Additional Notes

  • The 1998 Oldsmobile LSS front door panels accommodate 4x6 inch full-range speakers, which represent one of the smaller factory speaker sizes typically found in door locations during this era of automotive manufacturing.
  • Rear deck lid positions accept 6x9 inch full-range speakers, providing a larger surface area for sound reproduction compared to the front speakers and potentially contributing to lower frequency output.
  • Both speaker locations utilize full-range designs rather than component systems, meaning single speakers handle the entire frequency spectrum without separate tweeters or crossovers in the factory configuration.
  • The size difference between front and rear speakers suggests that upgrading the rear deck speakers might yield more noticeable bass response improvements due to the larger cone area available in 6x9 inch units.
  • Aftermarket speaker options for both locations would need to match these specific rectangular dimensions, as circular speakers would not fit the factory mounting openings without adapter brackets or modifications.
  • The radio opening supports both single DIN and double DIN head units, offering flexibility for audio source upgrades that could complement any speaker replacements.
