The Lincoln Continental rear door panel accommodates a 6x8 inch speaker size. Full-range units are the compatible type for the audio system in this location. These specifications cover the years 1995 to 2002.
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 location places speakers within the lower portion of the cabin side walls, a position that affects both the spatial origin of sound relative to seated occupants and the acoustic coupling between the speaker and the door cavity acting as an enclosure.
Door panel mounting typically involves a sealed or semi-sealed air volume behind the speaker cone, formed by the door's inner cavity, which influences bass extension and overall low-frequency output behavior.
The 6x8 inch oval format provides a larger radiating surface area than a standard round 6.5 inch driver, which increases cone displacement and supports greater low-frequency output from a door panel location where cabinet volume is constrained.
The elongated oval geometry of a 6x8 inch driver allows the speaker to fit mounting locations that are wider than they are tall, a dimensional characteristic common in door panel cutouts on full-size sedans.
The Lincoln Continental rear door panel accepts only full-range drivers across the entire 1995 through 2002 model range, meaning a single driver at each rear door location is responsible for reproducing the complete audible frequency spectrum assigned to that channel.
Full-range drivers are designed to reproduce low, mid, and high frequencies from a single cone assembly, typically using a whizzer cone or treated surround to extend high-frequency response beyond what the main cone alone would produce.
In a rear door panel position, a full-range 6x8 inch driver handles low-midrange and midbass frequencies with relatively high efficiency due to the cone area, while upper-midrange and treble reproduction depend on the specific driver's high-frequency extension characteristics.
The rear door panel location places the speaker below the primary listening axis of seated passengers, which affects high-frequency directionality since treble wavelengths are short enough to exhibit strong directional behavior and may not project directly toward the listener's ears from a lower door mounting point.
The door panel's structural material and any internal bracing or sound deadening within the door cavity influence resonance and coloration of frequencies reproduced by a 6x8 inch full-range driver mounted at that location.
