Additional Notes

  • The 1990 Chrysler Imperial uses dashboard speakers that accept 3.5 inch full-range drivers, which represent the smallest factory positions in this application and may benefit from aftermarket upgrades to enhance clarity in the mid-to-high frequency range.
  • Rear deck lid positions accommodate 5.25 inch drivers with compatibility for both midbass and full-range speaker types, offering flexibility in component selection based on whether dedicated bass reinforcement or broader frequency coverage is preferred.
  • The single DIN radio opening follows standard dimensions, which can facilitate head unit replacement when coordinating with speaker system upgrades.
  • Full-range speakers in the 3.5 inch dashboard locations handle the entire frequency spectrum within physical constraints, though their compact size inherently limits low-frequency extension and overall output capability.
  • The rear deck positions may provide more substantial sound improvement potential due to the larger 5.25 inch format, which generally produces stronger bass response and higher sensitivity compared to dashboard units.
  • Midbass-specific drivers in the rear deck could work in conjunction with separate tweeters or dashboard speakers to create a distributed frequency response throughout the cabin.
  • The combination of 3.5 inch and 5.25 inch factory sizes suggests a front-to-rear staging design where dashboard speakers handle localization cues while rear speakers contribute ambience and low-frequency support.
