[Stang Jr.]

I have a Rockford deck installed in my stang, and whenever I get her up to about 2k rpms, the faceplate starts rattling. I imagine it's because it's detachable and it can't be mounted that securely, but is there anything I can do to stop this rattling?

Those faceplate are spring loaded and don't rattle. Maybe the tension springs are worn out or missing. Try stuffing some realy spongy foam behind it for now.
