The Ford Excursion rear door panel accommodates a 6x8 inch speaker size in each location. Full-range units are the compatible audio system replacement types for the rear door panel. These specifications cover the 2000 to 2005 model range.
A single driver that reproduces bass through treble without a separate crossover network. It is the simplest replacement option and is common in factory audio systems.
Additional Notes
The rear door panel location in the Ford Excursion places speakers within the lower section of the door trim, positioning audio output toward the lower cabin area rather than at ear level for seated occupants.
Door panel mounting in a large-body SUV such as the Excursion involves an enclosure formed by the door cavity itself, which affects bass response and low-frequency resonance behavior of any installed speaker.
The 6x8 inch oval dimensions accommodate a larger cone surface area than a standard round 6.5 inch driver, which increases air displacement and supports stronger low-to-mid frequency output within the rear door panel cavity.
The oval shape of a 6x8 inch driver is a packaging solution designed to fit the constrained vertical depth typical of door panel mounting locations while still achieving cone area comparable to larger round drivers.
The Ford Excursion rear door panel, as a full-range speaker location across all 6 model years in the specifications, is designated to handle the complete audible frequency spectrum from low bass through high treble from a single driver position.
Full-range drivers reproduce frequencies roughly spanning 50 Hz to 20 kHz, meaning a single speaker installed in the rear door panel is responsible for bass, midrange, and treble reproduction at that position without a dedicated crossover network dividing those duties.
The rear door panel position, being low and rearward in the cabin, means a full-range driver there contributes primarily to spatial fill and low-frequency support, as high-frequency directional sound from a low mounting point may be partially absorbed by seating and occupants.
A 6x8 inch full-range driver in a door panel installation relies on the door cavity acting as a passive enclosure, and the volume and sealing quality of that cavity directly influence the driver's bass extension and overall frequency balance.
