The Ford F-150 center dash location accommodates a 3.5 inch speaker size and 6.5 inch speakers, with each speaker position supporting full-range audio units as the compatible type. The system accepts full-range replacement drivers across all applicable model years. These specifications cover the 2017 to 2025 range of 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 center dash location in the Ford F-150 sits along the central axis of the instrument panel, positioning the speaker equidistant from the left and right seating positions to produce a centered soundstage for front-cabin occupants.
A center dash mounting position places the speaker facing rearward into the cabin from a relatively shallow dashboard cavity, which constrains the depth available for speaker basket and magnet assembly.
The 3.5 inch driver size, found across the 2019 through 2025 model years and also listed as an option for 2017 and 2018, is a small-diameter unit whose limited cone surface area is suited to upper-midrange and high-frequency reproduction rather than deep bass extension.
At 3.5 inches, the cone excursion required to move significant air volume at low frequencies is mechanically impractical, so the frequency response of a driver at this diameter typically begins rolling off below several hundred hertz under real-world conditions.
The 6.5 inch driver size, listed for the Ford F-150 center dash in 2017 and 2018, has a substantially larger cone area that allows greater air displacement and extends usable low-frequency output compared to a 3.5 inch unit in the same position.
A 6.5 inch driver in a center dash location requires a larger cutout diameter and greater mounting depth than a 3.5 inch driver, indicating that the dashboard cavity in the applicable 2017 and 2018 F-150 configurations was dimensioned to accommodate the larger chassis.
Full-range is the sole compatible speaker type listed across all model years and both sizes, meaning the drivers used in the center dash position are designed to reproduce multiple frequency bands - typically covering some portion of bass, midrange, and treble - within a single driver unit.
A full-range driver in a center dash position handles broad-spectrum audio without requiring a separate crossover network to divide frequencies before they reach the driver, which is consistent with a physically constrained single-speaker mounting location.
The center dash position, due to nearness to the windshield and the reflective surfaces of the instrument panel, is subject to acoustic reflections that can affect high-frequency dispersion and imaging relative to door or pillar-mounted positions.
The 2018 model year carries 2 distinct size entries - 3.5 inch and 6.5 inch - for the center dash location, indicating that different trim or build configurations of the 2018 F-150 used different speaker cutout dimensions in the same position.
The same dual-entry pattern present in 2018 also appears in 2017, where both 6.5 inch and 3.5 inch full-range drivers are listed, reflecting trim-dependent variation in the speaker cavity dimensions for those model years.
