- The rear deck lid positions in the 1979 Chevrolet Impala take a 6x9 inch speaker, which is a notably larger size than the 4x6 inch dashboard positions, suggesting the rear locations may carry more acoustic weight in an overall sound system setup.
- Both speaker positions are noted as compatible with full-range drivers only, meaning coaxial or similar full-range units would likely be the applicable choice for either location, with no indication of component or subwoofer compatibility in either position.
- A full-range driver handles low, mid, and high frequencies within a single unit, so the sound reproduction across both positions may rely entirely on each individual driver's ability to manage the full audible spectrum without dedicated tweeters or woofers.
- Given the size difference between the two positions, the 6x9 inch rear deck drivers would generally be associated with greater low-frequency output compared to the 4x6 inch dashboard units, which tend to favor midrange and high-frequency reproduction due to their smaller cone area.
- If only one set of positions were to be prioritized for replacement, the rear deck lid locations, with their larger 6x9 inch sizing, could potentially contribute more noticeably to overall sound output, particularly in the lower frequency range.
