About this part

These are speaker adapter mounts for BMW E46 front doors. There is a mount for both the tweeter and woofer. The mounts are designed for a JL Audio C3-525 component set but I have included generic .stp files for the mounts to adapt the design for your speakers. The woofers are screwed into the printed adapter rings and then the factory mounting screws are used to fix them to the door card. The tweeters clip into the mount with a twist and are held with integrated springs. The tweeter mounts also re-use the factory screws to hold them to the door cards. Left and right are exactly the same and there is no need to mirror the mounts. These fit perfectly and I have had no issues after a month of i Fuse and insulate any added wiring correctly, secure it from chafe and confirm the circuit remains serviceable.
