What size speakers are in the Silverado extended cab?
In most Silverado extended cab pickups, the front door speakers are 6.5 inches in diameter, with rear-door sizes varying by year and trim. The exact specification for your truck depends on its generation and option packages, so a precise match requires year and model details.
The question spans several generations of the Chevrolet Silverado, including older extended-cab layouts and newer configurations that used different naming conventions. Speaker sizes and placements evolved with redesigns, and trims sometimes swapped out components. This article outlines typical configurations and provides steps to confirm the exact sizes for your vehicle.
Speaker sizes by component and generation
Below are typical sizes found in common Silverado extended-cab configurations. Use these as a guide and verify for your exact year and trim before purchasing replacements.
GMT800 and GMT900 eras (roughly 1999–2013)
Front-door speakers are commonly 6.5 inches in diameter. Rear-door and dash configurations vary by trim level and option packages; some models use smaller rear-door speakers (often around 4x6 inches) while others may ford toward 6.5 inches depending on the specific build. Dash components (tweeters/midrange) tend to be smaller than door speakers.
GMT K2XX era (roughly 2014–present)
Front-door speakers typically remain 6.5 inches in diameter. Rear-door sizes vary with trim and cab configuration; some extended-cab/crew-cab models use 4x6 inch rear speakers, while others may use different formats. Dash and upper-range components continue to be smaller speakers or tweeters, with mounting options that differ by trim level.
Note: These are general patterns. Exact sizes depend on the specific year, cab configuration (Extended Cab vs. Double Cab in later generations), and the factory audio package. For precise fitment, verify against your VIN, owner's manual, or OEM service data.
How to verify the exact sizes for your truck
Use a few straightforward methods to nail down the correct speaker sizes for your Silverado extended cab:
- Check the owner's manual or service manual: Look for the audio system specifications or speaker sizes per location.
- Inspect the factory speakers: Remove a door panel and measure the mounting diameter and depth, or read the label on the existing speaker for size and impedance.
- Consult OEM parts catalogs: Enter your VIN or year/model to retrieve the exact speaker part numbers and dimensions used in that configuration.
Once you have the exact sizes, you can shop with confidence for replacements or upgrade kits that match the mounting depth and impedance. If you share the year and trim of your Silverado extended cab, I can provide precise sizes for that specific configuration.
Summary
Speaker sizes in a Silverado extended cab are not universal; they depend on the generation and trim. In many models, front doors use 6.5-inch drivers, with rear doors varying between 4x6 and 6.5 inches depending on the build. Dash components are smaller and can differ by year and package. To get exact fitment, identify the exact year and trim, then verify against OEM specifications or by measuring the mounting openings.
Conclusion: For accurate replacement or upgrade planning, confirm your Silverado extended cab’s specific configuration (year, cab type, and audio package) and use those sizes as your target. If you provide those details, I’ll give you exact measurements for that configuration.
Summary: The precise speaker sizes hinge on year and trim; start with commonly used sizes (front doors around 6.5 inches) and verify with OEM sources or measurements for your specific truck.
