Subaru Speaker Adapter Combo Kit Front + Rear v1


Subaru Speaker Adapter Combo Kit Front + Rear

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). 


  • Front Speaker Adapter Kit PLUS our 5.25" Rear Speaker Adapter Kit. 
  • 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.

Front Doors (6.5" applications)

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

Front Doors (5.25" applications)

  • Cutout Diameter: 0"-4.9"

  • Tip: when shopping for coaxial rear speakers, find one that has a flush mounted tweeter, versus a tweeter that extends past the woofer body. This will make for an easier install.
