Additional Notes

  • The 1999 Plymouth Neon factory audio system contains three distinct speaker locations that may benefit from aftermarket replacement, with each position serving a different role in the overall sound staging.
  • Dashboard speakers at 3.5 inches represent the smallest openings in the system and are limited to full-range driver options, which typically handle mid and high frequencies but may lack low-frequency extension.
  • Front door panel locations accept 6.5 inch speakers and offer flexibility between midbass-focused drivers and full-range units, potentially allowing for improved bass response compared to the dashboard position.
  • The rear deck lid accommodates 6x9 inch speakers that could provide enhanced output and frequency range due to their larger surface area, though they are designated for full-range operation only.
  • Prioritizing the front door panel speakers in the 1999 Plymouth Neon might yield the most noticeable improvement, as this location typically contributes more directly to the listening position and offers greater driver size options.
  • Full-range speakers attempt to reproduce the entire frequency spectrum through a single cone, while midbass drivers focus on low-to-mid frequencies and generally require pairing with separate tweeters for complete coverage.
  • The rear deck position could complement front speaker upgrades by adding fill and depth to the sound field, though front staging tends to be prioritized in automotive audio applications.
  • Component speaker systems might be considered for the front doors if tweeters can be mounted separately, as this configuration often provides better frequency separation than full-range alternatives.
