Dodge Dakota Behind Seat Speaker Size
The Dodge Dakota behind seat location accommodates a 6.5 inch speaker size and 5x7 inch speakers across the model's production span. Compatible speaker types for these units include full-range and midbass configurations. These specifications cover the years 1990 to 1999.
| Year | Type | Size (inch) |
|---|---|---|
| 1999 | Midbass / Full-Range | 6.5 |
| 1998 | Midbass / Full-Range | 6.5 |
| 1997 | Midbass / Full-Range | 6.5 |
| 1996 | Full-Range | 5x7 |
| 1995 | Full-Range | 5x7 |
| 1994 | Full-Range | 5x7 |
| 1993 | Full-Range | 5x7 |
| 1992 | Full-Range | 5x7 |
| 1991 | Full-Range | 5x7 |
| 1990 | Full-Range | 5x7 |
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 behind-seat location in the Dodge Dakota places speakers in a confined rear cavity, typically behind the cab's rear wall or within a shallow enclosure beneath or behind the seat structure, which affects cone excursion and bass loading.
- A 6.5-inch driver occupies a circular mounting cutout, and at that diameter the cone surface area supports reproduction of lower midrange and upper bass frequencies, generally spanning from around 60 Hz up through several kilohertz depending on cone material and crossover configuration.
- The 5x7-inch format is an oval driver, and the elongated footprint fits mounting locations engineered for non-circular cutouts, with an effective radiating area roughly comparable to a 6.5-inch round driver, producing a similar but not identical frequency response profile.
- Full-range speakers are designed to reproduce the entire audible spectrum from a single driver, incorporating a cone for low and mid frequencies and often a small integrated tweeter or whizzer cone for high-frequency extension, making them suited to locations without a dedicated tweeter mount.
- Midbass speakers are optimized for the lower portion of the midrange and upper bass frequencies, typically between roughly 80 Hz and 500 Hz, and are not intended to reproduce high frequencies independently, so a separate tweeter elsewhere in the cabin is required when midbass drivers are used.
- The behind-seat position in a compact pickup truck places the speaker surface area facing generally upward or rearward relative to seated occupants, which can reduce high-frequency directionality toward the front listening position and makes the extended treble response of full-range drivers less acoustically critical than in dash or door locations.
- The 1997-1999 Dodge Dakota behind-seat location accommodating a 6.5-inch driver reflects a change from the oval format used in earlier model years, indicating a revised mounting baffle or bracket design beginning with the 1997 model year.
- The 5x7-inch specification applying to the 1990 through 1996 model years indicates a consistent mounting cavity geometry across that production span, with the oval cutout dimensions remaining unchanged in the behind-seat panel.
- In the behind-seat application, midbass drivers work in conjunction with the cabin's acoustic boundaries, where the seat structure and rear cab wall can act as partial low-frequency loading surfaces, influencing the effective bass output of a 6.5-inch midbass cone.
- The oval 5x7-inch format is limited to full-range compatibility in the specifications, which reflects that midbass-only drivers in an oval format are far less common as a product category compared to round midbass drivers.
