Additional Notes
- The 1986 Cadillac Seville features three distinct speaker locations with varying sizes and functional roles in the audio system.
- Front door panels accommodate 4-inch midrange speakers, which typically handle vocal frequencies and mid-spectrum audio content rather than the full frequency range.
- Dashboard positions utilize 4x6-inch full-range speakers that process the complete audio spectrum from bass through treble frequencies.
- Rear deck lid installations support larger 6x9-inch full-range speakers, which often provide enhanced bass response due to their increased surface area compared to smaller units.
- The midrange designation for door speakers suggests a factory configuration where bass reproduction may have been allocated to other locations in the original audio design.
- Upgrading the rear deck speakers could potentially deliver noticeable improvements in low-frequency output given their larger cone area and full-range capability.
- Dashboard speaker replacements might be prioritized for clarity enhancement since these units sit closer to occupants and handle the complete frequency spectrum.
- The combination of dedicated midrange and full-range speakers indicates a multi-speaker approach to distributing different frequency ranges throughout the cabin.
- Replacement options for the 4x6-inch dashboard location tend to be more limited in the aftermarket compared to standard round sizes, which could influence component selection.
