What size speakers are in the back door of a 2000 Chevy Silverado?
The rear-door speakers on most 2000 Chevy Silverado pickups are 4x6 inches. This size is standard for the era and cab configurations, though exact setups can vary with specific trim levels or aftermarket changes. Use the guidance below to confirm the exact size on your truck and plan replacements accordingly.
Typical rear-door speaker size
Most 2000 Silverado models with either regular or extended cabs use 4x6 inch speakers in the rear doors. These are typically two-way coaxial units that fit the standard mounting pattern for GM trucks of that generation.
- 4x6 inches (approximately 101.6 mm x 152.4 mm) two-way rear-door speakers are standard for the majority of 2000 Silverado configurations.
Variations can occur if the vehicle has a rare factory premium system or aftermarket modifications, so it’s wise to verify on your exact truck if you’re planning a replacement.
How to confirm the exact size on your truck
To ensure you buy the correct replacement, verify the exact rear-door speaker size on your specific vehicle by following these steps.
- Open the rear door and remove the speaker grille to access the speaker. Look for any size markings or a model number on the speaker itself.
- If the speaker is missing or inaccessible, measure the mounting opening: measure the diameter of the circular cutout and note the mounting hole pattern. A 4x6 inch speaker typically requires about a 4-inch inner opening with four mounting holes arranged accordingly.
- Compare your measurements to common sizes (4x6, 5.25, 6.5) to narrow down the likely option.
- Check the vehicle’s service manual or a VIN-specific OEM parts catalog to confirm the exact speaker size for your trim and door configuration.
- If replacing, consider bringing the current speaker to an auto parts store or consulting the dealer to ensure compatibility, especially if premium audio equipment is installed.
Note: Some rare or dealer-installed premium audio packages may use non-standard sizes or configurations. When in doubt, verify with documentation or a parts specialist for your exact vehicle.
Additional considerations for aftermarket or premium audio
For vehicles equipped with certain factory premium systems, the rear speakers might differ from the standard 4x6 size. If your Silverado has a Bose or other premium setup, consult the original equipment documentation or a professional installer to confirm the correct speaker dimensions and mounting requirements.
Summary
On a 2000 Chevy Silverado, the back-door speakers are typically 4x6 inches, matching the common configuration for that era and cab styles. To be certain, verify by inspecting the door panel, measuring the mounting opening, or consulting OEM documentation. This will help you select the right replacement and maintain proper fit and sound quality.
