Custom Tweeter Install
I'm installing an entirely new audio system in my Acura TL and will be mounting tweeters in the A pillars where the stock tweeters once were. I cut out the factory mounting baskets with a dremel and need to attach a couple aluminum posts to the inside surface of the grill in order to secure the new tweeters. I tried using JB Weld, but it didn't hold (should've known better). What adhesive do you guys recommend I use to secure the metal posts to the smooth plastic grill? FYI, the picture shows nylon spacers over the studs which provide a flat surface for the mounting clips (not shown) to rest on. I'm open for suggestions on alternative fastening methods as well. Also, what type of plastic is this? I'm looking at two part epoxies by 3M and they have three different epoxies for different plastics. My best guess is polyethylene or polypropylene. One example is 3M Scotch-Weld DP100 two part epoxy, which is good for ABS, PVC, polyolefins, and metal. I could also go with a nylon binding post if a plastic to plastic bond would be more secure, not that it needs to withstand any significant load.

With little tweeters I don't use their mounting hardware or studs. I glue the speakers directly to the plastic, not the grill. I've used 5 minute epoxy and hot melt glue and both have worked well.

Thanks fellas. I thought of gluing the tweeters themselves, but didn't want to do anything permanent in case one of them blows and needs replacing. I suppose hot glue would peel off pretty easily if I needed to replace the tweeter. However, I bought the posts and other hardware yesterday from the hardware store so I'd like to use them if possible. I think I'll try using hot glue to secure the posts.
