Im assuming its just like the Mach 460 tweeter pod? You remove your inner plastic corners where your mirror are. My Pods had one hole in the back for a screw then I retrofitted someafter market tweeters in place, I thought the tweeters just slid tight in the pods, if not there is obviously some sort of bracket needed. What I did to get mine to fit tight was wrap a layer of Foam tape around the tweeter, then it fit nice and tight in the tweeter pod hole, put the cover on and no one would know, worked great.
