Additional Notes
- The 1990 Eagle Summit positions midrange speakers in the dashboard at 4 inches, which tends to focus on vocal clarity and mid-frequency reproduction rather than full-spectrum audio coverage.
- Rear door panel locations accommodate 6x9 inch full-range speakers, suggesting these positions could handle the majority of frequency response duties when upgraded from factory components.
- The dashboard midrange units would likely benefit from replacement primarily when seeking improved vocal presence and instrument separation in the front soundstage.
- Full-range speakers in the rear door panels can reproduce bass, midrange, and treble frequencies without requiring separate tweeters or woofers, potentially simplifying the upgrade process.
- The single DIN radio opening allows for aftermarket head unit installation, which could provide additional power output and better signal processing for replacement speakers.
- Replacing the rear door speakers might yield more noticeable sound improvement than dashboard upgrades due to the larger surface area and broader frequency capabilities of 6x9 inch components.
- The combination of dedicated midrange speakers up front and full-range units in the rear suggests a factory configuration that prioritized front-to-rear sound distribution over purely front-focused staging.
