The Dodge Dart rear door panel accommodates a 6x9 inch speaker size in each location. Full-range units are the compatible type for the audio system in the rear door panel. These specifications cover the 2013 to 2016 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 rear door panel location in the Dodge Dart positions speakers within the lower portion of the door cavity, mounted against the inner door skin behind a grille or trim panel, which places the drivers at roughly seat-level height.
A seat-level mounting position in a rear door panel typically directs sound upward and inward toward the cabin, with the door structure itself acting as part of the enclosure affecting bass response and overall output.
The 6x9 inch oval format is a common rear door fitment because the elongated shape accommodates the irregular vertical-to-horizontal space ratios often found in door cavities while maximizing cone surface area within those constraints.
The larger cone surface area of a 6x9 inch driver relative to smaller round formats produces greater air displacement, which supports stronger low-frequency output without requiring a dedicated subwoofer in the rear door location.
The 6x9 inch size in the Dodge Dart rear door panel carries a full-range compatibility designation, meaning the specified driver type is expected to reproduce the entire audible frequency spectrum from lows through highs from a single driver unit.
Full-range speakers incorporate a main woofer cone alongside a smaller whizzer cone or integrated tweeter element, allowing a single driver to handle both low-frequency body and high-frequency detail within the rear door panel space.
In a rear door panel context, a full-range 6x9 inch driver handles midbass frequencies - roughly 80 Hz to 500 Hz - with particular authority due to cone area, making door panel placement acoustically suited for reinforcing the lower-midrange content of music.
The high-frequency reproduction of a full-range 6x9 inch unit is limited compared to a dedicated tweeter; the rear door panel location, being physically distant from the listener's ears relative to front-mounted drivers, means high-frequency roll-off at this position has a reduced impact on perceived imaging.
The Dodge Dart rear door panel maintains the 6x9 inch full-range specification consistently across the 2013, 2014, 2015, and 2016 model years, indicating dimensional and mounting uniformity in the rear door cavity across all 4 of those production years.
Door panel speaker mounting typically uses a stamped metal or plastic bracket integrated into the door, and 6x9 inch drivers require an oval cutout with a mounting flange pattern that must align with the factory bracket to achieve a flush, rattle-free fit.
