers in your Ford Expedition may cause the sound to stop working. Magnetic coils, a diaphragm, a suspension system, and a frame are the many components that make up a speaker.

Placement of these speakers too close together, to the point that one's magnetic field tries to enter the magnetic field of the other, will cause the speakers to malfunction.

The speakers' forceful diaphragm movement is generated by a magnetic coil mechanism, resulting in deep, resonant bass and a robust audio experience. 

However, the magnetic field loses some of its efficacy when it is constantly forced to compete with another field, limiting its usefulness and, as a result, may stop working.

Wiring Issue

Wires have the potential to be the source of a problem in any situation where they are present. Preinstalled sound systems in Ford Expeditions rarely have wiring issues because they are tested extensively and made to fit the vehicle specifically.

However, when a car sound system is installed by a third party, sometimes known as an aftermarket installer, it is more likely to have wiring issues.

It's easy to make a mistake while installing custom audio, and some of them may not even be compatible with your Ford Expedition.

Additionally, the coil of a speaker has two inputs for wires. The colors of the wires are clearly delineated: red for one and black for the other. The reason for their varying colors is that they serve different purposes. 

Aftermarket sound systems may not come with color wires for the speakers, which can result in the wires not being connected properly.

Absence Of Speaker Wire

When setting up speakers, some manufacturers can make errors. They use short cables in a sound system, connecting the speakers directly to the amplifier or audio head.

A short wire installed in the sound system has the tendency to unplug itself from the amplifier or the sound box if it is even slightly displaced from its original position. The sound system is totally disconnected when this happens and will stop working immediately.

How Do I Reset My Ford Expedition?

To reset your Ford Expedition, do the following:

  1. While holding down the Seek up button, push and hold the Power button on the audio device until the display screen goes dark.
  2. Give the system about three minutes to finish resetting itself.
  3. Once you've waited for the required amount of time, you can turn the audio back on by pressing its Power button.

How Much Does It Cost To Fix Ford Expedition's Sound System?

Because a variety of problems can cause your Ford Expedition's audio to malfunction, the cost to repair the problem will vary. Fixing some issues can be done quickly and at a low cost, while others can't.

A diagnosis of the electrical system in a Ford Expedition typically costs between $88 and $111, while the cost to completely replace a car stereo system ranges from $200 to $500. Spending between $1,000 and $3,000 will get you a top-of-the-line system.

How Long Do Ford Expedition Speakers Last?

Ford Expedition speakers can last fors 10–25 years, although this can vary based on factors including how often you use your vehicle, how well you take care of the speakers, and the temperature and humidity of the area in which they are used.

How Can I Test My Ford Expedition's Sound?

Adjusting the volume in modern car.

Perform the following tests to determine the overall quality of your Ford Expedition's audio system:

  • Pay close attention to the sound waves or frequency.
  • Slightly modify the volume.
  • Listen for vehicle interference.
  • Take speaker placement and audio staging into account.

To Wrap Up

If your Ford Expedition's sound is not working, it could be a result of different problems. All you have to do is replace the blown fuse, check the signal wire, and fix any bad wire connections. You should contact a mechanic if you can't solve the problem by yourself.
