Subaru Speaker Adapter Kit for 6.5"

Subaru Speaker Adapter Kit for 6.5"


Subaru Speaker Adapter Kit for 6.5"

Made in the USA and reviewed across several publications, Subiesport, IWSTi, and NASIOC, the ia-Performance stereo speaker install kits is one of the most innovative kits on the market. These are constructed of Polycarbonate, which is 2x stronger than ABS, commonly found in other brands. Their universal design allows the adapters to be stacked, or even flipped, to meet the mounting depth and cutout diameter needs of each speaker.

As an added bonus, the adapters are manufactured right here in Colorado, USA.

FACT: The factory Subaru door design significantly limits the speaker options to the point of having next to no aftermarket choices.

Through the implementation of our injected molded adapters, you now have the option of running virtually any aftermarket speaker while maintaining the factory door covers*. Plus, the ease of which our kit installs will make anyone feel like a pro (no cutting nor drilling required). 


  • 4 Front Rings, enough to fit 1 pair of speakers. If a 4 door (2 pair) install is desired, then purchase one of our 'Combo' kits
  • Comprehensive installation kit  

Our adapter kits are designed to work with speakers within the following size dimensions. Please refer to the manufacturer's website for your model's dimensions. 

See the above APPLICATIONS and FAQ tabs for additional info.

  • Cutout Diameter: 5.0"- 5.9"
  • Mounting Depth: 0" - 2.92" **

*Note: our adapters fit speakers meeting the size requirement chart above. These sizes fit 99% of all speakers in the mainstream market. Please consult with your speakers' manufacturer for fitment dimensions.

    Awesome all around

    Great product, unreal fast shipping. Thank you, A+

    Fits perfectly

    After attempting to replace the speakers in my 1999 forester and contemplating drilling new holes in the door, I purchased these. They arrived quickly and were simple for even my 15 year old to install. Excellent product!

    Fast, easy, do it

    This kit was perfect for installing new speakers into my 2001 subaru forester, didn't even need to remove door panels. Never installed speakers before and did front and back in under an hour.

    20 minute install

    This product did exactly what it said it would, I installed my 6.5" speakers in about 20 minutes. These are a MUCH better option then the "fits with modification" adapters I had been told were my only option. Couldn't be happier that I found iaperformance, and I would recommend these to anyone looking to put speakers in their Subaru.

    Adapters Worked Great

    Adapters worked great with MTX TN653 6.5" coaxial speakers in my 2002 WRX. Thank you!
