Additional Notes
- The 2009 Mercedes-Benz GL320 contains a mixed speaker configuration with tweeters at 1 inch, mid-range drivers at 6.5 inches, a center unit at 3.5 inches, and a cargo-mounted subwoofer at 8 inches.
- Tweeters occupy three distinct locations throughout the cabin, suggesting a multi-point high-frequency distribution system rather than a conventional two-way setup.
- The 6.5 inch door speakers accept both midbass and full-range types, which may indicate flexibility in component versus coaxial speaker selection during replacement.
- Front door panels house both 1 inch tweeters and 6.5 inch drivers, pointing toward a factory component speaker design that separates frequency ranges between dedicated units.
- The center dash position utilizes a 3.5 inch full-range speaker, likely serving dialog or center channel duties in what could be a surround-configured audio system.
- An 8 inch subwoofer in the cargo area handles low-frequency reproduction, which is relatively compact compared to aftermarket solutions but typical for factory installations where space efficiency matters.
- Rear door panels mirror the front configuration with both 1 inch tweeters and 6.5 inch midbass or full-range options, maintaining consistent staging from front to rear.
- The rear roof tweeter placement may contribute to ambient soundstage or serve third-row passengers, depending on the specific audio system variant installed.
- Replacing the 6.5 inch door speakers would likely produce the most noticeable improvement in midrange clarity and vocal reproduction given their size and location.
- The radio accepts both single and double DIN configurations, providing flexibility for head unit upgrades that might better drive aftermarket speaker replacements.
