You’re driving in your Tesla Model 3, and the subwoofer suddenly stops. Now, you’re sitting in the car, wondering why this problem occurred. Also, what can you do to fix it? We researched and asked different automotive experts about these concerns, and here’s what we found.
The problems potentially causing a Tesla Model 3’s subwoofer to fail often range from a software issue to a complete component failure.
Finding out the cause of the issue should be the first step to fixing the audio system. But you might only need to reset the sound system to restore the subwoofers’ normal functions.
You should keep reading as we talk about the possible reasons why your Tesla Model 3 subwoofer isn’t working in greater detail. We’ll also tackle some potential solutions that may help you solve this problem as you go through this post.
Reasons Why Tesla Model 3’s Subwoofer Stopped Working
An error or glitch in the Tesla Model 3’s operating system could cause the subwoofer to malfunction or fail to work at all. At the time of writing, multiple sources might be the cause of the software fault.
For instance, an update caused the car's audio system to fail at providing low sound frequencies in audio files. Take note that these audio signals usually come from the subwoofer.
Disconnected Or Loose Wires
Like other electronic systems, a Tesla Model 3’s sound framework should operate as a uniform unit run by wires. A disconnected or loose wire connected to the subwoofer can prevent that component from working.
Wrong Equalizer Settings
Tinkering with the Tesla Model 3’s audio equalizer might also be the reason for the subwoofer’s malfunction. You can diagnose if the equalizer settings are at fault by checking it from the car's center display. Then, make sure that the low frequencies are reasonably high, which should allow the subwoofer to produce decent bass.
Perhaps the particular subwoofer on your Tesla Model 3 is defective. On the other hand, frequent use for extended periods might cause the subwoofer to wear out. In particular, car subwoofers usually last about 4 to 10 years. Think about replacing the subwoofers in your vehicle if they’re older than that period.
How Do You Reset A Tesla Model 3 Subwoofer That’s Not Working?
Resetting the Tesla Model 3’s audio system, including its subwoofers, may only need you to disconnect it from the rest of the car overnight. Then, reconnect it when you wake up in the morning. Doing so could restore the subwoofer’s normal functions.
An alternate method you may use includes the following steps:
- Press and hold both audio scroll wheels in the Model 3's center console.
- Maintain sufficient holding pressure even when the main infotainment system to goes black.
- Release the scroll wheels after you see the Tesla logo on the display.
- Turn on the sound system and the subwoofers to check if the problem persists.
How To Replace The Subwoofer In A Tesla Model 3?
It’s important to mention that replacing parts of the Tesla Model 3’s audio system, particularly the subwoofer, doesn’t void the car’s warranty. You may also consult with the vehicle manufacturer’s customer service hotline if you’re unsure about this decision.
Also, ensure that you have sufficient knowledge in working with automotive electronics. Request help from industry experts if you believe you don't have adequate confidence and/or know-how to proceed with this replacement procedure.
If you wish to continue, move forward by following these steps:
What You’ll Need
- Panel remover
- Ratchet and socket set
- Wrench set
- Replacement subwoofer installation kit
Step #1: Park The Vehicle
Drive your Tesla Model 3 into a safe and shaded spot. Make sure that the car is on flat and level ground. Engage its brakes, and chock the wheels to ensure the vehicle doesn’t move while you’re working on it.
Step #2: Remove The Rear Panels
Open the Tesla Model 3’s trunk. Next, remove the panel clips securing the rear speaker setup. Pull out the panel afterward.
Moving forward, remove the rubber gasket by pulling it from its mount. Then, set it aside temporarily. You should be able to expose the lower panel after removing the rubber gasket. Once exposed, pull the lower panel from its mount and set it aside.
Step #3: Remove The Back Seat
Take note that the back seat secures the trunk liner. It should also be the last piece covering the rear subwoofer.
Start this step by flipping a lever from the back seat. Doing so should loosen the seat cushion. Pull up the seat cushion and disconnect the wire attached to it. You should be able to remove the seat cushion and set it aside for now. Don’t forget to remove the cushion from the other back seat as well.
Next, remove the back cushion by tugging it out of its mount. It might be quite challenging to pull it out as clips secure the assembly. You’ll hear an audible snapping sound, signifying the cushion’s release. Pull the cushion up and out of its assembly afterward. Again, repeat this part of the procedure for the other seat.
Remove the rest of the back seat assembly by unscrewing the bolts for each side. Then, disconnect the wire harness from the seat. Pull out the newly exposed panel afterward.
Step #4: Replace The Subwoofer
Remove the remaining covers from the Tesla Model 3’s trunk. Doing so should expose the car’s subwoofer and amplifier assembly.
Disconnect the wires attached to the subwoofer. Then, unscrew it from its wall mount. Gently pull out the old subwoofer afterward. Next, install the new subwoofer according to the manufacturer’s instructions.
At this point, you can test the new subwoofer by turning on the vehicle’s audio system. Play some tracks, especially those with deep bass signatures. If the new unit is working as intended, continue to the next step. Otherwise, troubleshoot the issues you may come across at this time.
Tip: Take a picture of the old subwoofer assembly. That way, you won’t forget the placement of the wires for the new unit.
Step #5: Reinstall The Removed Parts
Return the trunk covers to hide and secure the new subwoofer. Next, reinstall the back seat assembly. Don’t forget to reinstall the rubber gasket, which may need a fresh application of adhesive for it to stick.
Note: Some of the steps mentioned in this procedure may differ depending on your Tesla Model 3 unit. Premium trims often only have to work on the subwoofer from the trunk. On the other hand, Model 3 base models may need to connect the new subwoofer to the front speakers for it to work properly.

What Is The Best Subwoofer For Tesla Model 3?
Bear in mind that one subwoofer can’t provide all benefits to Tesla Model 3 users. However, some subwoofers have quality features, allowing them to outshine their competitors.
Some ideal candidates for your next Tesla Model 3 subwoofer are:
Rockford Fosgate P1S4-12 Punch Subwoofers
With up to 500 watts of audio prowess, these subwoofers can eke out deep bass signatures from different tracks. It comes with a Kevlar-reinforced cone to help deliver deep and heavy low audio signatures.
However, the bass doesn’t muffle other parts of the audio spectrum, allowing the sound-listening experience to maintain its balance and stability.
MTX TN8MS Terminator Amplified Subwoofer
Despite having “amplified” in its name, the MTX TN8MS provides subtle bass performance that won’t rock your Tesla Model 3. However, this unit pronounces the low audio signatures instead of “shouting” them. That way, the product doesn’t drown out the mids and highs of each audio file played.
Kicker 48CWR82 Subwoofer
This subwoofer for Tesla Model 3s promotes a potent low-frequency kick. It comes with a durable polypropylene cone to help maintain stability through powerful bass-listening sessions. Its installation should also be reasonably easy, thanks to the included instruction manual.
A Tesla Model 3’s subwoofer may not work if it encountered a software or hardware issue. Make sure to troubleshoot the audio system to find the source of the failure. You can then apply the appropriate DIY solution based on your findings. If not, request help from trustworthy automotive technicians to do the repair job for you.
