Additional Notes
- The 1986 Cadillac Eldorado contains three distinct speaker locations with varying size requirements, suggesting a factory audio configuration that separates frequency responsibilities across different positions within the cabin.
- Front door panels accommodate 4 inch midrange speakers, indicating a focused approach to vocal and instrumental reproduction in the front soundstage rather than full-spectrum coverage from these locations.
- Dashboard positions utilize 4x6 inch full-range speakers, which likely handle a broader frequency spectrum compared to the door-mounted midrange units, potentially serving as the primary sound source for front passengers.
- Rear deck lid positions support 6x9 inch full-range speakers, representing the largest speaker size in the factory configuration and possibly providing bass reinforcement along with mid and high frequency content for rear seat passengers.
- Replacement speakers for the front doors would need to function specifically as midrange drivers, meaning woofers or full-range speakers in this location might not integrate properly with the original system architecture.
- Upgrading the dashboard and rear deck speakers to contemporary 4x6 and 6x9 full-range models could potentially improve tonal clarity and power handling while maintaining compatibility with the factory mounting locations.
- The combination of dedicated midrange and full-range speakers throughout the cabin suggests the factory system may have employed a basic component-style approach, though without tweeters for dedicated high-frequency reproduction.
- Sound improvement efforts might prioritize the larger 6x9 inch rear deck speakers first, as their size typically allows for greater bass response and overall output compared to the smaller dashboard and door units.
