Additional Notes

  • The 1987 Chevrolet Astro utilizes two distinct speaker locations with different size requirements, suggesting that prioritizing dashboard replacement over rear door panels may provide more substantial sound improvement due to the larger 6x9 inch opening and front-stage positioning.
  • Full-range speakers are compatible with both locations, indicating that a complete system upgrade could be achieved without requiring separate component sets or additional crossovers for frequency management.
  • The 6.5 inch rear door panel position accepts midbass drivers as an alternative to full-range units, which could allow for a more specialized configuration where dedicated midbass handles lower frequencies while dashboard speakers manage mid and high frequencies.
  • Dashboard mounting typically places speakers higher in the soundstage compared to door panels, potentially creating better stereo imaging when combined with the larger 6x9 format's improved midrange response.
  • The single DIN radio opening limits head unit selection to standard-height models, though this format remains widely available and often costs less than double DIN alternatives while providing adequate power output for aftermarket speaker upgrades.
