Plymouth Grand Voyager Rear Door Panel Speaker Size
The Plymouth Grand Voyager rear door panel accommodates a 6x9 inch speaker size. Full-range units are the compatible types for the audio system in that location. These specifications cover the years 1990 to 2000.
A single driver that reproduces bass through treble without a separate crossover network. It is the simplest replacement option and is common in factory audio systems.
Additional Notes
The rear door panel speaker location on the Plymouth Grand Voyager accommodates a 6x9 inch driver across all listed model years from 1990 through 2000.
A 6x9 inch speaker is an oval format, and the elongated shape allows a larger cone surface area compared to a round 6.5 inch driver, which increases low-frequency displacement and overall volume output from a door panel cavity.
Door panel locations place speakers at or below seat level, meaning the rear door panel position radiates sound upward and inward toward cabin occupants in the rear seating area of the Grand Voyager.
The oval geometry of a 6x9 inch driver requires a mounting cutout shaped to match the elongated footprint, making the door panel recess on the Plymouth Grand Voyager specific to oval-format speakers of that dimension.
At the rear door panel position, low- and mid-frequency reinforcement is a primary acoustic function, as door panels are physically separated from the front stage and must sustain bass and midrange energy across the rear cabin zone.
Full-range is the sole compatible speaker type listed for the rear door panel location, indicating the mounting space accepts a single driver intended to reproduce the entire audible frequency spectrum rather than a dedicated low- or high-frequency component.
A full-range driver integrates a woofer cone with a passive radiator or whizzer cone to extend high-frequency response, allowing a single unit to cover bass, midrange, and treble frequencies from one mounting point.
In a rear door panel environment, a full-range 6x9 inch driver handles frequencies typically spanning from approximately 50 Hz up to 20 kHz, with the larger cone surface contributing to stronger bass reproduction relative to smaller full-range formats.
The rear door panel mounting depth and baffle structure of the Grand Voyager determine the available airspace behind the speaker cone, which directly influences the low-frequency extension a 6x9 inch full-range driver can produce at that location.
Because full-range drivers at the rear door panel must reproduce the complete frequency spectrum without crossover filtering, the 6x9 inch cone must manage both the mechanical demands of low-frequency excursion and the precision required for midrange and high-frequency detail simultaneously.
