Subaru Speaker Adapter Kit 5.25"

Subaru Speaker Adapter Kit 5.25"


Subaru Speaker Adapter Kit 5.25"

As seen in Subiesport, IWSTi, and NASIOC, we've delivered the most state-of-the-art Subaru speaker install kit on the market, and it's even made in the 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 area enough for 2 doors in total. If a 4 door 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. 

  • Cutout Diameter: 4.4"- 4.9"
  • Mounting Depth: 0" - 2.92" **

See the above FAQ tab for additional info.

    Q: Why do some kits come with 4 rings for just 2 doors?
    A: The adapter plates have a beveled interior circle, which allows for various stacking configurations to accommodate a vast array of speaker cutout diameters.    


    Q: What are the adapter plates made out of?
    A: The rings are injected molded fiber resin. This material is significantly stronger and more dense than ABS. 

    Q: Where are the kits made?
    A: The adapter rings are produced in Arizona with our proprietary mold and the final packaging occurs at our Colorado office.
