What size are the rear speakers in the Tacoma access cab?
The rear speakers in the Toyota Tacoma Access Cab are typically 6.5 inches in diameter (about 165 mm).
This article explains the standard size, possible year/trim variations, and how to verify the exact fit for your vehicle when planning a replacement or upgrade.
Typical rear speaker size in the Tacoma Access Cab
In most Access Cab configurations, the rear doors accommodate 6.5-inch speakers. These are usually two‑way coaxial units and are compatible with a wide range of aftermarket 6.5-inch replacements. If you are upgrading, be mindful of mounting depth and the potential need for adapters if your head unit or amp setup has unusual spacing.
Variations by year or trim
While 6.5 inches is the standard, rare trims or changes in generation updates can affect the exact mounting depth or screw pattern. To be certain, check the OEM parts diagram for your specific year and trim, or physically measure the installed speaker diameter through the rear door panel after removing the grille.
How to confirm the exact size for your Tacoma
For precision, consult Toyota’s official service catalogs or your vehicle’s VIN-specific parts diagram. If you’re replacing, confirm the impedance and mounting depth of your chosen speaker—most common aftermarket 6.5-inch models are 4 ohms, but impedance can vary. When in doubt, bring the existing speaker or a caliper to the parts counter to verify fit.
Notes for aftermarket purchases
Most 6.5-inch aftermarket speakers will fit in the Tacoma Access Cab rear doors, but some depth constraints or bracket differences may require a shallow-mount design or minor trim work. If your vehicle has premium audio with factory subwoofers or a bass management system, verify that the rear speakers are not part of a larger enclosure before replacing.
Summary
In short, expect 6.5-inch rear speakers in the Tacoma Access Cab, with rare exceptions depending on year or trim. Always verify by checking OEM diagrams or measuring the installed unit before purchasing replacements to ensure a clean fit and proper impedance alignment.
