The Chrysler LeBaron rear location accommodates a 6x9 inch speaker size. Full-range units represent the compatible audio system replacement type. These specifications cover the years 1977 to 1995.
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 Chrysler LeBaron accommodates a 6x9 inch mounting cutout across all listed model years from 1977 through 1995.
A 6x9 inch speaker is an oval format, meaning the cone surface area is larger than a comparably classified round speaker, which allows for greater air displacement within the rear deck cavity.
The rear deck position in a sedan or coupe body style typically places speakers facing upward toward the rear window, creating a reflective acoustic path into the cabin rather than a direct one.
The 6x9 inch format at the rear deck is associated with extended low-frequency reproduction, as the larger cone diameter supports longer wavelength sound waves more effectively than smaller rear-mounted drivers.
The mounting depth available in a rear deck panel must accommodate the basket depth and magnet assembly of a 6x9 inch driver, which tends to be more substantial than smaller format speakers due to the increased motor and cone structure.
Full-range is the sole compatible speaker type specified for the Chrysler LeBaron rear location, designating a single driver design intended to reproduce the full audible frequency spectrum - typically spanning from approximately 50 Hz to 20,000 Hz - without a dedicated crossover network dividing the signal.
A full-range driver placed in the rear deck of the Chrysler LeBaron operates without the acoustic support of an enclosure, relying on the interior volume beneath the deck as an informal rear chamber, which influences bass response and cone excursion behavior.
The 6x9 inch cone area, combined with a full-range driver design, positions the rear speakers to handle both midrange vocals and lower bass frequencies simultaneously, which is characteristic of installations without a separate subwoofer or tweeter in the same zone.
Rear deck installations generally exhibit a degree of acoustic coupling with the trunk volume below, and in the LeBaron, the 6x9 inch full-range driver may be subject to resonance effects introduced by that shared air space.
Because full-range drivers are not band-limited by a passive crossover, the entire amplified signal - including high frequencies - reaches the 6x9 inch cone, which can introduce beaming or dispersion irregularities at upper frequencies given the relatively large cone diameter.
