I used them to install the Sundown SA65CS V3 kit. They worked great, were beautiful and durable. The speaker mounting points allowed me to use 8 screws and with the help of some Stinger quick release rings the speaker lined up perfectly with the bracket and had a solid disconnected connection. Be sure to break off the tabs on the inside before inserting the speaker if it is a larger 6.5-6.75 inch speaker as they will likely get in the way and cause the adapter to move distorted with larger speakers. Would give 5 stars if they were a little thicker and had a little more depth.
