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

screw holes crack and slip very easily, try to get it right the first time. The supplied screws have a rather small head, so the use of washers is recommended. The screws are also too long so if you need them flush with the back you have to grind them down which then melts the plastic threads at the end of the screw from the heat. Finally, this isn't really a direct downside of their product, but your speakers may require you to cut out a corner of the metal frame to allow a standard screw to fit the short corner. To be honest I regret ever wasting time on this, I would just look for speakers sold as "OEM replacements" as some of them come with metal frames which are too big and the Eliminating the need for that crappy mount. Either make your own out of wood or just drill new holes for yourself, use this as a last resort.
