GMC Savana Rear Speaker Size
The GMC Savana rear location accommodates a 6.5 inch speaker size and 4x6 inch speakers across the covered model years. Compatible speaker types for these units include midbass and full-range configurations. These specifications cover the years 2000 and 2008 through 2014.
| Year | Type | Size (inch) |
|---|---|---|
| 2014 | Midbass / Full-Range | 6.5 |
| 2013 | Midbass / Full-Range | 6.5 |
| 2012 | Midbass / Full-Range | 6.5 |
| 2011 | Midbass / Full-Range | 6.5 |
| 2010 | Midbass / Full-Range | 6.5 |
| 2009 | Midbass / Full-Range | 6.5 |
| 2008 | Midbass / Full-Range | 6.5 |
| 2000 | Full-Range | 4x6 |
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 GMC Savana accommodates 2 distinct speaker sizes across the model years listed in the specifications: 6.5 inch and 4x6 inch.
- The 6.5 inch mounting position is a circular cutout, and the oval 4x6 inch position reflects a different mounting geometry in the 2000 model year, indicating the rear enclosure or panel was redesigned at some point between those years.
- A 6.5 inch driver occupies a relatively compact circular footprint, meaning the mounting depth and baffle clearance behind the rear panel must accommodate a standard mid-sized woofer basket without interference from structural elements of the van body.
- The 4x6 inch oval format of the GMC Savana rear location for the 2000 model year requires an elongated mounting cutout, and the asymmetric cone area affects how evenly low-frequency waves are dispersed within the rear cabin space.
- At 6.5 inches, a driver in the rear position handles the frequency range typically spanning from approximately 60 Hz up to several kilohertz, covering the majority of the audible midrange and a portion of upper bass frequencies relevant to rear-cabin fill in a van-sized vehicle.
- The 4x6 inch driver, with a smaller total cone area than a 6.5 inch round driver, produces comparatively less acoustic output in the lower bass registers, making the rear position in the 2000 model year less suited for deep bass reproduction than the larger round format used in later years.
- Midbass speakers are designed to prioritize the lower midrange and upper bass frequencies, generally from around 80 Hz to 500 Hz, and are not intended to reproduce high frequencies, making them dependent on a separate tweeter elsewhere in the system for full spectral coverage.
- Full-range speakers integrate multiple driver elements or a single wide-range cone to reproduce frequencies from bass through treble within a single unit, making the full-range type self-sufficient within the rear mounting location without requiring additional high-frequency drivers at that position.
- The rear location in a van-body vehicle like the GMC Savana is physically separated from the front seating area by a significant cabin length, and the speaker type and size at the rear position directly affects how effectively sound reaches passengers seated toward the back.
- The compatibility of both midbass and full-range types with the 6.5 inch rear position indicates the mounting cavity dimensions are sufficient to accept the varying basket depths and magnet assemblies associated with both driver categories in that size class.
