The Ram 3500 center dash location accommodates a 3.5 inch speaker size across all listed model years. Full-range units are the compatible type for the audio system in this position. These specifications cover the 2011 to 2018 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 center dash location in the Ram 3500 positions a speaker at the top-center of the instrument panel, placing the driver at a relatively equal distance from the sound source regardless of seating position across the cabin.
A center dash mounting point is typically a shallow, constrained enclosure with limited depth behind the grille, which restricts the physical size of compatible drivers and the available air volume for cone excursion.
The 3.5-inch diameter specified across all listed model years reflects a driver size suited to the spatial constraints of a center dash cavity, where larger cone diameters would not fit within the shallow dashboard structure.
At 3.5 inches, the cone area is relatively small, which shifts the effective output range toward upper midrange and high-frequency reproduction, as smaller diameters move less air at low frequencies.
The center dash position places the speaker near ear level for front-seat occupants, making midrange and upper-frequency accuracy particularly relevant since vocal and presence frequencies are prominent in the forward soundstage.
Full-range drivers are designed to reproduce a wide span of audible frequencies within a single driver unit, combining a main cone with an integrated dust cap or whizzer cone to extend high-frequency response.
In a center dash application, a full-range driver serves as a single point of frequency reproduction without the support of a crossover network, handling both midrange and treble content from one cone.
The Ram 3500 center dash speaker mounting uses a fixed baffle integrated into the dashboard structure, meaning the acoustic back-volume and baffle dimensions are determined by the vehicle's existing design rather than by the installer.
A 3.5-inch full-range driver in the center dash of the Ram 3500 operates in a position that reinforces center-channel imaging, as the driver is equidistant between the left and right sides of the cabin.
