What size speakers are in a 4RUNNER?
The front-door and rear-door speakers in most 4Runner models are 6.5 inches in diameter, with some trims using 6.75-inch units. Exact sizes depend on the model year, trim level, and audio package, so check your specific vehicle to confirm.
To understand why the answer isn’t a single universal figure, it helps to know that the 4Runner has spanned several generations with different audio configurations—from base systems to premium setups. This article outlines typical sizes and how to verify the exact fit for your vehicle.
Current-generation realities
In the widely sold fifth-generation 4Runner (2010 onward), the standard speaker sizes you’ll encounter are generally within a common range, but there are exceptions based on trim and regional markets. The guide below covers the most frequent configurations you’ll see on the road today.
Front door speakers
Most front-door woofers are 6.5 inches (165 mm) in diameter. Some trims or regions offer slightly larger 6.75-inch (172 mm) units to accommodate bigger woofs in the same mounting footprint.
- Size typically: 6.5" (165 mm) in most trims.
- Possible alternate: 6.75" (172 mm) in select trims or markets.
In practice, you’ll want to confirm the exact size for your vehicle before purchasing replacements, as the difference can affect fitment and sound characteristics.
Rear door speakers
Rear-door speakers generally mirror the front, with most trims using 6.5-inch units. Some configurations can use 6.75-inch speakers, particularly in higher-end audio packages or regional variants.
- Size typically: 6.5" (165 mm) in most trims.
- Possible alternate: 6.75" (172 mm) in some trims or markets.
As with the front doors, it’s important to verify the exact size for your specific 4Runner to ensure compatibility with aftermarket replacements or upgrades.
How to verify your exact speaker size
Because sizes vary by year, trim, and optional audio package, use precise checks to confirm what your vehicle uses.
- Consult your owner’s manual or the Toyota service specifications for your exact model year and trim.
- Remove the speaker grille gently and measure the diameter of the speaker from edge to edge, excluding mounting hardware, to confirm the size.
- Look for markings on the original speaker or its basket that indicate size (for example, “6.5” or “6.75”).
- If in doubt, contact a Toyota dealer or a reputable car audio shop with your VIN to verify the exact specification.
Knowing the precise size helps prevent purchasing incompatible replacements and ensures proper fitment and audio performance.
Summary
Most Toyota 4Runners use 6.5-inch speakers in both the front and rear doors, with occasional trims offering 6.75-inch units. Exact sizes depend on the model year, trim level, and audio package, so verifying your vehicle’s specifications or measuring the actual speakers is the best approach before upgrading or replacing components.
