Additional Notes
- The 1987 Dodge Diplomat uses two different speaker sizes in its factory audio configuration, with smaller units positioned in the dashboard and larger oval speakers located in the rear deck lid area.
- Dashboard speakers at 3.5 inches represent relatively compact dimensions that may limit bass response capabilities compared to larger driver configurations, though full-range types can reproduce a broad frequency spectrum within physical constraints.
- Rear deck lid positions accommodate 6x9 inch speakers, which tend to offer greater surface area for moving air and potentially improved low-frequency output compared to smaller dashboard units.
- Full-range speaker compatibility across both locations suggests the factory system relied on individual drivers to reproduce all audible frequencies rather than employing dedicated tweeters or woofers in component arrangements.
- Replacing the rear deck speakers might yield more noticeable acoustic improvements than dashboard upgrades due to the larger cone area available in 6x9 inch formats.
- The single DIN radio opening follows standardized head unit dimensions, which allows for straightforward replacement with aftermarket receivers without requiring dash modification.
- Aftermarket 3.5 inch speakers often feature higher sensitivity ratings and improved materials compared to original equipment, which could enhance clarity in the upper frequency ranges from dashboard positions.
- The 6x9 inch format remains common in aftermarket speaker lines, providing numerous replacement options with varying power handling and efficiency specifications.
