- The dashboard position in the 1987 Toyota 4Runner accommodates 4-inch midrange speakers, which typically handle frequencies in the vocal and instrumental range rather than providing bass response.
- Front door panel locations accept 5.25-inch speakers that can function as either midbass drivers or full-range units, offering flexibility in system configuration depending on whether a separate subwoofer is present.
- Rear side panel positions mirror the front door specifications with 5.25-inch compatibility, allowing for matched speaker sets throughout the cabin if desired.
- The smaller dashboard speakers may benefit from replacement first when addressing sound degradation, as midrange drivers in this position often deteriorate due to sun exposure and temperature fluctuations.
- Full-range speakers in the door and rear positions would provide broader frequency coverage compared to dedicated midbass drivers, though the latter might integrate better with a component system including separate tweeters.
- The 5.25-inch size represents a common format that balances low-frequency output with physical constraints in door and panel installations.
- Component separation between the dashboard midrange units and larger door speakers could create a natural soundstage with higher frequencies emanating from the dash level while mid-bass content projects from lower mounting points.
- Aftermarket speaker selection for these locations would likely focus on sensitivity ratings, as factory amplification in vehicles from this era typically provided modest power output.
