Additional Notes

  • The overhead position in the 2023 GMC Savana takes a 4x6 inch speaker, which is limited to full-range compatibility only, suggesting it may be a lower priority replacement compared to positions that support a wider variety of driver types.
  • The front door panel position accommodates a 6.75 inch speaker and supports both midbass and full-range types, which could allow for a more defined low-to-mid frequency reproduction than the overhead position, potentially making it a worthwhile candidate for priority replacement.
  • A midbass driver in the front door panel position would handle frequencies in the lower midrange band without the need for a full-range unit, which may suit configurations where a separate tweeter is already present or planned.
  • The rear cargo area door position fits a 6x9 inch speaker, a size generally associated with broader cone surface area that may contribute to greater low-frequency output relative to the smaller positions in the vehicle.
  • Full-range drivers across all three positions would likely provide a baseline improvement over factory speakers, though the front door panel and rear cargo positions, given their larger sizing, may yield more noticeable changes in overall sound output.
