I took the stock grills out of the car, of course, drilled pilot holes in each of the surrounding brackets. I used rockford fosgate P1P tweeters, which have a flange on the outside of them, so I dremeled that off to fit snugly inside those brackets. Then I took epoxy and stuffed it in the spaces between the brackets and the tweeter, making sure that the epoxy was stuffed into those holes as well. That will secure that if the epoxy doesn't stick to either the bracket or the tweeter, that it will stay in place by the holes. That's just what I did. I don't have them hooked up at the moment, because after i got them in and got my amp hooked up I had an issue with a channel and I had to send the amp in for repairs. But off of the radio it sounds pretty good. However, I do like the idea of changing them and where they are. Maybe fiberglass some pods to face forward that are connected to the factory grills somehow for removal purposes. That was a good idea, bsbabcock.
