- The dashboard location in the 1986 Chevrolet Blazer uses a 3.5 inch full-range speaker, which suggests it may be the higher-priority replacement position given its placement in the primary listening plane relative to the occupants.
- A full-range driver at the dashboard position would likely handle the entire audible frequency spectrum on its own, which could mean there is no separate provision for a dedicated tweeter or woofer in that location.
- The rear door panel accommodates a 4x10 inch oval full-range speaker, a format that tends to offer a larger cone surface area than a standard round driver of comparable sizing, which may contribute to somewhat greater low-frequency output from that position.
- Both locations appear to rely solely on full-range drivers, suggesting the factory configuration was not designed around a component speaker setup with dedicated crossover networks.
- Replacing the rear door panel speakers with aftermarket 4x10 inch full-range units could potentially broaden the overall soundstage, though the extent of any improvement would likely depend on the quality of the replacement drivers selected.
