The days I wanted to finally put my tweeters in Holubal and align them decently, as they are currently lying loosely on the dashboard. Now, of course, the question arises; how do I fix them so that they can hold them, but if necessary they can be removed without residue? The surface in my A3 8L is also relatively rough, with “rills”. Can take a photo tomorrow. That is a liquid glue would put itself in the cracks. I think of something like Powe rstrips or real silicone. Secondly, you should be able to remove eig. on one piece. Do you have better ideas?
