Tesla Boombox: how it works, which cars have it and how to add custom sounds

Boombox lets your Tesla play sounds out loud through its external speaker, the one built for the Pedestrian Warning System. It works when the car is in Park, it lives in Toybox > Boombox, and you can load your own sounds from a USB drive: make a folder called Boombox at the top of the drive, add WAV or MP3 files, plug it into a front USB port and pick a sound from the Boombox menu.

That is the short version. The details below save you a few trips to the car.

Which Teslas have Boombox

Boombox needs the Pedestrian Warning System (PWS) speaker, the small external speaker that makes the low-speed hum pedestrians hear. Tesla's owner's manual puts it plainly: Boombox is only available on vehicles equipped with PWS. Most Model 3 and Model Y cars built from late 2019 on have the speaker, as do newer Model S, Model X and Cybertruck.

The quickest check: open Toybox on the touchscreen. If you see Boombox, your car has the speaker.

Using the built-in sounds

1. Put the car in Park.
2. Open Toybox > Boombox.
3. Pick a sound and tap to play it through the external speaker.

Boombox plays only in Park. That is a safety rule, so the external speaker is never used for anything but the pedestrian warning while the car is moving.

Adding your own Boombox sounds

Tesla's manual lays out the requirements, and they are strict about a few things:

1. Format the USB drive as exFAT, MS-DOS FAT, ext3 or ext4. NTFS does not work.
2. Create a folder named Boombox at the top level of the drive.
3. Add your sounds as .wav or .mp3 files inside that folder.
4. Name files simply. Stick to letters, numbers, dashes and underscores, with no spaces: door-chime.wav works where door chime.wav may not.
5. Plug the drive into a front USB port and choose your sound from the Boombox dropdown.

Two limits catch people out:

• Only the first five files count. You can store more, but the car offers the first five in alphabetical order. Prefix your favorites with 1-, 2- and so on to control the order.
• Give Boombox its own drive. Tesla's manual describes a Boombox drive that holds just the Boombox folder, so the simplest setup is a separate stick for Dashcam and Sentry recordings.

Where to get good Boombox sounds

Short, clean sounds work best: two to five seconds, no long silence at the start. The FrunkLab lock sound library has nearly 400 free sounds that are already clean WAV files under five seconds, which makes them a good fit for Boombox too. Filter by category, play them in the browser, and download the ones you like.

Want something nobody else has? The AI lock chime generator turns a short description into a sound file. Melody and voice sounds are free every day.

Boombox versus a custom lock chime

They are two different features that both use your USB drive:

Troubleshooting

• Boombox does not appear in Toybox. The car likely has no PWS speaker.
• Your sounds do not show up. Check the folder name is exactly Boombox, the files are WAV or MP3 with no spaces in their names, and the drive is not NTFS.
• Only some sounds appear. Only the first five files, alphabetically, are offered.
• Nothing plays. Confirm the car is in Park.

Frequently asked questions

Does every Tesla have Boombox? No. It needs the external Pedestrian Warning System speaker. If Boombox shows in Toybox, your car has it.

Can I use Boombox while driving? No. Boombox plays only when the car is in Park.

How many custom Boombox sounds can I add? As many as fit on the drive, but the car only offers the first five files in alphabetical order.

What file types does Boombox accept? WAV and MP3 files, in a folder named Boombox at the top of the USB drive.

Can I use a Boombox sound as my lock chime? A custom lock chime is set separately: a single file named LockChime.wav at the top of the drive, chosen in Controls > Locks.
