This is a speaker replacement plan exclusively for Mazda CX-60 BOSE system vehicles.

Door tweeter KST2004
Door speaker KSC3504
Center speaker KSC3504
Dedicated installation kit

This kit allows you to replace the speaker using a dedicated mount and coupler.
The speaker body and cable are connected using a connector on the vehicle side, so you will need to assemble the included connector parts to make the connection.
You will need tools.

Regarding processing on the vehicle side when installing both the door speaker and center speaker -
There is no particular problem with the left and right 2WAY.
When fixing the kicker mount to the genuine center speaker, the genuine mount will be slightly scraped, but it is possible to return it to the original one.
(It's internal so it doesn't change the appearance)
Some adjustment is required.
(Part of the center speaker mount will be cut during installation)
