Additional Notes
- The 1987 Ford Thunderbird uses three different speaker sizes across its factory audio system, with dashboard locations accommodating the smallest diameter speakers at 3.5 inches.
- Front door panel speakers may benefit from midbass drivers that can handle lower frequency reproduction more effectively than standard full-range units, particularly given the 5.25 inch size allocation.
- Rear deck lid positions utilize oval 6x8 inch configurations, which typically provide greater cone area compared to round 6.5 inch alternatives while fitting within similar mounting footprints.
- Dashboard speakers often receive priority for replacement when clarity in mid and high frequencies is the primary concern, as these positions generally direct sound toward the listening area more efficiently than rear locations.
- Component speaker systems could be installed in the front door locations to separate tweeter and woofer functions, though this would require additional mounting considerations beyond the factory full-range setup.
- Power handling capacity becomes relevant when replacing factory speakers, as aftermarket options frequently offer higher wattage ratings that may better match modern head unit outputs.
- The single DIN radio slot follows standard dimensions that accept most aftermarket head units without requiring dashboard modifications or adapter kits.
- Sensitivity ratings on replacement speakers influence volume output levels, with higher sensitivity units producing more sound from the same amplifier power input.
