How to verify the exact size on your vehicle
To confirm the precise speaker size for your truck, follow these steps.
- Park safely and disconnect the battery if you’re going to remove panels for inspection.
- Remove the front door panel to access the 6.5-inch speaker mounting area and measure the mounting diameter if needed.
- Inspect the rear door panels for the 4x6-inch speaker mounting holes or check the side panels behind the rear seats for any 6x9 speakers if you have a premium setup.
- Check the vehicle’s description label or service manual for the original equipment information or consult a Chevy dealer for the exact spec.
Verifying the exact sizes ensures you select compatible aftermarket replacements and avoid fitment issues.
Replacement considerations
When upgrading, the standard and most common replacements are:
- Front door: 6.5-inch coaxial or component speakers.
- Rear doors: 4x6-inch speakers on most extended-cab models.
- Premium systems: follow the manufacturer’s recommended sizes for any 6x9 rear speakers or equivalent configurations.
In all cases, confirm the size by measuring or consulting documentation specific to your truck’s audio package, as configurations can vary by production date and trim level.
Summary: For a typical 2003 Chevy Silverado Extended Cab, expect 6.5-inch front-door speakers and 4x6-inch rear-door speakers, with possible variations to 6x9-inch rear speakers on premium audio packages. Always verify on your vehicle for exact fitment before purchasing replacements.
