Product Overview
Upgrade your Mazda 3 sound system with this custom-designed front door speaker adapter, perfect for replacing the factory Bose speakers. This adapter replicates the 30mm offset of the OEM mount and provides clearance for aftermarket speakers with larger magnets—like the JBL GT609 (6.5", 52mm deep).
It mounts directly to the factory holes using the original screws. To install your new speakers, just secure them to the adapter using 4x M3 screws and washers (not included).
