The Dodge Mirada rear location accommodates a 6x9 inch speaker size in the rear position. Compatible types for the audio system include full-range replacement units. These specifications cover the 1980 to 1983 model chart range.
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 Dodge Mirada accommodates a 6x9 inch mounting footprint across all listed model years.
A 6x9 inch oval speaker driver has a larger cone surface area than a standard round 6.5 inch driver, which increases low-frequency displacement and extends bass response in a rear deck or rear panel mounting position.
The elongated oval geometry of a 6x9 inch speaker distributes the cone area across a wider lateral dimension, which suits the typically shallow and wide cutout profiles found in rear decks of late 1970s and early 1980s American sedans and coupes.
The Dodge Mirada rear location, fitted with a 6x9 inch driver, positions the speaker behind the passenger cabin, directing sound forward and upward toward occupants from the rear field.
Full-range is the sole compatible type listed for the Dodge Mirada rear location, meaning the driver is expected to reproduce the entire audible frequency spectrum from a single cone unit, including low, mid, and high frequencies.
A full-range driver at a rear deck location handles bass frequencies that benefit from the structural mass of the rear shelf acting as a baffle, reinforcing low-frequency output through surface area coupling.
Full-range speakers designed for 6x9 inch frames frequently incorporate a small whizzer cone or integrated tweeter element to extend high-frequency reproduction, compensating for the natural rolloff of a large oval cone at upper frequencies.
The rear deck mounting position places the 6x9 inch full-range driver at an elevated angle relative to seated occupants, which affects the dispersion pattern of mid and high frequencies arriving at the listening plane.
