Toyota Tundra Behind Rear Seat Speaker Size
The Toyota Tundra behind rear seat location accommodates an 8 inch speaker size. The compatible audio system type for the replacement is a subwoofer. These specifications chart the years 2007 through 2015.
| Year | Type | Size (inch) |
|---|---|---|
| 2015 | Subwoofer | 8 |
| 2014 | Subwoofer | 8 |
| 2013 | Subwoofer | 8 |
| 2012 | Subwoofer | 8 |
| 2011 | Subwoofer | 8 |
| 2010 | Subwoofer | 8 |
| 2009 | Subwoofer | 8 |
| 2008 | Subwoofer | 8 |
| 2007 | Subwoofer | 8 |
Speaker Types
| Type | Description |
|---|---|
| Subwoofer | A large driver for the lowest bass notes, typically from about 20 Hz to 120 Hz. It is usually installed in a separate enclosure and works alongside the other speakers. |
Additional Notes
- The behind-rear-seat location in the Toyota Tundra positions the speaker enclosure between the rear seating surface and the back wall of the cab, a space that is physically constrained in depth and width relative to trunk or cargo floor installations.
- An 8-inch driver in a subwoofer application is sized to move sufficient air volume for low-frequency reproduction, typically covering a range from approximately 20 Hz to 200 Hz, without requiring the larger enclosure volume that a 10-inch or 12-inch subwoofer demands.
- The behind-rear-seat cavity in a truck cab tends to be shallow, and an 8-inch subwoofer is dimensionally suited to shallower enclosures compared to larger woofer diameters, which require greater internal volume to maintain accurate bass output.
- A subwoofer is a dedicated low-frequency transducer, meaning the cone excursion and motor assembly are engineered specifically to handle the high displacement demands of bass frequencies rather than reproducing midrange or high-frequency content.
- The Toyota Tundra behind-rear-seat position places the subwoofer behind the occupants, a rearward mounting orientation where low-frequency waves-being largely omnidirectional at bass frequencies-propagate throughout the cab regardless of the driver's facing direction.
- Across the 2007 through 2015 model years of the Toyota Tundra, the behind-rear-seat location consistently specifies an 8-inch mounting diameter, indicating a uniform cutout or baffle dimension at that position across the generation.
- An 8-inch subwoofer cone surface area produces enough pistonic displacement for audible bass output in an enclosed cab environment without the mounting footprint required by larger subwoofer diameters.
- The subwoofer type designation, as distinct from a full-range woofer, indicates the driver is not expected to reproduce frequencies above the bass band, and in a vehicle installation the crossover point is typically set between 80 Hz and 120 Hz to separate subwoofer duties from mid-bass drivers elsewhere in the system.
- The physical space behind the rear seat of a crew or extended cab truck limits both the enclosure depth available to the subwoofer and the total internal air volume, factors that directly affect the tuning and low-frequency extension achievable by an 8-inch driver in the Toyota Tundra behind-rear-seat location.
