I would like to put my infinity 10.1 on the door panel high up and in front of the vent where I have a flat surface to mount BUT I would like to know what's behind that location without removing the door panel first. Will I hit a support for the door back there? I have considered using a double sided carpet tape so as not to drill holes in the panel. I think the tape would work but I don/t know how easy it is to remove later as this car will be sold someday. thanks Oh and by the way I'm not trading my silver bullet sub as I have "bad nephew" looking for the 400bdg in his junk pile so I can bridge the 280gx. by by
