What size speakers are in a 2015 Ford Focus?

In most 2015 Focus models, the front-door speakers are 6.5 inches in diameter and the rear-door speakers are 5.25 inches. The optional premium Sony audio system generally uses the same door-speaker sizes but adds additional tweeters and a subwoofer component, depending on market and trim. Always verify with your vehicle’s documentation or VIN if you need exact figures for your specific car.


Standard door-speaker sizes


Below are the typical sizes you’ll find in the standard audio setup on most 2015 Focus models.



  • Front door speakers: 6.5 inches (about 165 mm) in diameter

  • Rear door speakers: 5.25 inches (about 133 mm) in diameter


These dimensions cover the common base and mid-range trims. If your Focus has a different regional spec or an unusual factory option, the sizes could vary.


Premium audio option and trim variations


The optional premium audio configuration (often labeled as a Sony 9-speatter system) maintains the same door-speaker sizes but enhances overall sound through additional speakers and tweeters. The exact arrangement can vary by market and model year, with extra components like tweeters in the A-pillars and a subwoofer pathway in the trunk in some configurations.



  • Door speaker sizes remain: 6.5 inches in the front and 5.25 inches in the rear

  • Additional speakers and tweeters are added for richer high frequencies, with a subwoofer present in some markets


Note: Size consistency is common, but regional differences and option packages can affect the precise speaker layout. Consult your vehicle’s spec sheet or dealer for exact details.


How to verify in your vehicle


To confirm the exact speaker sizes for your car, use these methods.



  • Check the owner's manual or the original equipment specification (OES) sheet for your VIN

  • Physically inspect the door panels and measure the speaker diameter or look for a sticker on the speaker itself

  • Contact a Ford dealer or use Ford’s online parts catalog with your VIN for precise measurements


Verifying the exact sizes is especially important if you’re upgrading or replacing speakers.


Aftermarket considerations


When ordering aftermarket replacements for a 2015 Focus, plan for 6.5" front-door and 5.25" rear-door speakers as the standard sizes. Depth and mounting depth vary by model and trim, so check compatibility before purchasing adapters or shallow-mount options.


Summary


The 2015 Ford Focus typically uses 6.5-inch front-door speakers and 5.25-inch rear-door speakers. The optional premium Sony audio system keeps these sizes but adds more speakers and tweeters for higher fidelity. Always confirm exact specifications for your vehicle using the VIN, owner’s manual, or a dealer to account for regional differences or optional equipment.

How do I know my car speaker size?


You can find your car's speaker size by checking the owner's manual, using an online vehicle lookup tool from a car audio retailer like Crutchfield, or by physically measuring the speakers after removing the grilles. The simplest way is often the owner's manual or an online lookup tool. Common sizes include 5.25 inches, 6.5 inches, and 6x9 inches, but your car may have other sizes or a combination of different speakers.
 
How to find your car's speaker size

  • Check the owner's manual: Your manual is the fastest way to find the exact speaker sizes for your vehicle. You can often find a digital copy online by searching for your car's year, make, and model plus "owner's manual". 
  • Use an online database: Websites like Crutchfield have tools where you can input your car's year, make, and model to see which speakers are compatible and their sizes. 
  • Measure the speakers directly:
    • Remove the speaker grille: to access the speaker. 
    • Measure the diameter: of the speaker across its widest point. 
    • Measure other dimensions: like mounting depth and height, as these are also crucial for choosing a replacement. 
  • Visit a professional: A car audio specialist can quickly identify the speaker sizes in your car. 

What if the speaker size isn't standard?
  • Measure the opening: Some manufacturers use non-standard sizes like 6x8 inches, especially for Ford vehicles. Measure the opening to find out what fits. 
  • Check for markings: Sometimes the factory speaker itself will have its recommended size marked on it.
