Additional Notes
- The 1987 Buick Century uses two distinct speaker sizes across its audio locations, with smaller 4x6 inch units positioned in the dashboard and larger 6x9 inch speakers mounted in the rear deck lid area.
- Both factory locations accept full-range speaker designs, which handle the entire frequency spectrum from bass through treble without requiring separate tweeters or crossover components.
- The rear deck lid position typically receives priority during upgrades because the 6x9 inch format provides greater cone surface area, potentially allowing for increased bass response and overall output compared to the dashboard position.
- The dashboard speakers operate in a more confined acoustic environment, which may limit their low-frequency output regardless of replacement quality, while the rear deck location benefits from coupling with the trunk cavity.
- The single DIN radio opening indicates a standardized head unit size that measures approximately 2 inches in height, which remains compatible with many aftermarket receivers should the audio source require updating.
- Aftermarket speakers in these sizes often include coaxial designs with integrated tweeters, which would maintain the full-range capability while potentially improving high-frequency clarity over the original equipment.
- The 4x6 inch format represents a non-round speaker shape that may offer fewer aftermarket options compared to standard round sizes, though major manufacturers continue producing replacements in this configuration.
