Additional Notes
- The dashboard speaker positions in the 1991 Eagle Summit accept 4-inch midrange units, which suggests these locations were designed to handle the middle frequencies of the audio spectrum rather than serving as full-range drivers. This separation of frequency ranges across different speaker locations indicates a multi-speaker approach to cabin audio distribution.
- Rear door panel locations accommodate 6x9 inch full-range speakers, which typically provide broader frequency coverage than midrange units. The oval footprint of these speakers allows for a larger cone area within the available mounting space, potentially contributing to enhanced low-frequency output compared to smaller circular drivers.
- The single DIN radio specification defines the head unit opening size as approximately 7 inches wide by 2 inches tall. This standardized format was common during the early 1990s and determines compatibility with aftermarket stereo receivers, which must conform to these dimensional constraints.
- Replacing the rear door panel speakers might take precedence over dashboard units when considering sound quality improvements, as the 6x9 inch full-range configuration provides broader frequency response capabilities. The larger surface area and full-range design of the 1991 Eagle Summit rear speakers could offer more noticeable enhancements to overall audio performance.
- The midrange designation for dashboard speakers indicates they were likely intended to reproduce vocal frequencies and instrumental midrange content, working in conjunction with the rear full-range units to create a distributed soundstage. This configuration suggests that bass reproduction duties would fall primarily to the rear door speakers.
- Aftermarket speaker selection for the rear positions would benefit from considering sensitivity ratings and power handling characteristics that match the factory radio output. Full-range speakers in this size category often feature integrated tweeters or whizzer cones to extend high-frequency response beyond what the cone material alone could achieve.
