Additional Notes

  • The rear door panel locations in the 2002 GMC C/K Series 3500 take a 6.75 inch driver, which is a notably larger format than the 5.25 inch front door panel fitment. This size difference may suggest that the rear positions could handle somewhat greater low-frequency output by nature of the larger cone area.
  • Both the front and rear door panel positions share the same compatible driver types, supporting either midbass or full-range configurations. A midbass driver would typically be paired with a separate tweeter in a component system arrangement, while a full-range driver would handle the entire audible spectrum from a single unit.
  • Given that the rear door panel accommodates a 6.75 inch driver, that position could be considered a relatively higher priority for replacement when low-frequency extension and output level are among the primary concerns in a system build.
  • The front door panel positions, rated for 5.25 inch drivers, might be more naturally suited to full-range operation or use within a component setup, where a dedicated tweeter handles high-frequency reproduction and the midbass driver covers the lower portion of the spectrum.
