What size speakers are in a 98 f150 single cab?
The typical front-door speakers on a 1998 Ford F-150 Regular Cab are 6x8 inches. Regular cabs usually do not include rear speakers, while SuperCab/extended cab models add rear speakers that are also typically 6x8 inches.
This article provides a detailed breakdown of the common sizes you’re likely to encounter on a 1998 F-150 single cab, plus tips for confirming the exact fit for your truck based on trim level and factory options.
Speaker size by location
Front door speakers
Before listing the standard size, note that the front-door location is where most trucks of this era use a common, replaceable harness and mounting hole pattern.
- 6x8 inches (common factory size for front-door speakers on 1997–2003 F-150 regular cabs).
In practice, the front-door opening is sized to accommodate 6x8 speakers, which keeps aftermarket upgrade options straightforward across most trims and radios.
Rear speakers
The regular cab configuration typically does not include rear speakers. If your vehicle is actually a SuperCab/Extended Cab, rear speakers are usually installed behind the rear seats and share the same 6x8 inch sizing.
- Regular Cab: no rear speakers by default.
- SuperCab/Extended Cab: two rear speakers, commonly 6x8 inches.
For a single-cab truck, you can expect no rear speakers, whereas an extended-cab model follows the same 6x8 sizing for the rear deck panels or rear side panels.
How to verify the exact size on your truck
To be certain you order the correct replacements for your specific build, follow these verification steps.
- Inspect the door panels to confirm the mounting hole pattern and measure the opening to verify it matches 6x8 inches.
- Check the original window sticker, trim level (XL, XLT, etc.), or the vehicle’s build sheet for the factory speaker size specification.
- Remove a door panel carefully to physically inspect the speaker size and mounting depth if you have access to the vehicle.
- Measure the depth and clearance behind the mounting surface to ensure you select speakers with compatible mounting depth and grille clearance.
These steps help ensure you select the correct 6x8-inch replacement speakers or appropriate adapters for your exact truck configuration.
Summary
For a 1998 Ford F-150 single cab, the standard front-door speakers are 6x8 inches. Regular cabs typically have no rear speakers, while SuperCab (extended cab) models include rear speakers that are usually 6x8 inches as well. Always verify with your vehicle’s build information or by measuring the mounting openings to confirm fit before purchasing replacements.
