What size speakers are in the 2004 Chevy Colorado?
Typically, the 2004 Chevy Colorado uses 6.5-inch speakers in the front doors and 4x6-inch speakers in the rear doors. Regular cabs may not have rear speakers, while extended and crew cabs do. Variations can occur based on trim and factory options, so checking your specific vehicle is recommended.
Speaker sizes by cab configuration
The Colorado lineup in 2004 offered multiple cab configurations. The front-door woofers in most trims are 6.5 inches, and rear-door speakers, when present, are commonly 4x6 inches. Here is a quick breakdown for common setups:
- Front doors: 6.5-inch (165 mm) speakers, typically two-way coaxial units.
- Rear doors (Extended/Crew Cab): 4x6-inch (102x152 mm) speakers, commonly two-way designs.
Note: If you own a Regular Cab, you may have only front-door speakers installed. If you have an Extended or Crew Cab, you are more likely to have both front and rear speakers in the standard configuration.
Notes for upgrade and verification
When upgrading, sizes are the primary factor, but depth and mounting brackets also matter. The steps below help confirm exact sizes for your exact vehicle:
- Check your VIN-specific service or parts catalog to confirm the exact speaker sizes for your trim.
- Carefully remove a grille or door panel to measure the speaker diameter and mounting depth.
- Consult aftermarket replacement guides (for example, 6.5-inch front and 4x6-inch rear) to ensure compatibility with mounting adapters if needed.
- Verify wiring harness compatibility and identify any required adapters or harness extensions before purchasing replacements.
In practice, most 2004 Colorado models follow the 6.5-inch front and 4x6-inch rear pattern, but verifying your specific build prevents fitment issues during an upgrade.
Summary
The 2004 Chevy Colorado commonly uses 6.5-inch front door speakers and 4x6-inch rear door speakers. Regular Cab models may omit rear speakers, while Extended and Crew Cab configurations typically include them. Always verify your exact cab and trim to ensure correct sizes and mounting compatibility when planning speaker upgrades.
