The Ram 5500 rear side panel accommodates a 6x9 inch speaker size across all listed model years. Full-range units represent the compatible audio system type for the location. These specifications cover the 2011 to 2016 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 rear side panel location in the Ram 5500 accommodates 6x9 inch speakers across all listed model years from 2011 through 2016.
A 6x9 inch oval speaker footprint requires an elongated mounting cutout, and the enclosure depth behind the rear side panel must be sufficient to clear the speaker's basket and magnet assembly.
The oval geometry of a 6x9 inch driver produces a larger cone surface area than a standard round 6.5 inch speaker, which increases low-frequency displacement capability within the same general mounting space.
Rear side panel locations typically position speakers at lower height and angled toward the cabin interior, which influences the dispersion pattern of mid and high frequencies reaching rear passengers.
The 6x9 inch size at the Ram 5500 rear side panel supports extended bass reproduction, as the larger cone area allows the driver to move more air at lower frequencies than smaller diameter alternatives.
Full-range speakers are designed to reproduce the entire audible frequency spectrum - typically from approximately 50 Hz to 20 kHz - from a single driver unit.
A full-range driver incorporates a woofer cone for low and mid frequencies along with an integrated tweeter element, such as a whizzer cone or dome tweeter, to extend high-frequency output.
The rear side panel position places full-range drivers in a zone where low- and mid-frequency reinforcement contributes to overall cabin sound pressure level, particularly for rear-seat occupants.
Because full-range speakers handle the complete frequency spectrum without requiring a crossover network, the Ram 5500 rear side panel installation does not require additional passive crossover components for a direct replacement.
The mounting depth available behind a side panel in a commercial truck body like the Ram 5500 can vary depending on interior trim thickness and structural framing, making basket depth a relevant measurement for physical fitment of a 6x9 inch full-range driver.
