No computer? Do it all on your phone

Your Tesla only reads these files from a USB drive — there’s no way to send them over Bluetooth or Wi-Fi. But you don’t need a computer: a phone and a USB-C flash drive are enough.

  1. Get a USB-C flash driveMost new phones (and iPhone 15 or newer) have USB-C. Older iPhones need a Lightning-to-USB adapter. Drives usually come formatted exFAT or FAT32, which the car reads; phones can’t reformat a drive, so avoid NTFS.
  2. Make and download the file hereiPhone saves downloads to Files → Downloads. Android saves to the Downloads folder.
  3. Plug the drive into your phoneiPhone: open Files → Browse, and the drive appears under Locations. Android: open Files (or your file manager) and pick USB storage.
  4. Put the file in the right placeOn the drive, create a folder named Boombox (iPhone: long-press empty space → New Folder) and move your sounds into it — up to five.
  5. Unplug and take it to the carPlug the drive into the car’s USB port and wait a few seconds.

How to add custom Boombox sounds

  1. Make your soundsPick from our free original sounds or trim your own audio below, give each one a name, and download it as a WAV.
  2. Create a Boombox folderOn a USB drive formatted as exFAT or FAT32 (MS-DOS FAT on Mac), create a folder named Boombox at the top level.
  3. Copy up to five soundsPut your .wav or .mp3 files inside the Boombox folder. Tesla’s manual allows up to five custom sounds.
  4. Plug in and pick a soundInsert the drive, open Toybox → Boombox and choose your sounds from the USB section.
  5. Play while parkedBoombox plays through the external pedestrian warning speaker. Custom sounds only play while the car is parked.

Sounds not showing up?

  • Folder name: exactly Boombox, at the top level of the drive.
  • File type: .wav or .mp3. Watch for hidden double extensions like horn.wav.wav on Windows.
  • Drive format: exFAT or FAT32 — NTFS isn’t supported.
  • Too many files: keep it to five or fewer.
  • Car in Park: Boombox won’t play while driving.

Boombox details change between software versions. We are testing these steps on a Model Y and will mark what we’ve confirmed.

Questions

Which Teslas have Boombox?

Cars with the external pedestrian warning speaker, which started appearing around September 2019 and varies by model, year and region. If your car hums at low speed, it has the speaker.

Can I use Boombox while driving?

No. After a 2022 software recall in the US, Boombox sounds only play in Park. Custom horn sounds also only replace the horn while parked; the normal horn is used when driving.

How many custom Boombox sounds can I have?

Tesla’s manual says up to five, placed in a top-level folder named Boombox on the USB drive.

Is there a file size limit?

Tesla doesn’t publish one. Short files load most reliably; our tool caps clips at 10 seconds, which keeps each WAV under 1 MB.

Is Boombox different from the lock sound?

Yes. The lock sound is one file named LockChime.wav at the top level of the drive. Boombox sounds go in the Boombox folder. Both play through the same external speaker. Use our lock sound maker for LockChime.wav.
