Common Causes Of Subaru Audio Issues
Subaru audio problems can be frustrating. Many drivers face issues with their car sound systems. These problems often have simple causes. Knowing common reasons helps fix them faster. Below are frequent causes of Subaru audio issues.
Power Supply Problems
The audio system needs steady power to work well. A weak or interrupted power supply can stop the audio. Battery issues or alternator faults reduce power. Loose battery connections also cause audio to fail. Checking the power supply is a key step.
Blown Fuses
Fuses protect the audio system from power surges. A blown fuse cuts power to the stereo. This causes the audio to stop working completely. Fuses are easy to check and replace. Regular fuse checks prevent sudden audio loss.
Faulty Wiring Connections
Wiring connects all audio components. Worn or loose wires cause sound problems. Corroded connectors reduce audio quality. Poor wiring can stop the system from working. Inspecting and fixing wires can restore sound fast.
Software Glitches
Modern Subaru cars use software for audio control. Bugs or glitches may disrupt sound functions. Software updates often fix these issues. Resetting the system can clear temporary errors. Keeping software up to date improves audio reliability.

Basic Troubleshooting Steps
Audio issues in your Subaru can be frustrating. Basic troubleshooting helps find simple problems fast. These steps save time and often fix the issue without extra tools.
Check Volume And Mute Settings
First, check if the volume is low or muted. Sometimes, the audio is on mute by mistake. Use the volume knob or buttons to increase sound. Look for a mute icon on the screen. Make sure your settings are correct.
Inspect External Devices
Look at any devices connected to your Subaru’s audio system. Loose cables or bad connections can stop sound. Check USB drives, phones, or Bluetooth devices. Disconnect and reconnect them. Try playing audio from different sources to test.
Restart The Infotainment System
Restarting the system often solves glitches. Turn off the car and open the door. Wait a few minutes before restarting the engine. Some models allow a reset button on the system. Follow your manual to reset the infotainment system safely.
Resetting The Audio System
Resetting the audio system can often fix many common issues in your Subaru. It helps clear minor glitches that stop sound from working properly. This process is simple and does not require special tools. You can try a soft reset first, which is quick and easy. If that does not help, a factory reset may be needed. Both methods restore the system’s normal function in different ways.
Soft Reset Methods
A soft reset restarts the audio system without erasing your settings. Start by turning off your car and opening the driver’s door. Wait for about one minute to let the system fully power down. Close the door and turn the car back on. This often clears small bugs.
Another way is to press and hold the power button on the audio system for 10 seconds. The screen will go dark and then turn back on. This method refreshes the system while keeping your saved preferences intact. Soft resets are safe and quick fixes to try first.
Factory Reset Options
A factory reset restores the audio system to its original settings. This means all your saved data, like radio presets and Bluetooth connections, will be erased. Use this step only if the soft reset does not solve the problem.
To perform a factory reset, find the settings menu on your Subaru’s display. Look for “System” or “Audio Settings” and select “Factory Reset” or “Restore Defaults.” Confirm your choice. The system will reboot and clear all custom settings.
After the reset, you need to set up your audio preferences again. This method often fixes deeper system errors that a soft reset cannot. Use it carefully, as it wipes all personal data.

Inspecting Hardware Components
Checking the hardware parts is key to fixing Subaru audio problems. Hardware issues often cause sound failures. A careful look at speakers, head units, and antennas helps find the problem fast. This section guides you through basic hardware checks. It uses simple steps to spot common faults.
Speaker Condition
Speakers often face wear and tear. Check them for visible damage or dirt. Press gently on the cone. It should move smoothly without noise. Broken speakers might buzz or stay silent. Swap with a known working speaker to test. Loose wires can stop sound. Tighten any loose connections carefully.
Head Unit Examination
The head unit controls all audio functions. Make sure it powers on properly. Buttons and screen should respond well. Look for blown fuses inside the unit. Resetting the head unit sometimes helps. Check wiring behind the unit for loose plugs. Faulty wiring can cut off sound completely.
Antenna And Receiver Check
The antenna sends signals to the receiver. A broken antenna means no radio sound. Inspect the antenna for bends or breaks. Ensure it is tightly connected to the receiver. Test the receiver by switching radio stations. Static or no signal shows antenna or receiver issues. Replace faulty parts to restore clear sound.
Updating Audio System Software
Updating your Subaru audio system software can fix many sound problems. It helps improve system performance and adds new features. Regular updates keep your system running smoothly and prevent bugs.
Software updates are easy to do at home. You need a USB drive and a computer with internet access. Subaru provides the latest firmware on their official website for download.
Downloading Firmware Updates
Visit Subaru’s official support page for audio updates. Select your car model and year. Download the latest firmware file to your computer.
Use a USB drive formatted to FAT32. Copy the firmware file to the root folder of the USB drive. Make sure the file is not inside any folder.
Installation Process
Turn on your Subaru and insert the USB drive into the USB port. The system will detect the update file automatically. Follow the on-screen instructions to start installation.
Do not turn off the engine or remove the USB drive during update. The process takes several minutes. After finishing, the system will restart.
Check if the audio issues are fixed and the system works well. Repeat the update process if necessary for new firmware versions.
When To Seek Professional Help
Knowing when to get professional help for your Subaru audio is important. Some problems need expert tools and skills. Trying to fix complex issues alone might cause more damage. Recognizing these signs saves time and money. It also ensures your audio system works well again.
Below are clear signs that show it is time to see a professional.
Persistent Audio Failures
Audio problems that keep coming back need expert care. Simple fixes may not work if the problem stays. Professionals can find hidden issues causing the failure. They use special tools to test and diagnose properly. Persistent failures often mean deeper problems inside the system.
Complex Wiring Issues
Wiring problems can be tricky and unsafe. Faulty wires may cause short circuits or no sound at all. Professionals know how to handle Subaru wiring safely. They trace wires and fix connections without harm. Complex wiring fixes need experience to avoid bigger electrical issues.
Hardware Replacement
Some audio parts wear out or break over time. Replacing these parts requires skill and the right tools. Professionals can install new hardware correctly and test it. This ensures the audio system works as it should. Hardware replacement is best done by someone trained and certified.
Preventive Measures For Audio Reliability
Keeping your Subaru audio system working well takes some care. Simple steps help avoid common problems. These steps keep sound clear and the system reliable. Follow these easy tips for better audio performance and fewer issues.
Regular System Maintenance
Check your audio system often for any issues. Clean the screen and buttons with a soft cloth. Update the system software when updates are available. This helps fix bugs and improve features. Inspect cables and connections to ensure they are tight. Loose wires can cause sound problems or interruptions.
Safe Use Of External Devices
Connect phones and music players carefully. Use only cables made for your Subaru model. Avoid forcing plugs into ports. Remove devices gently to stop damage. Turn off the audio system before plugging or unplugging devices. This protects the system from sudden electrical spikes.
Avoiding Moisture Damage
Keep liquids away from the audio system. Avoid using wet hands when touching the controls. Do not leave drinks near the dashboard. Moisture can cause short circuits and corrosion. If the system gets wet, dry it quickly and check for damage. This prevents long-term problems with sound quality.
