Mercedes-Benz C63 AMG Rear Door Panel Speaker Size
The Mercedes-Benz C63 AMG rear door panel accommodates a 6.5 inch speaker size and supports 1 inch units across the model's production range. Compatible audio types include midbass, full-range, and tweeter units. These specifications cover the 2008 to 2017 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2017 | Midbass / Full-Range | 6.5 |
| 2015 | Midbass / Full-Range | 6.5 |
| 2014 | Midbass / Full-Range | 6.5 |
| 2013 | Midbass / Full-Range | 6.5 |
| 2012 | Midbass / Full-Range | 6.5 |
| 2011 | Tweeter | 1 |
| 2011 | Midbass / Full-Range | 6.5 |
| 2010 | Tweeter | 1 |
| 2010 | Midbass / Full-Range | 6.5 |
| 2009 | Tweeter | 1 |
| 2009 | Midbass / Full-Range | 6.5 |
| 2008 | Tweeter | 1 |
| 2008 | Midbass / Full-Range | 6.5 |
Speaker Types
| Type | Description |
|---|---|
| Tweeter | A small driver built for high frequencies, typically from about 2,000 Hz to 20,000 Hz. It adds treble detail and clarity and is usually mounted near ear level or aimed at the listener. |
| 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 location places speakers within the lower portion of the door cavity, a position that affects both sound projection angle and the distance from the listening ear relative to front-mounted sources.
- Door panel installations are subject to mechanical constraints from the door's internal structure, including window mechanisms and vapor barriers, which influence the available mounting depth and baffle rigidity behind the speaker cone.
- The 6.5 inch diameter is the sole speaker size across all listed model years for the Mercedes-Benz C63 AMG rear door panel, making it the standard cutout dimension for the rear door panel location throughout the entire specification range.
- A 6.5 inch driver in a rear door panel position has sufficient cone surface area to move the air volume necessary for reproducing bass and lower midrange frequencies, which is acoustically appropriate for a location that typically lacks a rigid sealed enclosure.
- Midbass drivers in the rear door panel handle the frequency range roughly between 80 Hz and 500 Hz, reinforcing the lower-midrange and upper-bass content that a door cavity can sustain given its partially open, resonant interior volume.
- Full-range drivers operating in the same 6.5 inch cutout extend the frequency reproduction beyond the midbass range, covering midrange and partial high-frequency content from a single driver without requiring an additional tweeter at the same location.
- The 1 inch tweeter is listed only for the 2008 through 2011 model years alongside the 6.5 inch driver, indicating the rear door panel in those years accommodated a second, separate mounting point for a high-frequency driver.
- A 1 inch tweeter dome operates in the high-frequency range, typically from around 2 kHz upward, where short wavelengths require a small radiating surface to maintain controlled directivity and avoid beaming artifacts.
- Positioning a 1 inch tweeter within the rear door panel places the high-frequency source at a relatively low height and oblique angle toward rear-seat occupants, which influences stereo imaging and treble dispersion within the cabin.
- The pairing of a 6.5 inch midbass driver and a 1 inch tweeter within the same rear door panel, as listed for the Mercedes-Benz C63 AMG in 2008 through 2011, constitutes a 2-way component configuration at the rear door location.
- From 2012 onward, the specifications list only the 6.5 inch position without a corresponding 1 inch tweeter mount, indicating the rear door panel layout carried a single speaker opening during those years.
