Moving right along ....I needed to figure out a way to mount my Polk Audio tweeters before painting the car. I decided long ago that I wanted them up in the corner of the windshield, in the headliner, just outside of the visors. They have a surface mount receptacle they can be mounted into. After contemplating how to mount them, I decided to make a piece of sheetmetal to double up the roof so I had something to attach them to. Here's what I came up with. I will need to weld a nut or tab onto this piece so the height and angle can be adjusted when the headliner is installed.
