The Plymouth Voyager rear location accommodates a 6x9 inch speaker size across all listed model years. Full-range units represent the compatible audio system type for the rear installation. These specifications cover the years 1984 to 1995.
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 speaker location in the Plymouth Voyager accommodates a 6x9 inch oval form factor across all listed model years from 1984 through 1995.
The 6x9 inch oval shape is a non-circular format, meaning the mounting cutout and baffle in the Plymouth Voyager rear position are dimensioned to an elongated oval rather than a round opening.
The larger surface area of a 6x9 inch driver, compared to smaller round formats, increases cone excursion capacity, which allows the driver to move more air and reproduce lower frequencies at the rear of the cabin.
Rear speaker placements in passenger vans such as the Voyager are typically positioned in the rear side panels or rear quarter areas, situating the drivers at a distance from front-seat passengers and directing sound rearward into the passenger compartment.
At the rear of a van-style cabin, the enclosed volume behind the speaker baffle and the surrounding interior surfaces affect low-frequency resonance, making the extended low-end capability of a 6x9 inch driver acoustically relevant to that specific location.
Full-range is the sole compatible speaker type listed for the Plymouth Voyager rear location across all specified model years, indicating a single-driver design intended to reproduce the full audible frequency spectrum from one unit.
A full-range driver integrates low-, mid-, and high-frequency reproduction into a single cone assembly, sometimes with a secondary whizzer cone attached to the main cone to assist with treble dispersion.
In a rear cabin location, a full-range driver handles all frequency reproduction without requiring a crossover network or additional component drivers, as the single unit manages the entire audible range independently.
The 6x9 inch format combined with full-range type designation means the driver in the Plymouth Voyager rear position is expected to handle bass, midrange, and treble frequencies without supplemental woofers or tweeters at that location.
The rear placement of full-range 6x9 inch speakers in the Voyager cabin positions the high-frequency output of the driver at a distance from the primary listening area, since full-range high-frequency dispersion from a large cone is generally narrower than that of a dedicated tweeter.
