This article applies to the Ford F-150 (2004-2014) and F-250 Super Duty (2005-2014).

Losing sound doesn't necessarily mean your car stereo needs to be replaced or taken in for a costly repair. In most cases, you can correct the situation with these five easy steps.

Step 1 - Check for systematic abnormality

Just to rest your mind at ease, double check to be certain you did not accidentally push something that might have affected the sound system without your realization. It could be that you bumped the mute button with your elbow or changed the balance of the speakers. You may have accidentally pressed the axillary button without any axillary devices plugged in.

Step 2 - Check that the antenna cable is plugged into the radio

You should be able to locate your antenna in the right rear window of your Ford F-150 or Super Duty. If you discover that it needs to be replaced, you can replace it yourself with the help of a wrench and a bit of elbow grease. If the antenna cable that's going in the stereo is loose, it could cut the sound off of the whole system.

Step 3 - Check amplifier's connections

This is a pivotal step if you have installed a sound system with a separate amp. A faulty amplifier can cause other electrical problems in your vehicle, specifically draining the battery. Check to be sure that the amplifier is connected to the system. If the connections are secure and you are still not getting sound, you will need to remove the amplifier and bench test it.

Step 4 - Bench test the amplifier

To bench test your amplifier, you will need to remove it from your truck. Set it down on a stable table and hook it up to power. Hook up the ground wire first. Then attach a remote turn on device. If the power light doesn't go on, your unit is dead. If it does, you have power.

Now you will need to check the amplifier's output by connecting it to a test speaker.

Then connect a tone generator to the unit via an RCA cable. If you get a tone, your amplifier is working. If you do not, your amp is in need of repair or replacement.

Step 5 - Reset your stereo unit

You can choose to pull the battery off or unplug the wires of your stereo in order to reset the unit. In order to reset the unit, you must locate the security code. After you unplug your negative battery cable or unplug the wires in the back of the stereo, wait a few minutes, then plug it back on. turn your ignition in the on position and wait for the word “code” to come across the screen. Once prompted, enter the code and the unit will be reset.
