Additional Notes

  • The 1990 Chevrolet Caprice uses two different speaker sizes across its factory locations, with 4x6 inch units mounted in the dashboard and larger 6x9 inch speakers positioned in the rear deck lid.
  • Both speaker locations accommodate full-range drivers, which handle the entire frequency spectrum from bass through treble without requiring separate woofers or tweeters.
  • The rear deck lid speakers typically receive replacement priority due to their larger 6x9 inch size, which generally provides greater sound output and improved bass response compared to the smaller dashboard units.
  • Full-range speakers in these sizes often feature integrated whizzer cones or coaxial designs that attempt to reproduce high frequencies while the main cone handles midrange and lower frequencies.
  • The single DIN radio opening allows for straightforward head unit replacement without requiring mounting adapters or dash modifications beyond standard installation brackets.
  • Aftermarket 6x9 inch speakers frequently offer power handling capabilities between 50 and 100 watts RMS, potentially providing noticeable sonic improvements over factory-installed components from this era.
  • The 4x6 inch dashboard speakers may benefit from replacement with modern equivalents featuring better materials such as polypropylene cones and rubber surrounds rather than the paper components common in period-correct factory speakers.
  • Installing upgraded full-range speakers in both locations could enhance clarity and volume without requiring amplification, though adding an external amplifier would further maximize the potential of higher-quality replacement speakers.
