There’s nothing more frustrating than turning on your favorite playlist or podcast and realizing the front speakers in your Subaru have gone silent.
If your Subaru front speakers stopped working, it’s often due to a blown DCM fuse, faulty wiring harness, or amp issue. Try disconnecting the battery to reset the system and restore sound output.
In this guide, we’ll explore the reasons why Subaru front speakers stop working, how to diagnose the problem yourself, and what professional solutions might cost. Whether you’re a DIY car enthusiast or just trying to avoid a costly service visit, this article will help you bring your car’s sound system back to life.
Understanding Subaru’s Audio System
Subaru’s modern sound systems are designed with multiple components working together: the head unit (radio or infotainment system), an amplifier, and a series of speakers and tweeters positioned around the cabin.
In most models, audio signals travel from the head unit to the amplifier and then to the front and rear speakers through dedicated wiring channels.
Higher trims, such as those equipped with the Harman Kardon system, include additional amplifiers or subwoofers to enhance sound quality.
However, this complexity also means more potential failure points. If a connection breaks or a single module fails, the sound can cut off — sometimes only in the front speakers.
Why the Front Speakers Stop Working
There isn’t one single cause, but rather a few common reasons Subaru owners experience this issue.
1. Balance or Fade Settings Misadjusted
Before diving into the wiring, it’s worth checking your audio settings. The “fade” control adjusts how sound is distributed between the front and rear speakers.
If it’s been accidentally set toward the rear, you might think your front speakers are dead when they’re simply turned off through software.
2. Loose or Damaged Wiring
The wiring running through Subaru’s doors is exposed to movement every time you open and close the door.
Over time, these wires can bend or break inside the harness, leading to signal loss. In several Forester and Crosstrek models, owners have discovered that frayed wires near the door hinge were the culprit.
3. Blown Fuse or Faulty Amplifier
A small fuse often protects the car’s audio circuit. If that fuse blows, power to the amplifier or speaker channels may be interrupted. Similarly, if the amplifier’s internal circuit burns out, the front channels might stop working while the rear ones continue.

4. Head Unit Software Glitch
Many recent Subaru models use touch-screen infotainment systems that run on software. After a battery replacement or update, these systems sometimes experience a glitch that disables part of the audio output. Performing a factory reset can often bring the front speakers back.
5. Missing or Disconnected Modules
In some regions, Subaru models use telematics systems (like Starlink) that route calls and alerts through the front speakers. If the module is unplugged or missing, it can break the sound path for those channels entirely.
Step-by-Step Troubleshooting Guide
If your Subaru’s front speakers suddenly go silent, you can perform several checks before booking a service appointment.
Step 1: Verify Basic Audio Settings
Make sure your balance and fade controls are centered. Test different sources like FM radio, Bluetooth, and USB to rule out a single faulty input.
Step 2: Reset the Infotainment System
Many Subaru owners report success after performing a soft or factory reset. Check your owner’s manual for instructions specific to your model and year. Usually, it involves holding certain buttons on the display for a few seconds.
Step 3: Inspect the Audio Fuse
Look under the dashboard or in the engine bay for the fuse box. There should be one labeled “AUDIO” or “AMP.” Pull it out and inspect it under light. If the metal strip inside is broken, replace it with one of the same rating.
Step 4: Check the Door Wiring
If one or both front speakers are silent, the door harness could be the issue. Open the driver’s side door and gently move the rubber boot where the wiring passes through.
If the sound cuts in or out, you’ve found the problem. Fixing this requires removing the door panel to repair or replace the damaged wire.
Step 5: Test the Speakers Directly
If you have access to a multimeter, disconnect the front speaker wires and test for continuity. If the speakers read zero resistance, they’re blown.
If they show normal resistance (around 4 ohms) but still don’t produce sound, the problem lies further upstream — likely the amplifier or head unit.
Step 6: Consider Amplifier or Head Unit Issues
When both front speakers fail at once and the wiring and fuses look fine, the amplifier or head unit may be at fault. Unfortunately, these parts aren’t easily serviceable without professional tools.

Insights from the Community
Car owners often share real-world experiences that help others diagnose issues faster. On SubaruOutback.org, multiple users reported that their front speakers failed right after a battery change. In several cases, the dealership replaced the head unit, which solved the issue but cost close to $900.
Others found simpler fixes. One Crosstrek owner discovered a disconnected wiring harness under the dashboard after an aftermarket dashcam install. Reconnecting it restored the sound instantly.
These examples highlight the importance of checking basic connections before assuming major component failure.
Professional Repair and Cost Estimates
If DIY fixes don’t solve the problem, it’s time to visit a qualified technician or dealership. Costs vary depending on the root cause and region:
- Fuse or wiring repair: $20–$80 (often done by local garages)
- Door harness replacement: $150–$300
- Head unit replacement: $600–$1,200
- Amplifier replacement: $400–$900
Always ask the technician to run a diagnostic test before replacing parts. A professional scan can identify communication faults or short circuits that may not be visible to the naked eye.
If your Subaru is still under warranty, report the issue immediately. In some markets, audio system failures have been covered under the basic warranty period.
Preventive Maintenance Tips
To minimize the risk of future speaker issues:
- Inspect wiring annually. When washing or detailing your car, check that door rubber boots are intact and wires aren’t pinched.
- Keep moisture out. Water intrusion is one of the most common causes of electrical faults.
- Avoid over-voltage during battery replacements. Always disconnect the negative terminal first.
- Update infotainment software. Subaru periodically releases firmware updates that address known bugs, including sound system glitches.
- Use quality components. If you upgrade speakers or install aftermarket equipment, ensure they meet the correct resistance and power ratings.
These small steps can extend the life of your car’s audio system and save you from future frustration.
When to Seek Professional Help
You should contact a certified Subaru technician if:
- Both front speakers fail suddenly without warning.
- The infotainment system displays errors or restarts on its own.
- Sound cuts in and out even after resetting settings.
- You hear static, distortion, or popping sounds from the front channels.
Technicians have access to factory diagrams and diagnostic software, allowing them to pinpoint issues much faster than trial and error.
