The Chrysler 300M rear location accommodates a 6x9 inch speaker size across all listed model years. Compatible types for the rear position include full-range units. These specifications cover a range of years from 2001 to 2003.
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 Chrysler 300M accommodates 6x9 inch drivers across the 2001, 2002, and 2003 model years.
A 6x9 inch speaker occupies a notably elongated oval footprint, which requires a mounting cavity with sufficient depth and clearance behind the cone to prevent physical contact with structural elements during excursion.
The 6x9 inch format produces a larger cone surface area than round mid-range alternatives, which increases low-frequency displacement capability within the rear deck or door panel where air volume is limited.
Rear deck installations, typical of sedans in the 300M class, position speakers horizontally and fire upward toward the rear window, a geometry that affects high-frequency dispersion toward front-seat listeners.
The horizontal orientation of a rear deck mount means the speaker's surround and basket must withstand gravitational load perpendicular to the cone axis, placing stress on the suspension components over time.
Full-range is the only compatible type listed for the Chrysler 300M rear location, indicating a single driver is designated to reproduce the entire audible spectrum at that position rather than splitting duties between dedicated low- and high-frequency components.
A full-range driver incorporates a main cone for mid and low frequencies alongside a small whizzer cone or integrated tweeter element to extend response into higher frequencies, allowing a single unit to function across the broadest possible bandwidth.
In a rear deck position, a full-range 6x9 inch driver handles bass frequencies that benefit from the trunk cavity acting as a passive acoustic chamber behind the mounting surface, which can reinforce low-end output.
The 6x9 inch cone area is large enough that upper-frequency reproduction can exhibit directional beaming, meaning high-frequency energy narrows into a focused beam rather than dispersing widely as driver diameter increases relative to wavelength.
