FAQ
Which Model S years support custom lock sounds?
The 2021+ Model S refresh has full Boombox support with enhanced external speakers out of the box. Model S from 2016–2020 can also support custom sounds with software version 2020.48 or later, provided external pedestrian warning speakers are installed. Pre-2016 Model S vehicles generally lack the external speaker hardware needed.
Does the Model S dual-speaker system make custom sounds louder?
The dual external speakers give the Model S fuller sound reproduction rather than just more volume. The benefit is richer audio with more depth — complex sounds with harmonics or subtle details come through much better than on single-speaker models. Stereo-encoded WAV files can take advantage of this setup.
What volume level should I target for Model S custom lock sounds?
Normalize to -3dB to -6dB peak. The Model S speakers handle this range cleanly. Unlike the Cybertruck, you don't want to push too hot — the premium speakers are accurate enough that distortion is noticeable. Start at -6dB and increase only if the sound is inaudible at 30 feet.
Why does my older Model S say "Custom Sound Not Available"?
This usually means the software version is below 2020.48, Boombox isn't available in your region, or external speakers weren't installed on your unit. Check Controls → Software for your version. If you're on current firmware and still see this message, contact Tesla Service to verify your external speaker hardware status.
Can I use bass-heavy sounds on the Model S?
Yes — the Model S handles low frequencies better than most other Tesla models. Sounds with cinematic bass, deep synths, or complex orchestral content will reproduce noticeably better than on Model 3 or Model Y. Keep sub-bass frequencies above 100Hz to avoid muddiness on the external speaker path.
