Additional Notes
- The 1998 Lexus GS400 features three distinct speaker locations with varying sizes and functional capabilities throughout the cabin.
- Factory speakers in the door panels measure 6.5 inches across all four locations, indicating a symmetrical front-to-rear configuration.
- Door-mounted speakers accept both midbass and full-range driver types, offering flexibility in component selection based on system design preferences.
- The rear deck lid accommodates a 10-inch driver specifically designed for subwoofer applications, suggesting factory bass reinforcement capability.
- Midbass drivers typically handle frequencies between approximately 80Hz and 500Hz, while full-range speakers attempt to reproduce a broader spectrum from bass through treble.
- Component systems using dedicated midbass drivers in the doors would require separate tweeters and crossovers for high-frequency reproduction.
- Full-range speakers provide a simpler replacement option without additional components, though they may sacrifice some frequency response accuracy.
- The 10-inch rear deck location suggests potential for noticeable low-frequency output improvement with an aftermarket subwoofer installation.
- Subwoofer upgrades often yield the most perceptible sound quality gains in factory audio systems, as OEM bass drivers tend to have limited excursion capabilities.
- The radio opening accepts both single DIN and double DIN head units, providing options for modern source unit integration with updated connectivity features.
