GMC Sierra Center Console Speaker Size
The GMC Sierra center console accommodates a 6.5 inch speaker size across all listed model years. Compatible speaker types for the location include midbass and full-range units. The specifications cover the 2014 to 2018 model range.
| Year | Type | Size (inch) |
|---|---|---|
| 2018 | Midbass / Full-Range | 6.5 |
| 2017 | Midbass / Full-Range | 6.5 |
| 2016 | Midbass / Full-Range | 6.5 |
| 2015 | Midbass / Full-Range | 6.5 |
| 2014 | 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 GMC Sierra center console speaker location positions drivers centrally within the cabin, between the front seats, which places audio output at a low point relative to seated occupants.
- A center console placement is generally closer to the floor than to ear level, which influences how low and mid frequencies are perceived by front-seat passengers.
- The 6.5 inch diameter is a mid-sized driver format that handles frequencies roughly spanning from around 60 Hz to 5,000 Hz, making it capable of reproducing bass and midrange content from a console-mounted position.
- A 6.5 inch cone surface area generates enough air displacement to reproduce midbass frequencies with meaningful output, which suits the acoustically enclosed space around a center console.
- The GMC Sierra center console mounting accepts a 6.5 inch speaker across the 2014 through 2018 model years, a dimensional consistency relevant to physical fitment when replacing drivers.
- Midbass drivers are designed to handle the lower portion of the midrange and upper bass frequencies, typically between roughly 80 Hz and 500 Hz, without the full-spectrum demands placed on a full-range driver.
- Full-range drivers are built to reproduce a wide frequency span within a single cone unit, covering bass, midrange, and a degree of high-frequency content from one driver at the console location.
- The center console mounting orientation typically directs speaker output upward or at an angle toward the front occupants rather than forward-facing, which affects the directional character of the sound field.
- A midbass driver in the center console position can reinforce low-frequency content in the front soundstage without requiring a separate subwoofer enclosure in that area of the cabin.
- Full-range compatibility at the center console position means a single 6.5 inch driver can reproduce all audible content assigned to that channel without requiring a crossover to a separate tweeter at that location.
