- The front and rear door panels of the 2018 Mazda CX-3 share the same 6.75-inch speaker size, which may suggest that the same replacement driver could potentially work across all four door locations.
- The door panel positions are listed as compatible with midbass or full-range speaker types, meaning they could handle a broader portion of the audible frequency spectrum compared to the other locations in the vehicle.
- The dashboard position accommodates a 1-inch tweeter, a driver type generally associated with high-frequency reproduction, which may contribute to upper-range clarity when paired with the door-mounted drivers.
- The cargo area supports a 5.25-inch subwoofer, a placement that tends to be less than ideal acoustically due to its distance from the main listening positions, though the low-frequency output of a subwoofer is generally less directional by nature.
- Given that the door panel locations represent the largest drivers and cover the widest frequency range, they could reasonably be considered the higher-priority positions when addressing audio output quality.
- The existing tweeter and subwoofer placements suggest the factory audio system may have been designed with some degree of frequency division in mind, separating high-frequency and low-frequency reproduction across distinct locations.
