What size are RSX speakers?
In most Acura RSX models, front-door speakers are 6.5 inches in diameter, while the rear deck typically uses 6x9-inch speakers. Exact sizes can vary by year and market, so it’s wise to verify before upgrading.
The RSX was produced by Acura from 2002 to 2006 and shares its layout with several Honda platforms of the era. For most trims, the factory setup centers on a 6.5-inch woofer in the front doors and a larger rear-shelf speaker arrangement. This article lays out the common sizes and how to confirm the fit for your specific vehicle.
Typical RSX speaker sizes by location
Use these general guidelines when shopping for aftermarket replacements, but remember to double-check against your exact vehicle since there were regional and trim variations.
- Front doors: 6.5 inches (165 mm) in diameter. This is the standard size for the main woofer in the RSX’s front doors.
- Rear deck/shelf: 6x9 inches (approximately 152 mm x 229 mm). This larger size is common for the rear speakers in RSX configurations.
These sizes cover the majority of Acura RSX cars from 2002–2006. If you’re unsure, measure the mounting diameter or consult the factory documentation for your exact year and trim.
How to confirm the sizes on your RSX
To ensure your upgrade fits correctly, verify the exact specifications for your vehicle. The steps below help you confirm accurately if you don’t rely on generic year-to-model guidance.
- Remove the speaker grilles or door panels to access the speakers and measure the mounting diameter.
- Check the stock speaker labels or part numbers; cross-reference with Acura/aftermarket catalogs for the exact size and impedance.
- Consult the owner's manual or a service manual for the RSX model year to confirm the recommended speaker size.
Knowing the exact sizes helps you select compatible aftermarket replacements and avoid fitment issues related to depth, mounting brackets, or impedance.
Notes for readers upgrading RSX audio
Beyond diameter, consider mounting depth, voice coil diameter, impedance (ohms), and power handling. The RSX’s factory head unit and any installed amplifiers can influence how your upgraded speakers perform, so plan a setup that maintains sound quality while staying within electrical limits.
Summary
The RSX commonly uses 6.5-inch front-door speakers and 6x9-inch rear deck speakers. Exact configurations can vary by model year and regional market. Always verify by measuring or consulting the service manual if you’re planning an upgrade.
