These adapters are designed for the front door speakers of the BMW E46. They include mounts for the tweeter and woofer.

The mounts are designed for the JL Audio C3-525 component kit, but generic .stp files are included to customize the design for your speakers.

Woofers are screwed into printed adapter rings and then secured to the door card using factory mounting screws.
Tweeters are pivoted and held in place by built-in springs.
Tweeter mounts also utilize factory screws to secure them to the door cards.

Left and right adapters are exactly the same, there is no need to mirror the mounts. They fit perfectly without any issues during installation.
