- The dashboard position in the 1983 GMC C/K Series 3500 uses a 3.5-inch full-range speaker, which suggests it may handle the entire audible frequency spectrum on its own, without a separate tweeter or woofer to supplement it.
- The rear door panel position appears to accommodate a 4x10-inch oval full-range speaker, a less common sizing that could limit the pool of compatible aftermarket options compared to more standard configurations.
- Given that full-range speakers cover the whole frequency spectrum, replacing either position with a component speaker system may not be directly compatible without additional mounting modifications.
- The rear door panel's 4x10-inch oval sizing tends to produce a wider soundstage than smaller round alternatives, which could suggest a marginal improvement in mid-bass response when upgraded to a higher-quality full-range unit of the same size.
- Between the two positions, the rear door panel may be considered a higher-priority replacement given that larger speaker surfaces generally have a more noticeable impact on overall cabin sound output than the smaller dashboard unit.
