So I want to install a voltage gauge in my car, but dont want it to be seen. Since I already have my satellite radio installed in my ash tray, I cannot put the gauge there. So I thought of this. I want to semi-flush mount it into my fuse box cover. I started to trim an extra cover, and this is what i have for now. Next I will fiberglass the gauge bottom so i can paint it and make it all smooth and matching in color. Any opinions?
