Additional Notes
- The 2011 Mercedes-Benz C350 features a multi-speaker configuration with tweeters positioned in the front door panels, rear door panels, and rear deck center, all at 1 inch sizing.
- Front and rear door panels each contain both a 1 inch tweeter and a 6.5 inch midbass or full-range speaker, suggesting a component-style factory audio setup in these locations.
- The center dash houses a 3.5 inch full-range speaker, which typically handles mid-frequency reproduction in factory audio systems.
- An 8 inch subwoofer location exists in the rear deck center position, alongside the 1 inch tweeter at that same general location.
- Upgrading the 6.5 inch door speakers may provide noticeable improvements in midrange clarity and overall sound quality, as these handle the bulk of the frequency spectrum in typical listening conditions.
- The tweeter positions could accept aftermarket 1 inch dome tweeters if component speaker installations are planned, though factory integration at this size may require mounting adapters.
- The rear deck center subwoofer at 8 inches represents a relatively modest bass driver size, leaving potential for enhanced low-frequency output through aftermarket replacement or supplemental subwoofer additions.
- The double DIN radio opening allows for installation of modern head units with expanded features and amplification capabilities to support upgraded speaker components.
