Pair of 2019 to present Sprinter VS30 cab door Speaker Adapter for 6.5" speaker

To determine the ID that is needed please take a measurement as shown in the photo. Sold as a pair, these adapters are for upgrading the speakers in the the front doors of 2019 VS30 Sprinter vans. The factory door panel and speaker grill is retained for a stealth factory look. This is a crucial step to enjoying better sound quality in your van. The adapters were designed in 3D CAD and they are machined on a CNC router. Material for the adapters is ~1/4 thick ABS. It won't absorb moisture like MDF or wood and holds screws well without splitting.  The holes in the adapter are perfectly located and countersunk to mount over the factory posts and be secured with the original screws. Double sided 3M VHB tape also helps to secure and seal the adapter to the back of the door panel. Locating pocket for OEM speaker must be trimmed from back of door panel. Drill holes in the adapter ring for your speakers and secure them with sheet metal screws. We highly recommend installing 3M Thinsul
