The Chrysler Pacifica tail gate accommodates a 6x9 inch speaker size. Full-range units represent the compatible speaker types for the tail gate audio system. These specifications cover the 2017 model year.
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 tail gate is a rear-mounted, typically flat or lightly contoured panel surface, which positions a speaker at the furthest rearward point of the vehicle's cabin or cargo area.
A tail gate mounting location places the speaker firing inward toward the cabin, meaning the driver and passengers receive sound from behind and below the typical ear level of seated occupants.
The 6x9 inch oval format accommodates a larger cone surface area than a standard round speaker, which increases low-frequency displacement capability within the constraints of a panel-mounted cutout.
The elongated oval geometry of a 6x9 inch driver allows the speaker to fit within structural panel cavities that are too narrow for a comparably sized circular driver.
In a tail gate position, the 6x9 inch size supports extended bass output, which is acoustically significant because low-frequency sound is omnidirectional and reinforces cabin sound pressure from the rear.
A full-range speaker type is designed to reproduce the entire audible frequency spectrum - typically from approximately 50 Hz to 20,000 Hz - within a single driver unit, without relying on passive crossover networks to divide frequencies between separate drivers.
In the tail gate location of the 2017 Chrysler Pacifica, the full-range type means a single driver handles both low-frequency body and high-frequency detail, which is a requirement when the installation position accommodates only 1 driver per side or per panel.
Full-range drivers at a tail gate position contribute to rear-fill sound, where ambient and spatial audio cues are reproduced from behind the listening position to support stereo or surround staging.
The tail gate location is subject to mechanical vibration from the latch mechanism, hinges, and road input, which affects the structural demands on a speaker's basket and mounting hardware at that position.
