Description
SMS Precision 2018–2023 Tesla Model 3 Rear Door Speaker Adapter Pair
Sale unit: Sold as one matched pair — two rear-door speaker adapters.
The 2018–2023 Tesla Model 3 rear doors use a vehicle-specific speaker mounting interface. These SMS Precision adapters retain the Tesla-side geometry and provide a proper mounting surface for the selected aftermarket speaker instead of locking the product to one original source speaker model.
Each pair is made to order in-house from ASA for automotive use. The vehicle-side geometry stays fixed; the speaker opening is produced to the selected or verified cutout used for the order.
Fitment
- 2018–2023 Tesla Model 3
- Rear-door speaker locations
- Built to the ordered speaker cutout
Model Y is not included in this listing. Some source data suggests early Model Y compatibility, but SMS does not carry that claim into this product until the vehicle-side fitment is independently verified.
What Is Included
- Two rear-door speaker adapters
- 3D-printed ASA construction
- Made-to-order SMS Precision production
Adapters only. Speakers, wiring, fasteners, gasket material, foam, and sound treatment are not included.
Check the Speaker Before You Order
When the exact speaker model is available in the SMS fitment database, the opening can be produced from its verified published cutout. If the exact model is not listed, provide the required cutout measurement.
Mounting-depth responsibility: matching the adapter opening does not guarantee clearance inside the vehicle. The buyer is responsible for confirming basket, magnet, terminal, window/regulator, door-metal, grille, and interior-panel clearance.
This is a vehicle-specific, made-to-order SMS Precision product. Orders cannot be canceled or refunded after production begins, except where applicable law requires otherwise.
