Additional Notes
- The 1986 Chevrolet Astro rear door panel positions may receive upgrades first, as midbass drivers or full-range speakers at 6.5 inches could address bass response limitations often associated with factory-installed components in these locations.
- Dashboard locations accommodate 6x9 inch full-range speakers, which typically provide broader frequency response compared to smaller round drivers due to the larger cone area available for mid-range and bass reproduction.
- Full-range speakers in either location would handle all frequencies without requiring additional tweeters or crossovers, potentially simplifying installation while maintaining single DIN radio compatibility.
- The 6x9 inch format in dashboard positions generally offers more surface area for sound projection compared to the 6.5 inch round speakers, which might influence staging and overall output levels.
- Midbass capability in rear door panels could complement full-range dashboard speakers by reinforcing lower frequencies, though the rear door location may reduce direct sound delivery to front passengers.
- Oval 6x9 speakers often incorporate dual voice coils or extended cone designs to maximize the non-circular mounting space, potentially offering different tonal characteristics than round alternatives.
