Additional Notes

  • The 2002 Pontiac Bonneville utilizes three different speaker sizes across its audio system, with the front door panels accommodating the largest round speakers at 6.5 inches, while the rear doors feature smaller 5.25-inch units.
  • Front door speakers may be prioritized for replacement given their larger size and potential for greater sound reproduction capabilities compared to the rear door installations.
  • Both door-mounted speakers accept midbass or full-range driver types, which could allow for different installation approaches depending on whether the factory system includes separate tweeters.
  • The rear deck lid houses 6x9-inch oval speakers designated for full-range operation, which typically handle a broader frequency spectrum than the door-mounted units when configured as such.
  • Full-range speakers in the rear deck position may contribute to rear fill and overall sound staging within the cabin, though their effectiveness varies based on listener position.
  • The radio opening supports both single DIN and double DIN head units, providing flexibility for aftermarket audio source upgrades that might better drive replacement speakers.
  • Upgrading to aftermarket midbass drivers in the door locations could enhance lower frequency response, particularly if paired with component system tweeters installed separately.
  • The different speaker sizes suggest a factory tuning approach that distributed frequency responsibilities across multiple locations rather than relying on identical drivers throughout.
