Additional Notes

  • The 1966 Chevrolet Impala carries two speaker locations, with the center dash position likely being the more acoustically limited of the two due to its 4x10 inch sizing, which may restrict low-frequency reproduction compared to the larger rear deck lid position.
  • Both locations are listed as compatible with full-range speaker types only, suggesting that component speaker systems with separate tweeters and woofers may not be a straightforward fit for either position.
  • The rear deck lid's 6x9 inch specification tends to support a wider frequency response and greater cone surface area, which could translate to a more noticeable improvement in overall sound output relative to the center dash location.
  • Given the size difference between the two positions, a replacement prioritization toward the rear deck lid's 6x9 inch slot may yield more audible gains, as larger cone surface area generally correlates with improved bass response and overall volume.
  • Full-range drivers for the 4x10 inch center dash position might be somewhat harder to source in modern aftermarket offerings, as this size is less common than the 6x9 inch format found at the rear.
