Speaker mounting rings for Smart cars are used for precise, stable and professional installation of new speakers in factory mounting positions without the need to intervene in the body or interior.

All washers are designed with the specifics of Smart cars in mind and enable quick and safe replacement of speakers without the need for modifications to the door panels. Rings of various depths and diameters are available - most often 130 mm, 165 mm or 200 mm - for use in front and rear doors.
