Additional Notes
- The 1990 Toyota Celica factory audio configuration includes four different speaker locations with varying sizes, suggesting that replacing the front door speakers could yield the most substantial audio improvement due to their larger 6.5 inch size and positioning relative to the listener.
- Dashboard speakers are limited to 4 inch midrange drivers, which typically handle middle frequencies but lack the capability to reproduce deep bass tones or the highest treble frequencies that larger full-range speakers can deliver.
- Three of the four speaker positions accept midbass or full-range drivers, potentially allowing for bass response down to approximately 60-80 Hz depending on the specific aftermarket speakers selected and door panel acoustics.
- The rear door panels accommodate 5.25 inch speakers while the rear side panels take 6.5 inch units, creating a size mismatch in the rear soundstage that might benefit from careful component selection to maintain tonal balance.
- Both single DIN and double DIN head units fit the radio opening, providing flexibility for installing aftermarket receivers with built-in amplifiers that could drive upgraded speakers more effectively than the factory unit.
- Full-range speakers in the 6.5 inch positions would handle frequencies from bass through treble without requiring separate tweeters, though component speaker systems with dedicated tweeters might offer better high-frequency dispersion.
- The dashboard midrange speakers likely crossed over at higher frequencies in the factory setup, working in conjunction with the larger door and panel speakers to create the intended frequency distribution.
