Additional Notes

  • The overhead position in the 2017 GMC Savana calls for a 4x6 inch speaker, which is generally considered a lower-priority location compared to the door panel and cargo area positions, given its placement away from primary listening zones.
  • The front door panel position takes a 6.75 inch speaker, a somewhat less common sizing that may require attention when sourcing compatible replacements, as fewer aftermarket options tend to be available at this size relative to more standard sizing.
  • The front door panel's compatibility with midbass speaker types suggests this position could potentially handle more focused low-to-mid frequency reproduction, which may contribute to a more structured sound stage in the forward cabin area.
  • The rear cargo area doors support a 6x9 inch format, which is generally associated with broader frequency response and higher power handling capacity among full-range driver types, possibly making this position relevant for overall low-frequency presence.
  • All three positions list full-range compatibility, suggesting the factory speaker layout may have relied on a relatively straightforward, non-dedicated driver setup across the vehicle.
  • Upgrading the front door panel position to a midbass-capable driver, as supported by its specifications, could potentially shift more tonal weight to the mid and lower-mid frequencies in the primary listening area.
