- The front and rear door panels of the 2018 Nissan March share the same 6.5 inch sizing, which may suggest that a consistent speaker type could be used across both door locations without requiring different mounting hardware or adapters.
- The A-pillar position appears to be sized for a 1 inch tweeter, which is a relatively small high-frequency driver typically suited for reproducing upper-range frequencies rather than handling a wider sonic spectrum.
- The door panel locations list compatibility with both midbass and full-range speaker types, which could indicate some flexibility in how the low-to-mid frequency response is handled, depending on whether a full-range or a dedicated midbass driver is installed.
- Given that the A-pillar houses only a tweeter-sized slot, any meaningful improvement in overall sound quality would likely depend on pairing that position with adequately capable midbass or full-range drivers in the door panels to cover the frequencies the tweeter alone would not reproduce.
- The separation of tweeter placement at the A-pillar from the larger door panel positions might suggest a factory layout that somewhat favors a component-style speaker arrangement, where high and low frequencies are handled by physically separate drivers.
