Hello, my colleague has now shot me two beautiful aluminum shots for my Helix S801 comp. tweeter. I wanted to put these nice discreetly in scene on the dashboard of my Volvo V40. Now only the problem remains open, how do I fix the whole thing so that you can see nothing (screws etc.). Would like to remove the original cover grid and then make one out of GFK, which carries the shots. Only how do I then “invisible” them, so that I later the whole Sac he can take off again ? Is there so clips or similar ? Best regards Thomas
