Also, two types of front sash trim, a resin type <vehi-
cles with 6 speakers> and punching metal type 
<vehicles with 9 speaker 7 position system>, are 
available. With the punching metal type, the metal is 
adopted for the punching part to enlarge the punch-
ing opening, enabling the playback of cleaner treble.

Door speaker box

NOTE: The parts with "*" are installed exclusively to the vehicles with 9 speaker 7 position system (Rockford 
Fosgate premium sound system).
For vehicles with 9-speaker 7-position system, the 
door opening of the vehicle has been blocked by the 
door speaker bracket (front: sheet metal cover, rear: 
resin cover), door speaker cover (resin cover), and 
acoustic material of door water proof film to make the 
door into a speaker box, thus improving the sound 
quality. As an advantage of the door speaker bracket 

(sheet metal cover), the rigidity of the areas around 
the speaker has been increased, and the higher 
sound pressure, suppression of high harmonic, and 
suppression of dumping are achieved to improve 
sound quality.

.

Serviceability

The one-touch installable speaker (with 3 tabs, fixed 
by rotating) has been adopted to improve service-
ability.
