- The rear deck lid positions in the 1978 Chevrolet Malibu may represent a higher priority for replacement, as the 6x9 inch openings tend to accommodate drivers with greater cone surface area, which could translate to a more noticeable shift in low-frequency output compared to the smaller dashboard locations.
- The 3.5 inch dashboard openings are sized to fit full-range drivers, meaning a single driver at each location would handle the entire audible frequency spectrum without a dedicated crossover network.
- The 6x9 inch rear deck lid positions also support full-range driver configurations, and the larger footprint of those drivers may allow for somewhat extended bass response relative to what the 3.5 inch dashboard units could reasonably produce.
- Since both locations are rated for full-range compatibility only, there is no indication from the specifications that component sets or separate tweeter installations were factory-supported in either position.
