Additional Notes

  • The 1991 Plymouth Grand Voyager positions full-range speakers in both front and door panel locations, suggesting that these factory installations handle the entire frequency spectrum without separate tweeters or dedicated mid-range units in those positions.
  • Factory speaker replacement in this configuration may prioritize door panel locations since both front and rear positions accommodate 6x9 inch openings, potentially allowing for upgrades with higher power handling and improved frequency response characteristics.
  • Full-range speaker types in oval form typically offer advantages in vocal clarity and mid-frequency reproduction when compared to smaller round speakers, though aftermarket options with polypropylene or treated paper cones could provide enhanced bass response within the same mounting footprint.
  • The uniform 6x9 inch sizing throughout the door panels of the 1991 Plymouth Grand Voyager could simplify component matching if someone considers upgrading multiple speaker locations simultaneously with identical aftermarket models.
  • Sound improvement potential in this speaker layout may come from aftermarket full-range speakers featuring higher sensitivity ratings, which could increase output levels without requiring additional amplification beyond the factory head unit.
