Additional Notes
- The factory audio system in the 1987 Ford Mustang includes four distinct speaker locations with varying size requirements that may influence replacement priority based on listening position and acoustic contribution.
- Dashboard speakers at 3.5 inches are limited to full-range drivers, which typically handle mid and high frequencies but may lack bass response due to the small cone area and mounting location constraints.
- Front door panel positions accommodate 5.25 inch speakers with compatibility for either midbass or full-range types, potentially offering flexibility in system configuration depending on whether a separate tweeter setup is planned.
- Both rear deck lid and rear door panel locations utilize the same 6x8 inch oval format with full-range driver compatibility, suggesting these positions were designed to provide broader frequency coverage in the rear soundstage.
- The larger 6x8 inch speakers in rear positions generally provide better low-frequency output compared to the smaller dashboard units, though their oval shape may present different mounting and acoustic characteristics than round drivers.
- Upgrading front door speakers might take precedence since these positions are closer to front seat occupants and support midbass drivers that can reproduce lower frequencies more effectively than dashboard units.
- Full-range speakers selected for any location would need to balance midrange clarity with whatever bass extension the mounting depth and enclosure volume allow, which varies considerably between dashboard, door, and deck installations.
- The dual compatibility of front doors suggests that pairing midbass drivers with separate tweeters could create a component system, while rear positions would likely remain full-range to maintain rear fill.
