Chevrolet Metro Rear Deck Lid Speaker Size
The Chevrolet Metro rear deck lid accommodates a 6.75 inch speaker size across all listed model years. Compatible types for the location include midbass and full-range speakers. The specifications cover the years 2000 to 2001.
| Year | Type | Size (inch) |
|---|---|---|
| 2001 | Midbass / Full-Range | 6.75 |
| 2000 | Midbass / Full-Range | 6.75 |
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 deck lid location in the Chevrolet Metro positions speakers horizontally within a flat, enclosed panel at the rear of the passenger cabin, where sound radiates upward toward the cabin ceiling and rearward glass before dispersing into the listening area.
- A deck lid mounting surface is typically a shallow, flat plane, which limits the depth clearance available for speaker baskets and requires attention to magnet and basket depth when selecting a compatible driver.
- The 6.75-inch diameter specification refers to the outer frame measurement of the speaker, which corresponds to a cone diameter capable of moving sufficient air volume to reproduce lower midrange and upper bass frequencies effectively.
- At the rear deck lid position, a 6.75-inch driver benefits from the acoustic loading effect of the enclosed trunk cavity beneath the deck, which can reinforce low-frequency output compared to the same driver mounted in an open-baffle or door location.
- The midbass type is a driver engineered to handle the lower portion of the midrange band and the upper bass register, generally covering a range from approximately 80 Hz to 500 Hz, with a cone and surround tuned for controlled excursion under higher power input at those frequencies.
- In a rear deck lid position, a midbass driver operates at a distance from the front listening position, meaning the low frequencies produced travel a longer path and blend with front-channel sources rather than delivering precise stereo imaging.
- The full-range type is a single driver designed to reproduce a wide frequency band, typically spanning from approximately 60 Hz to 20 kHz, by incorporating a main cone for low-to-mid frequencies and often a passive radiating element or whizzer cone for high-frequency extension.
- Mounted on the rear deck lid of the Chevrolet Metro, a full-range 6.75-inch driver covers both the midbass content and upper harmonic frequencies without requiring a separate tweeter, which is relevant in a location where multi-driver component installations may be spatially constrained.
- The rear deck lid surface in a vehicle of the Metro's class is generally a thin sheet metal or composite panel, and the resonance characteristics of the panel can influence the perceived output of a driver mounted within, particularly in the upper bass frequencies where panel vibration is most pronounced.
- Both the 2000 and 2001 model years share the same 6.75-inch size and the same two compatible driver types, indicating dimensional and acoustic consistency across the two model years at the rear deck lid location.
