Description
SMS Precision 2005–2025 Nissan Altima Speaker Adapter Rings
Sale unit: Choose one matched pair for the selected location, or a complete set for the matching year range.
The Nissan Altima uses a common Nissan vehicle-side speaker mounting family across multiple generations, but the rear speaker location changes. These SMS Precision adapters retain the verified Nissan-side mount and are produced with the speaker opening required for the selected aftermarket driver.
Each adapter is made to order in-house from ASA. The vehicle-side geometry stays fixed; the speaker cutout is generated from verified speaker geometry or the cutout supplied with the order.
Verified Applications
- 2005–2025: front doors
- 2005–2006: rear deck
- 2007–2025: rear doors
Choose the exact year/location combination in the selector.
What Is Included
- Selected matched pair, or complete front/rear set
- 3D-printed ASA construction
- Made-to-order speaker opening
Adapters only. Speakers, wiring, fasteners, gasket material, foam and sound treatment are not included.
Built to the Actual Driver
Nominal 6.5-inch or 6.75-inch size does not define the exact cutout. When the selected speaker is in the SMS geometry database, the opening can be produced from its verified published dimensions. Otherwise, provide the required cutout measurement.
Clearance responsibility: buyer/installer must verify basket, magnet, terminal, window/regulator, grille, deck-panel and interior-trim 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.
