Ram 2500 Below Seats Speaker Size
The Ram 2500 below seats location accommodates an 8 inch speaker size across all listed model years. Subwoofer units serve as the compatible replacement type for the audio system at that position. These specifications cover the 2011 to 2018 model year chart range.
| Year | Type | Size (inch) |
|---|---|---|
| 2018 | Subwoofer | 8 |
| 2017 | Subwoofer | 8 |
| 2016 | Subwoofer | 8 |
| 2015 | Subwoofer | 8 |
| 2014 | Subwoofer | 8 |
| 2013 | Subwoofer | 8 |
| 2012 | Subwoofer | 8 |
| 2011 | 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 below-seats location in the Ram 2500 positions speakers in an enclosed, low-profile cavity beneath the seating structure, which constrains the available mounting depth and enclosure volume.
- An 8-inch driver in a below-seat installation occupies a physically compact vertical footprint while still producing meaningful low-frequency output, making the driver diameter a functional compromise between cone surface area and the shallow space beneath a seat.
- The 8-inch cone diameter produces a larger radiating surface than smaller drivers, which allows for greater air displacement and lower frequency extension before distortion increases at high output levels.
- Subwoofers are dedicated low-frequency transducers, typically reproducing frequencies in the range of approximately 20 Hz to 200 Hz, operating well below the range handled by midrange drivers or tweeters.
- In a below-seat location, a subwoofer relies on the surrounding seat structure and floor cavity to act as a partial acoustic boundary, influencing bass loading and the effective output level perceived by occupants.
- The Ram 2500 below-seats position, across the 2011 through 2018 model years listed in the specifications, accepts only a subwoofer type, indicating the location serves a dedicated bass reproduction role rather than a full-range function.
- An 8-inch subwoofer in an under-seat position radiates low-frequency energy omnidirectionally, as bass wavelengths are long relative to the driver size, meaning the perceived bass is not strongly tied to the physical direction of the driver cone.
- The mounting cutout for an 8-inch driver requires a baffle opening of approximately 7.25 inches in diameter, with additional clearance needed around the perimeter for the basket flange, which affects compatibility with the existing seat cavity dimensions in the Ram 2500 + below-seats location.
- Subwoofers require a sealed or ported enclosure to perform efficiently, and in a below-seat installation the enclosure geometry is largely defined by the fixed cavity formed by the seat frame and the vehicle floor rather than a separate aftermarket box.
- The consistent 8-inch subwoofer specification across all listed model years reflects a stable mounting cavity dimension throughout the 2011-2018 production range of the Ram 2500.
