Subaru Speaker Adapter Combo Kit Front + Rear v2

Subaru Speaker Adapter Combo Kit Front + Rear v2


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.

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).

    Works as advertised.

    These brackets worked great when installing aftermarket speakers in the front of my 2010 Subarus forester. I had a lot of trouble finding brackets for my car online so glad I stumbled upon iatuning.

    Intuitive and Well Made

    In this day and age when people are quick to complain about things... It is a pleasure to write a 5-star review for this product. I have a 2008 Subaru Outback with 60k miles that looks like it was just driven off the showroom floor. I wanted to add a custom head unit so I bought an AtotoS8 Ultra. The sound was okay but I wanted to add some Infinity speakers also. When I started reading about some people's experience in swapping out speakers I heard several who would butcher the stock speakers in order to make the new speakers fit. I didn't want to do a half a** job. I want it right! The speaker mounts that Infinity provided were nowhere close to what I needed. I already knew this. I took a chance and ordered these speaker adapters based upon the reviews. I am SO glad I did. No instructions are needed really and they give you enough screws and hardware to build a second car! They cover any eventuality you may run into including new door card plugs just in case you break some pulling off your door card! Who does that? THESE GUYS DO!

    Do yourself a favor and make life easy on yourself and you will be swapping stuff out in no time!

    Thank you iaTuning!!!

    Unbelievably Easy to Install

    If you are contemplating getting these get them. My front windows finally roll all the way down without hitting my Rockford T2 components. I noticed the sound quality increase significantly after installing these as they brought the woofer closer to the speaker hole opening in the door panel. Even if your speakers fit without these, installing these will provide much better clarity in the midrange. Pay the little extra and get the front and rear kit. You will be glad you did.


    These fit perfectly and allowed me to install my aftermarket speakers. Easy install with no drilling required. The kit even came with the hardware to mount the speakers and the holes already predrilled!


    There are not a lot of options when it comes to Subaru aftermarket parts. These are the real deal. Fit perfectly for my Rockford Fosgate 6.5s in my 2011 Forrester. Highly recommend!
