Jeep Compass Rear Door Panel Speaker Size
The Jeep Compass rear door panel accommodates a 6x9 inch speaker size, and also supports 6.5 inch, 6x8 inch, and 3.5 inch speakers. Compatible audio types across these sizes include full-range, midbass, and midrange units. These specifications cover the 2007 to 2017 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2017 | Full-Range | 6x9 |
| 2017 | Midbass / Full-Range | 6.5 |
| 2016 | Full-Range | 6x9 |
| 2015 | Midrange | 3.5 |
| 2015 | Full-Range | 6x8 |
| 2015 | Full-Range | 6x9 |
| 2014 | Full-Range | 6x9 |
| 2013 | Full-Range | 6x9 |
| 2012 | Full-Range | 6x9 |
| 2011 | Full-Range | 6x9 |
| 2010 | Full-Range | 6x9 |
| 2009 | Full-Range | 6x9 |
| 2008 | Full-Range | 6x9 |
| 2007 | Full-Range | 6x9 |
Speaker Types
| Type | Description |
|---|---|
| Midrange | A driver for the middle of the audible range, typically from about 300 Hz to 5,000 Hz, where vocals and most instruments sit. It is often paired with a tweeter and a woofer. |
| 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 door panel of the Jeep Compass is an in-door mounting location, meaning speakers are installed within the door cavity and radiate sound into the cabin from a low lateral position relative to seated passengers.
- Door panel mounting places speakers in an enclosed cavity with limited depth, which constrains the maximum driver excursion and enclosure volume available to any installed speaker.
- The 6x9 inch oval format appears across the widest range of model years in the rear door panel position. The elongated oval geometry increases cone surface area compared to a round driver of similar mounting diameter, which supports greater low-frequency displacement within the spatial constraints of a door cavity.
- Full-range speakers, which are the only compatible type listed for the 6x9 inch size, are designed to reproduce a broad frequency spectrum from a single driver, covering bass, midrange, and treble within one unit.
- The 6x8 inch size listed for 2015 is also an oval format and shares the acoustic principle of expanded cone area relative to equivalent round drivers, making full-range reproduction in the rear door position feasible from a single driver.
- The 6.5 inch round format listed for the 2017 Jeep Compass rear door panel is compatible with both midbass and full-range types. A round 6.5 inch driver provides a smaller cone area than the 6x9 oval, which shifts its acoustic emphasis toward midrange and upper bass frequencies.
- Midbass, one of the compatible types for the 6.5 inch size, is a speaker category focused specifically on the frequency band between bass and midrange, roughly 80 Hz to 500 Hz, without a separate tweeter element.
- The 3.5 inch size listed for 2015 is the smallest diameter in the specifications. At the rear door panel location, a 3.5 inch driver has limited cone area and reduced ability to move air at low frequencies, making midrange the acoustically appropriate role.
- Midrange, the only compatible type listed for the 3.5 inch size, covers the frequency band most associated with vocal and instrumental presence, typically 500 Hz to 5 kHz, and relies on other drivers in a multi-speaker system to handle bass reproduction.
- The presence of a 3.5 inch midrange alongside a 6x8 inch and a 6x9 inch full-range entry within the same 2015 model year indicates the rear door panel accommodated multiple distinct speaker configurations depending on trim or factory audio system variant.
- Rear door panel locations in vehicles typically direct speaker output toward the lower body of rear-seat passengers, which affects the perceived spatial distribution of sound compared to dash or pillar-mounted positions at ear level.
- The physical dimensions of oval formats such as 6x8 and 6x9 require a mounting cutout shaped to match the specific aspect ratio of each size, meaning the two oval formats are not interchangeable despite their acoustic similarities.
