Additional Notes

  • The 1991 Dodge D/W Series Pickups carries two distinct speaker locations, each with different sizing requirements, which may suggest that replacement priority could vary depending on which position shows wear or degradation first.
  • The behind-seat position calls for a 4x10 inch full-range driver, a less common sizing that could potentially limit the number of compatible aftermarket options available on the market.
  • The front door panel position accommodates a 6x9 inch full-range speaker, a sizing that tends to have wider aftermarket support and may allow for more cone surface area relative to the behind-seat unit.
  • Both positions are listed as full-range compatible types, which could indicate that each location is intended to handle the full audio frequency spectrum independently, rather than relying on a dedicated multi-component setup.
  • The size difference between the two positions suggests that the front door panel speakers may offer a broader low-frequency response due to their larger overall surface area compared to the behind-seat units.
  • Since both locations use full-range drivers, any noticeable improvement in audio output would likely depend on the sensitivity rating and frequency response characteristics of the replacement units selected for each position.
