Change the speaker ?

Hi !

I would to know if someone here has change the speaker of the Wind ?

Because i tried to do it, but it need braces (sorry it's a google translation of the word "entretoise" in french) which are riveted on the doors.

There is this system on others Renault (Megane 2-3, Scenic 3 ...) but for Renault Wind, it's impossible to found the suitable "braces"

If someone has a solution ..

I think Moving Shadow changed his. Send him a private message to ask, and he may put some pictures up.
