What size speakers are in a Toyota Highlander?
The short answer is that speaker sizes in a Toyota Highlander vary by model year and trim. In most recent models, front and rear door speakers are 6.5 inches, and higher trims equipped with the JBL premium audio system include an 8-inch subwoofer in the cargo area along with additional speakers. Base models typically use a smaller, standard setup with no dedicated subwoofer.
Across generations, Toyota has offered two main audio configurations: a standard six- or eight-speaker system on base trims and a more expansive JBL system on higher trims. While door speakers generally measure about 6.5 inches, other components such as center-channel speakers and tweeters are smaller (roughly 0.5 to 0.75 inches for tweeters) and can differ slightly by year or trim. For exact measurements, check your vehicle’s documentation or inquire with a Toyota dealer for your specific year and trim.
Two primary audio configurations in recent Highlanders
Below are typical sizes for the two common setups you’ll encounter in modern Highlanders. Remember that exact numbers can vary by year and trim, so use this as a guide and verify for your vehicle.
- Front doors: 6.5-inch speakers
- Rear doors: 6.5-inch speakers
- Tweeters: 0.5–0.75-inch dome tweeters (often in the A-pillars or dash)
Conclusion: In the standard (base) configuration, you generally get six speakers total (four door speakers plus two dash/tweeter units), with no dedicated subwoofer on most trims.
JBL Premium Audio (optional on XLE/Limited/Platinum)
On higher trims with the JBL premium system, the door speakers remain around 6.5 inches, but you gain additional speakers, a center-channel element, and a subwoofer in the cargo area. Here are the typical sizes for this setup.
- Front doors: 6.5-inch midrange speakers
- Rear doors: 6.5-inch midrange speakers
- Center channel / dash speaker: approximately 3.0–3.5 inches
- Tweeters: 0.5–0.75-inch dome tweeters
- Subwoofer: 8-inch (in the cargo area)
Conclusion: The JBL system adds more total speakers and an 8-inch sub, and is commonly marketed as an 11- to 12-speaker setup depending on the year and trim.
How to verify sizes for your specific Highlander
If you want exact measurements for your exact vehicle, use these steps to verify.
- Check the owner’s manual or the audio system specification section for speaker sizes.
- Look up the trim and year in Toyota’s official service or parts catalogs, or ask a dealership parts desk.
- Inspect the door panels: measure the mounting diameter or read any stamped size on the speaker housing.
- Ask a dealer to pull the build sheet or VIN-based specifications, which list the installed audio components.
In short, for precise numbers, rely on your specific Highlander’s documentation or a knowledgeable dealer, as sizes can differ between generations and trims.
Summary
For most modern Toyota Highlanders, 6.5-inch door speakers are standard across trims, with an 8-inch subwoofer included on higher-end JBL configurations. Base models tend to use a simpler six-speaker setup without a dedicated sub, while JBL-equipped trims add more speakers and an 8-inch sub. Exact sizes can vary by year and trim, so always check your vehicle’s manuals or consult a dealer for your specific model.
