Additional Notes
- The 1991 Toyota Tercel front door panels accommodate two distinct speaker sizes, with a 4 inch midrange position and a larger 6.5 inch location that accepts either midbass or full-range drivers.
- Rear deck lid positions are equipped with 6.5 inch openings compatible with midbass or full-range speakers, matching the larger front door size.
- The dual front door speaker configuration suggests a factory setup that may have separated frequency ranges, with the smaller 4 inch location handling midrange frequencies while the 6.5 inch position covered lower frequencies.
- Upgrading the 6.5 inch locations might provide more noticeable bass response improvements compared to replacing the 4 inch midrange speakers, given the larger cone area available for moving air.
- Full-range 6.5 inch speakers could potentially handle both midrange and bass frequencies without requiring the 4 inch speakers to remain active, though component speaker systems might utilize both positions.
- The radio head unit accepts both single DIN and double DIN sizing, offering flexibility for aftermarket stereo installations that could drive upgraded speakers more effectively.
- Midbass drivers in the 6.5 inch positions would typically require crossover components or an external amplifier to prevent high-frequency distortion, while full-range options operate across a broader frequency spectrum.
- The rear deck 6.5 inch speakers may contribute to overall cabin sound fill, though their placement typically provides less direct sound staging compared to front-mounted drivers.
