Thanks for the reply! Yes, that's what I'm worried about too. Go mess it up after just getting this truck.... lol But want to even out the sound of the new 3.5's going into the front.I haven't done it yet but I have read many posts on this forum where people have (I have replaced the front dash speakers). You do not have to remove the overhead liner but the grill on the speakers is supposedly very tough to remove. There are tabs in each corner and from what I've read you will think you are about to break the grill but it will eventually come off. That's what has kept me away from it at least for now. With my luck I would break them.
