- The rear roof location in the 2003 Chevrolet Express takes a 4x6 inch speaker, which is a relatively modest oval size that may limit low-frequency output compared to the larger positions elsewhere in the vehicle.
- The front door panel position accommodates a 6.75 inch round speaker, which is a somewhat uncommon size that could narrow the range of compatible aftermarket options available for that location.
- A midbass driver in the front door panel position may allow for better lower-midrange and upper-bass reproduction than a standard full-range unit, which could be worth considering depending on listening preferences.
- The rear cargo area doors hold a 6x9 inch oval speaker, generally one of the larger standard sizes in automotive audio, which tends to support stronger low-frequency output relative to smaller positions.
- Given the size and typical frequency handling associated with the 6x9 inch position, the rear cargo area doors may represent a higher priority location for replacement if improved bass presence is a goal.
- The front door panel location, being the closest speaker position to the listening area, may have a notable influence on midrange clarity and overall perceived sound quality relative to the rear positions.
