Nissan Pickup Behind Seat Speaker Size
The Nissan Pickup behind seat location accommodates a 6.5 inch speaker size. Compatible types for the audio system include midbass and full-range replacement units. These specifications cover the years 1995 to 1997.
| Year | Type | Size (inch) |
|---|---|---|
| 1997 | Midbass / Full-Range | 6.5 |
| 1996 | Midbass / Full-Range | 6.5 |
| 1995 | 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 behind-seat location in the Nissan Pickup is a rear cabin position, physically separated from the primary listening area by the seat back, which affects both sound projection angle and the degree of acoustic interaction with the front cabin space.
- A 6.5-inch driver occupies a mid-sized cone diameter that supports a frequency range generally spanning from approximately 50 Hz to 5,000 Hz, making the cone area sufficient to move enough air for meaningful bass and midrange reproduction in an enclosed cab environment.
- The behind-seat position places the speaker at a low mounting height relative to occupant ear level, which influences the directional projection of higher frequencies while allowing lower frequencies, which are largely omnidirectional, to fill the cabin more evenly.
- The Nissan Pickup behind-seat location accommodates a 6.5-inch opening across the 1995, 1996, and 1997 model years, indicating a consistent factory cutout and baffle depth for that span.
- A midbass driver in a 6.5-inch format prioritizes the lower portion of the midrange and upper bass frequencies, typically from around 80 Hz to 500 Hz, reinforcing the body and warmth of audio reproduction rather than high-frequency detail.
- A full-range driver of 6.5 inches covers a broader spectrum than a dedicated midbass unit, using cone design and sometimes a built-in whizzer cone or dust cap geometry to extend response toward higher frequencies, compensating for the lack of a separate tweeter at the behind-seat position.
- The behind-seat location in a compact pickup truck typically offers limited enclosure depth, as the cavity behind the seat is shallow and not a sealed or ported acoustic chamber, which can influence how effectively a 6.5-inch midbass driver reproduces the lowest end of its rated range.
- Because the behind-seat position is physically behind occupants rather than at dashboard or door level, full-range drivers installed there are responsible for a wider portion of the audible spectrum without supplemental drivers at that location, placing greater demand on the driver's ability to reproduce both midrange and treble frequencies.
- The 6.5-inch cone size in a behind-seat position, relative to smaller alternatives, allows for greater cone excursion, which is the forward and backward movement of the cone that produces lower-frequency sound pressure at usable listening volumes within the cab.
