GMC Safari Rear Speaker Size
The GMC Safari rear location accommodates 4x6 inch speakers and supports a 6.5 inch speaker size. Compatible types across all configurations include full-range units as well as midbass speakers. These specifications cover the 2000 to 2005 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2005 | Full-Range | 4x6 |
| 2005 | Midbass / Full-Range | 6.5 |
| 2004 | Full-Range | 4x6 |
| 2004 | Midbass / Full-Range | 6.5 |
| 2003 | Full-Range | 4x6 |
| 2003 | Midbass / Full-Range | 6.5 |
| 2002 | Full-Range | 4x6 |
| 2002 | Midbass / Full-Range | 6.5 |
| 2001 | Full-Range | 4x6 |
| 2001 | Midbass / Full-Range | 6.5 |
| 2000 | Full-Range | 4x6 |
| 2000 | Midbass / Full-Range | 6.5 |
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 Safari accommodates 2 distinct sizes across the listed model years: 4x6 inch and 6.5 inch.
- The 4x6 inch footprint is an oval format, meaning the speaker cone area is elongated rather than circular, which affects the mounting cutout geometry and requires an oval-shaped opening in the rear panel or door.
- Oval 4x6 inch speakers are physically shallower in cone depth relative to round speakers of comparable surface area, a characteristic relevant to rear locations where mounting depth behind the panel may be limited.
- In the rear of a van-bodied vehicle such as the GMC Safari, speaker placement is typically within rear side panels or tailgate areas, where enclosure volume and surface rigidity differ from front door installations.
- The 4x6 inch size in the GMC Safari rear location is listed as compatible only with full-range drivers, meaning a single driver at that position handles the entire audible frequency spectrum without crossover division.
- Full-range drivers in a rear location reproduce frequencies from the low midrange through the upper treble from a single cone and integrated tweeter, covering roughly 80 Hz to 20 kHz depending on the specific driver.
- The 6.5 inch round format carries a larger cone area than the 4x6 oval, which generally supports greater low-frequency displacement and output at rear positions where bass reinforcement contributes to cabin sound distribution.
- The GMC Safari rear location lists midbass as a compatible type for 6.5 inch drivers, meaning a dedicated midbass driver at that position would operate within roughly 80 Hz to 500 Hz and would require a high-pass crossover to filter out higher frequencies.
- When a 6.5 inch midbass driver is used in the GMC Safari rear location, the low-to-mid frequency output from the rear panels supplements front-stage imaging by reinforcing the lower midrange across the cabin.
- The 6.5 inch size at the rear is also listed as compatible with full-range drivers, allowing a single 6.5 inch driver to handle the full spectrum at that location without a separate high-frequency driver.
- A round 6.5 inch mounting requires a circular cutout with a standardized diameter, and the rear panel of the GMC Safari must have sufficient depth clearance behind the mounting surface to accommodate the magnet and basket of a driver in that size class.
- The presence of both 4x6 inch and 6.5 inch fitments in the same rear location across the same model years indicates the rear mounting area in the GMC Safari accepts either an oval or round speaker baffle configuration.
