Additional Notes
- The 1998 Ford Expedition uses 6x8 inch speakers in both front and rear door panels, with an additional 8 inch woofer in the rear side panel position.
- Door panel speakers are designated for full-range use, suggesting they handle both mid-range frequencies and higher frequencies without requiring separate tweeters.
- The rear side panel position accommodates a woofer, indicating this location focuses on lower frequency reproduction to complement the door-mounted full-range units.
- Upgrading the door panel speakers may provide the most noticeable improvement in overall sound quality, as these full-range units handle the majority of the audible frequency spectrum.
- The 6x8 inch oval configuration in the doors allows for greater cone area compared to round 6.5 inch speakers while fitting within similar mounting locations.
- Aftermarket speakers maintaining the 6x8 inch form factor would integrate into the existing mounting points without requiring modifications to the door panels.
- The dedicated woofer position suggests the factory audio design included some level of frequency distribution, with the 8 inch unit handling bass frequencies separately from the door speakers.
- Radio replacement options include both single DIN and double DIN head units, providing flexibility for aftermarket stereo installations with varying feature sets and display sizes.
