The Chrysler PT Cruiser rear door panel accommodates a 5x7 inch speaker size in each location. Full-range units represent the compatible audio system type for the rear door panel. These specifications cover the 2002 to 2010 model 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 door panel location in the Chrysler PT Cruiser positions speakers within the lower portion of the door cavity, where mounting depth and baffle area are constrained by the door's internal structure, including window mechanisms and door hardware.
Door panel speaker locations are subject to low-frequency acoustic loss because the speaker cone faces into the cabin laterally rather than directly toward the listening position, which affects perceived bass response and stereo imaging.
The 5x7 inch oval format occupies a larger surface area than a standard 5.25 inch round speaker, allowing for greater cone excursion and improved low-frequency reproduction within the same mounting footprint depth.
The elongated oval geometry of a 5x7 inch driver distributes acoustic energy across a wider baffle surface, which can reduce resonance buildup in the door panel material surrounding the speaker cutout.
In a rear door panel location, the 5x7 inch size addresses the spatial trade-off between maximizing cone area and fitting within the limited mounting cavity that door structures typically allow.
The Chrysler PT Cruiser rear door panel accepts a 5x7 inch full-range speaker across the 2002 through 2010 model years, establishing a consistent mounting cutout dimension throughout the entire production span covered by the specifications.
Full-range speakers are designed to reproduce the entire audible frequency spectrum-generally 20 Hz to 20,000 Hz-from a single driver, using a main cone for low and midrange frequencies and an integrated tweeter or whizzer cone for high-frequency reproduction.
In a rear door panel application, a full-range driver handles midrange vocal frequencies and upper harmonics without requiring a crossover network or a separate high-frequency driver mounted elsewhere in the door.
The absence of a passive crossover requirement in a full-range installation reduces the number of components housed within the door cavity, which is relevant given the spatial limitations imposed by door panel construction.
The rear door panel location places the speaker behind the rear seat occupants relative to the front listening position, meaning the full-range driver in the rear doors contributes ambient and spatial audio information to the overall cabin soundstage rather than direct frontal projection.
