Review on Toyota Rear Speaker Adapter: Custom Install Parts for 6x9 Inch Aftermarket Speakers - Compatible with Camry, Corolla, Solara, Yaris by Derrek Fields

I bought these for my 2009 Yaris sedan to replace their ridiculously low quality factory 6x9. I've installed a few mid-range Pioneers and all my life I couldn't figure out why the adapter holes didn't match the factory holes in case the mounting screws go through. Until I turned her upside down. .The way these adapters are shown here is not really ok. Turn them over and you can see what the underside looks like. nope That should actually be great. However, it doesn't matter as no one will see these adapters after everything is installed. They did what I needed for less than $15. Good.
