What size speakers are in a 2003 Chevy S10 LS?
Most 2003 S-10 LS pickups use 6.5-inch front door speakers; extended-cab models add 4x6 rear speakers, while regular-cab models typically have only front speakers.
Cab configuration and speaker layout
The 2003 Chevy S-10 LS lineup includes variations by cab style (regular cab vs. extended cab) which affects where speakers are located and what sizes fit. Below is a concise guide to the typical factory sizes by configuration.
Regular cab LS
In regular cab models, the standard setup centers on the front doors. The typical factory speaker size is 6.5 inches in the front doors, designed as a two-way unit. There are generally no rear speakers in this configuration, since there is no rear cabin space behind the seats.
Below is a quick reference of the regular cab configuration:
- Front door speakers: 6.5 inches (165 mm), typically a two‑way design.
- Rear speakers: none (regular cab layouts omit rear enclosures).
Concluding for regular cab LS: you should expect 6.5" front speakers and no rear speakers from the factory, though radios and trims can vary by option package.
Extended cab LS
Extended cab models add a second row of seating and usually include rear doors with corresponding rear speakers. The common factory arrangement is 6.5 inches in the front doors and 4x6 inches in the rear doors or rear panels, configured as two-way units in each location.
Below is a quick reference of the extended cab configuration:
- Front door speakers: 6.5 inches (165 mm), typically a two‑way unit.
- Rear door/rear panel speakers: 4x6 inches (approximately 100 x 150 mm), typically a two‑way unit.
Concluding for extended cab LS: most extended-cab S-10 LS trucks use 6.5" front speakers and 4x6" rear speakers, with the exact placement depending on the door design and trim level.
How to verify the exact sizes in your truck
Because factory configurations can vary by radio option, trim package, and production year, it’s best to confirm the exact sizes on your particular vehicle. Here are practical steps to verify:
- Inspect the door panels: remove the grille or paneling around each speaker to read the stamped size (e.g., 6.5", 4x6").
- Check the owner’s manual or original factory documentation for the radio and speaker package specs.
- Measure the existing speaker openings with a ruler or tape measure to verify the diameter and mounting depth.
- If you’re upgrading, bring a tape measure when shopping for replacements and note the mounting depth to ensure a proper fit.
Concluding verification: sizes can differ by cab type and option, so physically inspecting the openings or consulting the factory documentation will give you the precise measurements for your specific 2003 S-10 LS.
Summary
For most 2003 S-10 LS trucks, the front speakers are 6.5 inches. Regular cabs typically have no rear speakers, while extended cabs usually add 4x6 inch rear speakers. Always verify on your exact vehicle, as configurations can vary by cab style and radio package. If you plan an upgrade, the 6.5" front speakers are a common swap target, with 4x6" rears for extended cab models.
