Typical rear speaker size for the Focus MK2
The Ford Focus MK2 (2005–2011) generally uses a rectangular 6x4 inch rear-door speaker opening. This size refers to the mounting pattern, not the exact cone diameter, which is commonly about 4 inches on a 6x4 inch unit. While this is the standard for most trims and regions, rare variations can occur depending on the specific vehicle configuration.
Common sizes and fitment considerations
Most aftermarket and OEM replacements for the Focus MK2 rear doors are sold as 6x4 inch speakers. Some markets or late-production runs may present non-standard shapes or adapters, so confirm the fit before buying.
- 6x4 inch rectangular mounting pattern (standard for the majority of MK2 rear doors)
- Occasional deviations in rare market-specific builds, which may require measurement or adapters
For reliable results, treat 6x4 inches as the baseline and verify against your vehicle’s exact cutout or OEM part numbers.
How to verify the exact size in your car
Use these steps to confirm the precise rear speaker size for your Ford Focus MK2, since an exact fit is essential for proper audio performance.
- Remove the rear door panel to expose the speaker and mounting opening.
- Measure the cutout: width and height of the mounting rectangle and note any screw hole spacing.
- Check the vehicle’s VIN or service manual for the OEM speaker size specified for your exact model year and market.
- If in doubt, bring a photo of the opening or consult a parts catalog that lists 6x4 inch rear speakers for the Focus MK2.
These verification steps help ensure you select a replacement that fits without requiring uncommon adapters or modifications.
Replacement considerations
When shopping for replacements, most rear speakers for the Focus MK2 are offered as 6x4 inch coaxial units. Pay attention to mounting depth, power rating, and impedance to ensure compatibility with your head unit or amplifier. If you choose a component set or a larger woofer, you may need mounting spacers or adapters to achieve a proper fit.
Summary
