- The dashboard position in the 1980 GMC C/K Series 3500 uses a 3.5 inch full-range driver, which is a relatively small form factor that may limit low-frequency output and overall acoustic range compared to larger aftermarket options.
- A full-range driver handles the entire audible frequency spectrum within a single cone unit, so both the dashboard and rear door panel positions rely on this design without the benefit of dedicated woofer or tweeter components.
- The rear door panel accommodates a 4x10 inch oval full-range speaker, an elongated form factor that tends to offer a broader radiating surface area than a standard round unit of similar width, which could contribute to improved bass response relative to the dashboard placement.
- Given the size difference between the two positions, the rear door panel location may be considered the higher priority replacement point, as the larger 4x10 inch driver would likely have a more noticeable effect on overall sound output.
- The absence of dedicated tweeters or component speaker configurations in these positions suggests that any meaningful improvement in high-frequency clarity would depend on the frequency response characteristics of whichever full-range replacement driver is selected.
