Jeep Wagoneer Rear Door Panel Speaker Size
The Jeep Wagoneer rear door panel accommodates a 5.25 inch speaker size in that location. Compatible types for the rear door panel include midbass and full-range audio units. These specifications cover the 1990 system year.
| Year | Type | Size (inch) |
|---|---|---|
| 1990 | Midbass / Full-Range | 5.25 |
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 rear door panel location in the 1990 Jeep Wagoneer accommodates a speaker mounted within the door's interior trim panel, a position that places the driver cone behind a grille surface and within a relatively shallow cavity bounded by the door's inner and outer metal skins.
- Door panel mounting positions are subject to spatial constraints from window mechanisms, door hardware, and structural reinforcements, which affect available depth and baffle area for the speaker basket and magnet assembly.
- A 5.25-inch speaker occupies a mid-sized cone diameter that produces a balance between low-frequency extension and upper-midrange clarity, making the cone area sufficient to move enough air for bass fundamentals while remaining small enough to reproduce vocal and instrumental midrange detail.
- The 5.25-inch diameter places the speaker's effective frequency range roughly between 80 Hz and 18 kHz, depending on the driver's construction, which covers a broad portion of the audible spectrum from the rear door position.
- In a rear door panel location, a 5.25-inch driver is positioned at a relatively low height along the vehicle's interior side wall, which affects the angle of sound projection toward rear-seat occupants and the degree of low-frequency reinforcement from boundary loading near the door sill.
- The midbass type, listed as compatible for the 1990 Jeep Wagoneer rear door panel, is a driver designed to handle the lower portion of the midrange spectrum and upper bass frequencies, typically operating between approximately 80 Hz and 500 Hz, and is built with a stiffer suspension to manage cone excursion under higher power in that range.
- A midbass driver in a door panel location takes advantage of the enclosure effect created by the door cavity behind the cone, which can reinforce low-frequency output by providing a sealed or semi-sealed air volume that extends bass response compared to free-air mounting.
- The full-range type, also listed as compatible for the 1990 Jeep Wagoneer rear door panel, refers to a single-driver design intended to reproduce a wide frequency span without a dedicated crossover, typically incorporating a whizzer cone or treated surround to extend high-frequency dispersion from a single motor assembly.
- Full-range drivers in a rear door panel position direct sound upward and inward toward the cabin, with the high-frequency content of a full-range cone being more directional than the low-frequency content, which radiates more broadly regardless of driver orientation.
- The door panel baffle created by the trim panel itself acts as an acoustic boundary for the speaker, and the fit of a 5.25-inch frame to the mounting cutout determines how effectively the baffle separates the front and rear waves of the cone, which directly influences bass response and cancellation behavior.
