When you go on a drive, it can be a very long route if there is no mode of entertainment. Especially the driver gets tired of boredom so he might need something as a mode of entertainment. Listening to music can be the best source.
Radio is so important for drivers that a huge aftermarket industry has sprung up around car audio systems. But what if sadly when you start with the vehicle and the radio volume keeps on decreasing? So in this article, we will be explaining to you the do and don’t while using the radio. Also the reasons for why my car radio volume decreases on its own.

Reasons Why Car Radio Volume Decreases On Its Own
Following are the reasons to troubleshoot if the volume level of the car radio system raises or lowers by itself. Check whether these are the symptoms you are facing and fix them using the steps.
1. Your Car Is In Motion
When your car is not in motion, the radio might function properly. But as the car starts running by, the volume of the car goes up and down. Stand still cars do not face this problem. A car radio will have at least one fuse to protect the unit from things like power surges or other electrical issues especially when the car is in the running state.
Because much more power is generated in the overall system so if too much current is sent to the audio system for any reason, this fuse will blow out internally and the electric continuity will be uneven. The reason behind the problem with the radio might also be like the fuse is damaged as covered above.
2. Loose Or Damaged Wires
If your radio volume decreases on its own then it might happen that any wire from the car radio is a bit loose and needs to be tightened. Locating a loose wire in a very complex system can be a bit tricky but the best start you can give is at the back of the stereo. If the radio was not professionally installed then goes without saying that the connections are obviously loose or poorly made.
The wiring for the power, intermittent power, antenna, speakers also must be right for the audio system to work correctly. If any wires are loose, frayed, or corroded you will need to cut, strip, or also replace them back in place. When the speakers get old, it eventually becomes less effective.
Replace the radio over a period of time. Check for the ground wire. If it’s corroded, clean the corrosion and then bolt it back.
3. Antenna Not Receiving Proper Signal
It can be an antenna problem while the antenna is not getting the proper signal from the radio tower. The same symptoms will arise if the tuner has stopped working. Or, the car antenna itself is not able to catch that signal. So it can be said that antenna not receiving signals can be considered as a major problem for the car radio volume decreases on its own.
If a car’s CD music is properly audible to you with a normal constant sound and when the radio is turned on the volume becomes uneven then the antenna is damaged or the tuner. You will need to replace the head unit itself. Fix a stuck power antenna by replacing a bad cable. It will hardly take two hours if you have a basic knowledge of car radio mechanisms.
4. Battery Is Not Working
But sometimes the problem could be a tough task to fit. Like the battery is not working or it is fully damaged. If your car radio has an “anti-theft” feature that turns off the radio when the battery dies. So in these cases, if your battery is weak then this signal will interfere with the functioning of the radio. You might even need to put in a code to get the radio working again as normal. Because if your battery is weak, then it might kill the radio playing system.
A disconnected or dead battery is a common reason for car radios to give up immediately.
How To Fix The Car Radio’s Volume Problem?
Troubleshooting a car’s radio problem is not an easy task but instead of spending lots of money on your car radio give it a try and solve it yourself. Given below are the steps to detect and fix the issue.
- Locate the fuse panel of your car. Open the fuse panel and inspect the fuses which are in your stereo’s power. Check for the cracks, burnt glass near the contact. If you find something then the time has arrived to replace your fuse wires.
- If everything is fine with the fuse, check for the next. Look around the edge of the amplifier, sometimes the housing may touch the metallic part. Cover the area with fresh electrical tape.
- Check the Amplifier of the car. Remove the amplifier with the help of a screwdriver. Check if all the cables are properly connected or not. Remove all the wires from the amplifier check the connections and reinsert them again in the box. Tighten all the wires as mentioned above.
And if unfortunately if the problem arises from the antenna that is a very common site, then you need to replace the antenna itself because solving the problem of the antenna is tough and it will not long last even after you fix it.
Conclusion
Detecting why my car’s radio volume decreases on its own without any input given by you will be very annoying. So, if this problem arises you should fix this on your own. With the help of the above steps, check each part of the stereo individually.
By the above steps you will surely be able to identify why my car volume decreases on its own and you will be able to fix it. One from the antenna, fuse, amplifier, wirings will surely be faulty, and once the culprit is known, there you go!
