Scosche SABW525 brackets will allow you to install select 5-1/4" or 6-1/2" speakers in the factory speaker openings of select 1999-06 BMW 3-Series vehicles. Please enter your vehicle information or call an Advisor at 1-888-955-6000 to confirm that these adapters are compatible with your vehicle. Warranty: 60 days.
Important Note: Some 6-1/2" speakers use a larger frame and require a larger cutout. We call these 6-3/4" speakers, and they won't fit in this bracket. This bracket will only work with speakers that require a cutout diameter of 5-1/8" or less.
