Chrysler PT Cruiser Rear Speaker Size
The Chrysler PT Cruiser rear location accommodates a 6.5 inch speaker size and 6x8 inch speakers across the model's production span. Compatible types include full-range and midbass audio system units. These specifications cover the 2001 to 2005 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2005 | Midbass / Full-Range | 6.5 |
| 2004 | Full-Range | 6x8 |
| 2003 | Full-Range | 6x8 |
| 2002 | Full-Range | 6x8 |
| 2001 | Full-Range | 6x8 |
Speaker Types
| Type | Description |
|---|---|
| Midbass | A driver tuned for upper bass and lower midrange, roughly from 80 Hz to 500 Hz. It has longer cone travel than a full-range unit, which supports stronger bass in doors and panels. |
| Full-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 Chrysler PT Cruiser accommodates 2 distinct speaker sizes across the model years listed: 6.5 inch (round) and 6x8 inch (oval).
- The 6x8 inch oval format is a non-circular mounting footprint, meaning the mounting aperture and baffle cutout dimensions differ from standard round speaker openings, and physical fitment requires a speaker built to that oval profile.
- A 6.5 inch round speaker, as fitted in the 2005 Chrysler PT Cruiser rear location, occupies a smaller overall mounting diameter than the 6x8 inch oval, indicating the rear enclosure or panel opening was revised between model years.
- The 6x8 inch format produces a larger cone surface area than a 6.5 inch round driver, which generally allows greater air displacement at lower frequencies from the same rear mounting position.
- Full-range speakers, the only compatible type listed for the 6x8 inch rear position, are single-driver units designed to reproduce the entire audible frequency spectrum from one cone, covering bass, midrange, and high-frequency content from a single mounting point.
- The rear location of a vehicle is typically spatially separated from the listener, meaning full-range drivers placed there contribute ambient and spatial sound reinforcement across all frequency bands rather than localized or directional audio.
- The 2005 rear position additionally accepts midbass drivers, which are optimized for frequencies roughly between 80 Hz and 500 Hz, emphasizing lower midrange and upper bass reproduction rather than the full spectrum.
- A midbass driver in the rear location operates within a band where wavelengths are long enough to be largely omnidirectional, making rear placement acoustically practical for that frequency role.
- The cone area of a 6.5 inch round driver is approximately 33 square inches, while a 6x8 inch oval driver covers approximately 38 square inches, reflecting a measurable difference in radiating surface between the 2 rear configurations.
- Oval speakers such as the 6x8 inch format are commonly used in automotive installations where vertical depth in the door or rear panel is limited, as the shorter axis of the oval reduces the required cutout height compared to a larger round driver of equivalent area.
