I I have a new set of 6x9s for the package tray. I bought the tray from cj and i really like it. However there has never been speakers back there. What is the easiest way to drill the holes for the screws. since the back glass is installed i cant really get in there. If i go from undernieth, how do i make sure the holes are lined up?

 

Remove the package tray, otherwise return those speakers unless you can deal with them not being installed exactly right. you can probably get close if you make a template or something
