The Lincoln MKX rear door panel accommodates a 6x8 inch speaker size, with all locations supporting the same speaker across the model's production run. Full-range units represent the compatible audio system type for the replacement chart. These specifications cover the 2007 to 2015 model years.
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 is a mounted position within the vehicle's interior door structure, placing speakers at a low-to-mid height along the sides of the rear passenger cabin.
Door panel cavities impose fixed dimensional constraints on speaker diameter and depth, requiring a speaker footprint that matches the molded mounting ring or bracket built into the panel.
A 6x8 inch oval speaker format has a larger cone surface area than a standard 6.5 inch round driver, which increases air movement and low-frequency output within the physical space of a door panel cutout.
The oval geometry of a 6x8 inch driver allows a wider mounting footprint without requiring significantly greater depth, a relevant factor in door panel installations where cavity depth behind the mounting surface is limited.
Because the rear door panel positions speakers behind and beside seated rear passengers, the lateral and rearward placement affects how sound reaches the listening position, with low- and mid-range frequencies being less directionally sensitive than high frequencies.
The Lincoln MKX rear door panel position accommodates a 6x8 inch full-range speaker across the 2007 through 2015 model years, establishing a consistent mounting dimension across the entire listed range.
A full-range speaker type is a single driver designed to reproduce low, mid, and high frequencies without the assistance of a separate tweeter or woofer in the same location.
In a rear door panel location, a full-range driver handles the complete audible spectrum from that position, covering roughly 50 Hz to 20 kHz within a single cone and surround assembly.
The 6x8 inch cone area supports extended bass reproduction relative to smaller driver formats, which is relevant in a rear door panel position where reinforcement of lower frequencies contributes to the overall soundstage perceived by rear-seat occupants.
Full-range compatibility in the rear door panel means no crossover network is required at the speaker level for basic operation, as the single driver manages frequency distribution internally through its mechanical design.
