Additional Notes

  • The dashboard location in the 1979 GMC C/K Series 3500 appears to be fitted with a relatively small 3.5 inch opening, which may suggest that replacement options could be somewhat limited compared to larger speaker positions in the vehicle.
  • The dashboard position is noted as compatible with full-range speaker types, which tend to handle a broader frequency spectrum within a single driver unit, potentially covering highs and mids without requiring additional components.
  • The rear door panel position accommodates a 4x10 inch oval speaker configuration, which is a notably larger form factor than the dashboard location and may suggest a greater capacity for lower frequency reproduction relative to the front.
  • The rear door panel also lists full-range compatibility, meaning both positions in this vehicle could theoretically be served by the same driver type, though the size difference between the two locations might influence overall frequency balance.
  • Given the size disparity between the 3.5 inch dashboard and the 4x10 inch rear door panel, the rear door panel location could be considered the higher priority replacement point for those seeking a more noticeable shift in audio output.
