Speaker sizes by configuration
In the 2004 F-150 lineup, speaker sizes are tied to the cab style (Regular Cab, SuperCab, SuperCrew) and the factory audio package. The sizes below reflect the most common factory configurations and reliable aftermarket replacements; exact sizes can vary by trim and radio option, so verify for your specific truck.
- Front doors: 6.5 inches (165 mm) in diameter, typically a two-way coaxial or component setup.
- Front dash: commonly 4x6 inches (101x152 mm); some trims used a 5x7 inch dash speaker.
- Rear doors (SuperCab or extended cab): commonly 4x6 inches (101x152 mm).
- Rear doors (SuperCrew or crew cab): commonly 6x8 inches (152x203 mm).
Bottom line: Regular Cab models generally have 6.5" front-door speakers with no rear speakers; SuperCab models typically add 4x6" rear speakers; SuperCrew models commonly use 6x8" rear speakers. Use this as a baseline when shopping for replacements, but confirm with your exact build.
How to confirm the exact sizes on your truck
Because Ford offered multiple audio options in 2004, the only reliable way to know your exact sizes is to check your vehicle's build details and inspect the speakers. Start with the VIN, window sticker, or the factory service manual to identify the original speaker sizes. If those aren’t available, you can remove a door panel to read the speaker label or measure the mounting hole diameter and mounting depth to determine the correct replacements.
Summary
For the 2004 Ford F-150, front-door speakers are typically 6.5 inches, while dash and rear-door sizes depend on cab type: Regular Cab usually lacks rear speakers, SuperCab uses 4x6-inch rear speakers, and SuperCrew commonly uses 6x8-inch rear speakers. Always verify your specific configuration before buying replacements, and consider compatibility with your head unit and impedance when upgrading.
