Mazda 3 Speaker Adapter

thingiverse

This is an adapter I made for the front door of my 2013 Mazda 3 with the Bose Sound system. The adapter spaces the speaker 30mm off the door matching how the factory Bose speaker was mounted, the speaker I mounted was a 6.5-inch JBL GT609 which is 52mm deep with a large magnet and it cleared the inner door brace nicely. 4 M3 screws and washers are needed to mount the speaker to the adapter, and it uses the factory screws to mount to the door.
