Additional Notes

  • The rear cargo area doors of the 2011 Chevrolet Express may represent a higher replacement priority, as the 6x9 inch full-range drivers positioned there could have a more direct influence on overall cabin audio coverage compared to the other locations.
  • The front door panel locations are sized at 6.75 inch and listed as compatible with midbass drivers, which suggests those positions may be capable of handling more focused low-to-mid frequency reproduction rather than being limited to full-range operation alone.
  • The rear roof location accommodates a 4x6 inch full-range driver, which is a relatively modest cone area and could potentially limit the low-frequency output that position is able to contribute to the listening space.
  • The presence of a midbass-compatible position at the front door panels may indicate that a two-way or component-style approach to speaker placement could be a consideration worth noting across the front stage.
  • With three distinct speaker locations spanning the front doors, rear roof, and rear cargo doors, the factory layout appears to distribute sound sources across a fairly wide range of positions throughout the vehicle interior.
