This is a front door speaker spacer designed for the new (2019/2020) Jimny. This spacer allows you to mount larger (13 cm / 5.25 inch) speakers. One file (Rev A) fits the passenger door, it doesn't have a cutout for the speaker terminals, but the speaker still fits. The second file (Rev C) is rotated so that the Pioneer speakers sit with the labels horizontally. Rev C has a recess for the speaker terminals. It is recommended to use two Rev C designs and ignore the angle of the speaker. Mounted to the door frame using weatherstrip type adhesive foam. It is recommended to use Pioneer TS-G1320F speakers (5.25 inches).
