Additional Notes
- The 1989 Subaru Justy incorporates a dual-size speaker configuration, with 4x6 inch openings in the dashboard locations and 5.25 inch circular positions in the rear door panels, suggesting different acoustic roles within the factory audio design.
- Dashboard positions accommodate only full-range speakers, while rear door panel locations accept either midbass or full-range types, providing flexibility in component selection based on desired frequency response characteristics.
- Replacing dashboard speakers might take precedence given their typical placement closer to listeners in the cabin, potentially offering more immediate impact on perceived audio quality compared to rear-mounted positions.
- The oval 4x6 inch format in dashboard locations represents a space-efficient design common in compact vehicle applications, balancing cone area against available mounting depth constraints.
- Rear door panel compatibility with midbass drivers suggests sufficient mounting depth and enclosure volume for handling lower frequency reproduction, which could enhance bass response when paired with appropriate components.
- A single DIN radio opening maintains compatibility with aftermarket head units, potentially allowing integration of modern source components with improved amplification for driving replacement speakers.
- Full-range speakers in both positions would maintain factory-style coverage patterns, while introducing dedicated midbass drivers in rear locations could create a more specialized frequency distribution across the listening space.
- The combination of different speaker sizes may allow for natural frequency division, with smaller dashboard units handling midrange and upper frequencies while larger rear speakers manage lower midrange content.
