The Chrysler Concorde rear deck lid accommodates a 6x9 inch speaker size in that location. Full-range units represent the compatible audio system type for the replacement. These specifications cover the 1993 to 2004 chart of model years.
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 deck lid of the Chrysler Concorde is the horizontal panel positioned at the back of the passenger cabin, situated beneath the rear window and above the trunk cavity.
In a sedan body style, the rear deck lid placement positions speakers to radiate sound forward into the cabin, with the rear window acting as a reflective surface that can influence how high-frequency content disperses toward front and rear seating positions.
The 6x9 inch oval format is among the largest standard speaker sizes used in automotive installations, and the elongated geometry of the cone allows for a larger surface area compared to a circular equivalent, which supports greater air displacement at lower frequencies.
Greater cone surface area in the 6x9 inch format means the drivers at the Chrysler Concorde rear deck lid location are capable of reproducing bass and lower midrange frequencies with more authority than smaller diameter speakers mounted elsewhere in the vehicle.
The mounting depth and baffle space available in a rear deck lid are generally greater than in door panels or dash locations, which accommodates the deeper basket and magnet assemblies typical of 6x9 inch drivers.
Full-range speakers are designed to reproduce the audible frequency spectrum within a single driver, integrating woofer cone behavior for low frequencies with a whizzer cone or internal tweeter element to extend high-frequency response.
The full-range type is the sole compatible type listed for the Chrysler Concorde rear deck lid across all model years in the specifications, meaning no component or coaxial multi-driver configurations are listed as alternatives for the location.
A full-range driver at the rear deck lid position handles bass, midrange, and treble reproduction simultaneously, which is acoustically relevant because the location is distant from front-seat listeners and the speaker must project across a significant portion of the cabin length.
The 6x9 inch full-range format at the rear deck lid means the low-frequency output originates from a rearward position in the cabin, which can contribute to a sense of spaciousness in the bass frequencies due to the distance from the primary listening position.
Because the rear deck lid is a fixed structural panel rather than a moving component like a door, the mounting surface is relatively rigid, which reduces resonance coupling that could otherwise color the sound produced by the 6x9 inch full-range drivers.
