Description
SMS Precision 2015–2024 Infiniti Q50 Rear Door Speaker Adapter Pair
Sale unit: Sold as one matched pair — two rear-door speaker adapters.
The 2015–2024 Infiniti Q50 rear doors use a Nissan/Infiniti-specific speaker mounting interface. These SMS Precision adapters retain the verified Q50-side mounting geometry and provide a made-to-order opening for the selected aftermarket speaker.
Each pair is produced in-house from ASA for automotive use. The vehicle-side mount remains fixed; the speaker opening is generated to the verified or customer-provided cutout.
