Long story short, I have a speaker with 4 mounting holes and a 2mm think piece of fiberglass which has a hole the correct size of the speaker. I have no way to access the back of the fiberglass to hold a nut.
How would you mount these speakers to the fiberglass when you cant get around to the other side? I would prefer not using just screws as over time they have failed in the same situation.
Thanks!
