What size speakers are in a 1988 Chevy S10?
The standard 1988 Chevy S-10 typically uses two 4x6 inch speakers in the front doors. If you have an extended-cab model or a version with rear speakers, additional speakers in the back can vary, commonly 4x6 inches or 6x9 inches depending on the option package and market. Verify the exact configuration on your truck if precision is required for replacement.
Understanding the stock setup by cab configuration
Two-door standard cab
In the typical two-door S-10 from 1988, the front-door speakers are most often 4x6 inches. This setup relied on the door-mounted speakers for the primary listening experience, with optional rear speakers not always included in base trims.
Extended cab and rear speaker options
Extended-cab models introduced space for rear seating and additional speakers. The size of these rear speakers varied by package and market, with common possibilities including 4x6 inches or 6x9 inches mounted in rear locations. Exact sizes depend on the specific build sheet or dealer option codes for your truck.
How to confirm the exact size for your vehicle
To determine the precise speaker sizes for your specific 1988 S-10, inspect the mounting locations by removing a door panel or rear cover to measure the speaker opening, or consult the factory build sheet and service manual for your VIN. If you’re planning a replacement and the exact size isn’t clear, aftermarket adapters and common 4x6 or 6x9 replacements can often be made to fit with appropriate mounting hardware.
Summary
For most 1988 Chevy S-10 trucks, front-door speakers are 4x6 inches. Extended-cab or rear-speaker configurations may use 4x6 or 6x9 inch speakers depending on the option package. Always verify on the specific vehicle via inspection or by checking the original build documentation to ensure you select the correct replacement sizes.
