I own a 2006 Toyota Matrix XR with a 1ZZ motor. These fit perfectly in the front doors, I would suggest getting your own bolts and nuts. The nuts they give you are garbage. In my car this adds about .5 inches so you get a full 2 inches of mounting depth with the window rolled all the way down. They didn't however work on the back doors, but those doors really didn't require anything special anyway.

Got this for my 2006 Toyota Corolla and it fit the front doors perfectly.No modifications needed what so ever.I installed 6.3/4" Kicker KS and they fit perfectly aswell.Overall great buy!!

Hell yeah this product works. You should buy it. Like right now.

Perfect fit in the front door in my 2015 Toyota Corolla, thank you.

I used these on an '05 Subaru Legacy. The screw holes didn't match up but that was expected since this is actually for a Toyota. I used self tapping screws and made my own holes. It gave me enough space behind the speaker to fit my NVX VSP65's.

These were a nice fit for our 2010 Corolla. Made the install easier and go faster.

Fit really well. the hardware they give you isn't great and if I had looked before I was installing them I would have bought different nuts and shorter screws.

mounted some Infinity primus to these. Great build and simple installation.

They fit perfectly In my 2016 RAV4 and we’re easy to install. They lined up perfectly with the factory rivet holes and then just bolted in like a breeze.

These adapters worked very well for installing new speakers in my car. Stock speakers came with speakers being held in place with an adapter being integral. This kit let me install the new speakers without modifications.

Perfect fit for the Scion xB, made for an easy install of aftermarket speakers.
