The Chrysler Cordoba rear deck lid accommodates a 6x9 inch speaker size in that location. Full-range units represent the compatible audio system types for that position. These specifications cover the years 1975 to 1983.
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 Cordoba is a horizontal surface positioned at the base of the rear window, above the trunk cavity, and behind the rear seating area.
Mounting at the rear deck lid places speakers in a rearward-facing or upward-angled orientation, directing sound toward the headliner and into the cabin from behind the passengers.
The 6x9 inch oval format is among the larger standard automotive speaker dimensions, with the elongated shape increasing cone surface area beyond what a circular 6-inch driver would produce.
Greater cone surface area in a 6x9 inch driver corresponds to higher air displacement, which supports stronger low-frequency output within an automotive enclosure compared to smaller oval or round formats.
The rear deck lid location on the Chrysler Cordoba places the 6x9 inch drivers at significant distance from the front listening position, which affects perceived stereo imaging and bass reinforcement across the cabin.
A full-range speaker is a single driver designed to reproduce frequencies across the audible spectrum, typically covering bass, midrange, and treble from one cone without a passive crossover network dividing the signal.
Full-range compatibility at the rear deck lid position means a single driver per channel handles the complete frequency output for that location, without requiring a separate tweeter or woofer in the same mounting cutout.
The deck lid surface in a vehicle like the Cordoba is typically a flat, relatively thin panel with a defined cutout pattern, and the structural rigidity of the mounting surface directly affects vibration and resonance behavior at higher output levels.
The 6x9 inch footprint requires a correspondingly sized cutout and sufficient depth clearance beneath the deck panel to accommodate the driver's basket and magnet assembly without contacting the trunk lid mechanism below.
