What size speakers are in the rear door of a Subaru Impreza?
The rear doors on most Subaru Impreza models use 6.5-inch speakers (165 mm) in diameter.
This size is standard across many recent generations for both sedan and hatchback bodies, though there can be exceptions depending on the year, trim level, or audio package. To be sure, check your owner's manual, inspect the mounting opening, or consult OEM parts diagrams for your exact model year.
Typical size and installation notes
In modern Impreza models, the rear-door speaker diameter is generally 6.5 inches (165 mm). This diameter is commonly used for both left and right rear doors, regardless of whether the car is equipped with the base audio system or an upgraded package. While the mounting hole size and depth can vary slightly by year or trim, the overall diameter remains 6.5 inches in the vast majority of cases.
Why size consistency matters
Correctly identifying the speaker size is important for choosing a replacement that fits the mounting opening, depth, and wiring harness. Using the wrong size can lead to fit issues, clearance problems, or improper seal, which can affect both sound quality and vehicle installation.
To confirm the exact rear-door speaker size for your specific Impreza, follow these steps:
- Consult the owner's manual or Subaru's official parts diagrams to verify the speaker size by model year and trim.
- Remove the rear door panel to expose the speaker, then measure the mounting hole diameter and available mounting depth.
- Look for a part number on the existing speaker or in the door cavity and cross-reference it with official diagrams or dealer databases.
- If you have access to a dealer or VIN-specific parts lookup, provide your VIN to confirm the precise size and correct replacement parts.
Following these steps will help ensure you select the correct 6.5-inch rear-door speaker or verify any potential model-specific deviations for your Impreza.
Summary
For most Subaru Impreza models, rear-door speakers are 6.5 inches (165 mm) in diameter. While this is the common standard across recent years and trims, always verify with model-year-specific documentation or a VIN-based parts lookup to account for any exceptions and ensure a proper fit when repairing or upgrading your audio system.
