Additional Notes
- The 1985 Dodge Diplomat dashboard positions accommodate 3.5-inch full-range speakers, which represent the smaller factory locations in this configuration and may be considered secondary to the larger rear positions when planning an audio upgrade sequence.
- Full-range speakers in the 3.5-inch size typically handle mid and high frequencies more effectively than lower bass response, which positions them as complementary components to the rear deck speakers in the overall sound staging.
- The rear deck lid positions accept 6x9-inch full-range speakers, which offer larger cone area compared to the dashboard locations and generally provide improved bass output and overall volume capacity within the cabin space.
- The 6x9-inch format provides an oval speaker design that can move more air than circular speakers of equivalent width, potentially delivering fuller low-frequency reproduction without requiring separate subwoofer components for casual listening applications.
- Factory speaker replacement in this configuration tends to show the most noticeable sonic improvement when addressing the rear deck positions first, as the larger surface area and mounting location contribute more substantially to overall sound pressure levels.
- The single DIN radio opening allows for aftermarket head unit installation, which can provide increased power output to drive replacement speakers more effectively than the original equipment amplification.
- Both speaker locations specify full-range compatibility, indicating these positions were designed to handle the complete frequency spectrum without dedicated tweeters or mid-bass drivers in separate mounting points.
- The combination of smaller dashboard and larger rear speakers creates a sound field where high frequencies emanate from the front while the rear deck provides the foundation for mid-bass and lower frequencies throughout the interior.
