Dodge Colt Rear Deck Lid Speaker Size
The Dodge Colt rear deck lid accommodates 5.25 inch speakers, 6.5 inch units, and a 6x9 inch speaker size across the model's production span. Compatible speaker types across these sizes include full-range and midbass units. These specifications cover the years 1985 to 1994.
| Year | Type | Size (inch) |
|---|---|---|
| 1994 | Full-Range | 6x9 |
| 1993 | Full-Range | 6x9 |
| 1990 | Midbass / Full-Range | 5.25 |
| 1989 | Midbass / Full-Range | 5.25 |
| 1988 | Midbass / Full-Range | 5.25 |
| 1987 | Midbass / Full-Range | 5.25 |
| 1986 | Midbass / Full-Range | 6.5 |
| 1985 | 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 Dodge Colt rear deck lid is a horizontal mounting surface positioned at the base of the rear window, behind the rear seating area, where speakers fire upward toward the cabin interior.
- Deck lid installations typically place speakers flush within the panel, meaning the mounting depth and cutout diameter of any replacement driver must conform precisely to the available cavity dimensions of the location.
- The 6x9 inch oval format, specified for the Dodge Colt in 1993 and 1994, has a larger radiating surface area than a round 6.5 inch driver, which allows for greater low-frequency displacement and louder output from a single driver position.
- Only full-range compatibility is listed for the 6x9 inch positions in the Dodge Colt rear deck lid, meaning the driver installed must reproduce the full audible spectrum independently, from low bass through high treble, without the support of a separate tweeter at the same location.
- The 5.25 inch round driver, specified across the 1986-1990 model years, has a smaller cone area than both the 6x9 oval and the 6.5 inch round, which correlates with a reduced low-frequency output capability but a relatively higher natural resonant frequency.
- The 5.25 inch positions in the Dodge Colt rear deck lid list midbass and full-range as compatible types, indicating the cutout accommodates drivers specialized for the upper bass and lower midrange frequencies, as well as drivers intended to cover the full spectrum.
- A midbass driver is designed to reproduce frequencies roughly between 80 Hz and 500 Hz, prioritizing accurate bass and lower midrange reproduction without attempting to extend response into the upper treble region.
- The 6.5 inch round format specified for the Dodge Colt rear deck lid in 1985 and 1986 occupies a mid-point between the 5.25 inch and 6x9 inch formats, with a cone diameter that supports stronger bass extension than the 5.25 inch while remaining within a compact round cutout.
- The Dodge Colt 6.5 inch rear deck lid location shares the same compatible types - midbass and full-range - as the 5.25 inch positions, placing both sizes in an acoustic role oriented toward bass and midrange reinforcement within the cabin.
- The rear deck lid position, being physically close to the trunk cavity, can interact with the resonant air volume behind the rear seats, influencing bass reproduction from any driver mounted there regardless of size.
- Full-range drivers installed in an overhead-firing deck lid position distribute sound upward and toward the front of the cabin, where the reflected acoustic energy from the rear window and headliner shapes the perceived frequency balance for rear passengers.
