The Chrysler Laser rear door panel accommodates a 5x7 inch speaker size across all listed model years. Full-range units are the compatible audio system types for the rear door panel location. These specifications cover the years 1984 to 1986.
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 positions speakers within the door cavity, where the speaker faces into the passenger cabin and is typically mounted on a flat or contoured panel surface.
Door panel installations are subject to spatial constraints from the door's internal hardware, window mechanisms, and structural bracing, which can affect mounting depth and baffle area.
A 5x7 inch speaker occupies a rectangular footprint, and the oval geometry of that format is designed to fit within door cavities where circular cutouts of equivalent cone area would not physically clear surrounding door components.
The 5x7 inch format produces a larger radiating surface area than a standard 5.25 inch round speaker, which supports stronger low-midrange output from a door panel position without requiring a subwoofer enclosure.
The Chrysler Laser rear door panel, across the 1984 through 1986 model years, accepts only 5x7 inch speakers, establishing a fixed cutout dimension that constrains replacement and upgrade options to that footprint.
Full-range speakers reproduce the entire audible frequency spectrum-typically from approximately 80 Hz to 20 kHz-within a single driver, which suits a door panel location where only 1 driver position is available per door.
In a rear door panel position, full-range drivers handle both midrange vocal frequencies and upper-frequency detail, as the door's distance from front occupants naturally reduces high-frequency projection due to off-axis listening angles.
The 5x7 inch driver size in a door panel mounting position benefits from the door cavity acting as a partial acoustic enclosure, which can reinforce low-frequency output from a full-range driver that might otherwise roll off early in free-air conditions.
Full-range drivers in rear door panels are expected to operate without a dedicated crossover network, meaning the driver cone and tweeter-if a whizzer cone or integrated tweeter is present-handle all frequencies assigned to that channel simultaneously.
