Subaru Speaker Adapter Kit 5.25" - Rear Pre 2008

Subaru Speaker Adapter Kit 5.25" - Rear Pre 2008


Subaru Speaker Adapter Kit 5.25" - Rear Pre 2008

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). 


  • 2 Rear Adapter Rings, enough for 2 doors
  • 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: 4.4"- 4.61"
  • Mounting Depth: 0" - 2.92" **
  • 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. 

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

    • Subaru Impreza 2002-2007 Rear doors, only fits the rear
    • Forester 1999-2006 models that arrived with a factory 4" rear speaker
    • Forester 2007-2008, will fit but requires inserting the adapter plate's two lower screws at an angle loosely, then tighten down. Alternatively,  the 2 lower mounting holes can be moved slightly which requires a drill and 3/16" drill bit.
    • Saab 92-x, rear door 2005-2006

    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.

    A: The rings are injected molded ABS and or reinforced fiber resin. 

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