Description
One pair (two brackets) per quantity ordered. SMS Precision 3D-printed speaker adapters, made to order in black automotive ASA.
2021–2024 Ford Bronco 6G — 4-Inch Speaker Adapters
Vehicle-specific mounting brackets for compatible 4-inch speaker locations in the full-size 2021–2024 Ford Bronco 6G, including supported front dash/corner and rear speaker-pod positions. These brackets adapt the original mounting interface to a compatible aftermarket 4-inch-class speaker. They do not include speakers.
Choose by vehicle, location and speaker dimensions
- Vehicle: Full-size Bronco 6G, 2021–2024. Not Bronco Sport. Confirm year, trim, 2-door/4-door body and factory audio package.
- Location: Factory 4-inch front corner/dash or rear pod position only where the original mounting pattern matches. Factory center speaker, other-size dash locations and 6.5-inch kick-panel speakers use different adapters.
- Speaker: 4-inch class. Check the actual speaker cutout, frame outside diameter, mounting hole spacing, basket/depth, terminals, and grille clearance. The nominal 4-inch designation alone does not guarantee every aftermarket speaker fits.
- Installation: Some speakers require trimming or folding unused speaker mounting ears to clear the vehicle opening. Verify original mounting tabs, fastener access and vehicle trim before installation; a no-trim fit is not guaranteed.
- Build-to-size: Supply your speaker's exact mounting measurements if its basket or screw pattern differs from the listed mounting pattern.
Package
Two matching-size black ASA speaker adapter brackets for the selected 4-inch location; one pair per quantity. For four supported speaker positions, order two pairs. Speakers, harnesses, fasteners, gasket, foam and installation are not included.
CAD envelope: Approximately 145.4 × 107.8 × 8.4 mm. The original vehicle-side mounting pattern and exact speaker dimensions must match the chosen installation.
