The Ram 1500 center dash location accommodates a 3.5 inch speaker size across all listed model years. Full-range units are the compatible audio system type for the center dash. These specifications cover the 2011 to 2018 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 Ram 1500 sits at the uppermost forward point of the cabin interior, positioning the speaker at approximately ear level and near the horizontal centerline of the windshield.
A center dash mounting position places the driver and front passenger at roughly equal distances from the speaker, which makes the location acoustically suited for centered soundstage imaging.
The 3.5 inch diameter corresponds to a small driver cone area, which limits low-frequency excursion capability but allows the speaker to reproduce upper-bass, midrange, and treble frequencies with minimal cabinet volume requirements.
Shallow dash cavities are a common constraint in center dash installations, and a 3.5 inch driver typically carries a shallow mounting depth that aligns with the limited space behind the dash panel in the Ram 1500.
A full-range speaker type is designed to reproduce the entire audible frequency spectrum from a single driver, covering low, mid, and high frequencies without requiring a crossover network or additional components.
In a center dash position, a full-range driver handles dialogue and vocal frequencies in the midrange band, which occupies roughly 500 Hz to 4 kHz, the range most associated with speech intelligibility.
The Ram 1500 center dash full-range speaker compatibility indicates no passive crossover filtering is needed at the head unit or amplifier output for the center position across the 2011 through 2018 model years.
A 3.5 inch full-range driver in a dash-mounted position exhibits a relatively wide dispersion pattern at lower frequencies, but directional narrowing occurs at higher frequencies, which is a standard acoustic behavior of small cone drivers.
The center dash location sits forward of both occupants, meaning the speaker fires rearward into the cabin, which contributes to a diffused sound field rather than a direct or pointed acoustic projection.
