Additional Notes
- The front door panel speakers in the 1991 Plymouth Sundance measure 5.25 inches, which suggests they were designed as either midbass drivers or full-range units depending on the factory configuration, allowing owners to choose between dedicated frequency reproduction or broader audio coverage when selecting replacements.
- Rear door panel positions accommodate 5x7 inch full-range speakers, a size that was commonly used in entry-level domestic vehicles during the early 1990s because the oval format allowed manufacturers to maximize cone area within constrained door panel geometry while keeping production costs manageable.
- The single DIN radio mounting space indicates standard head unit compatibility, meaning aftermarket stereo installations would not require additional dash modification or adapter kits beyond basic wiring harnesses specific to Chrysler products from this era.
- Speaker replacement in the 1991 Plymouth Sundance would likely prioritize the rear door positions if sound quality improvement is the goal, since the larger 5x7 inch format typically provides better mid-range frequency response and higher sensitivity ratings compared to the smaller 5.25 inch front units, though this assumes the rear speakers receive adequate amplification.
- Full-range speaker types are specified for both front and rear positions, indicating the factory audio system probably operated without separate tweeters or component crossover networks, which was typical of base-trim audio packages in domestic vehicles during this production period.
- The 5.25 inch front speaker size offers reasonable compatibility with contemporary aftermarket options, as this remains a standard format among speaker manufacturers, though owners may need to verify mounting depth clearance within the door panels before installation to avoid interference with window mechanisms or interior trim panels.
