Fox box acoustics single 10" box
#64
im also tryint a sealed foxbox for a single 10 for 2012 screw. width of your box is negligible, as the floor back there goes from door to door uninterrupted. these are the dimensions under the seat from the side, if your box fits within these dimensions then i see no reason why it wouldnt work for the late model screws. (the 6 and 12.5 distances could come out a bit more if necessary, these make it a little shy to near flush with edge of the seat). im thinking if anything will be an issue it will be the depth, sounds like you have a lip back there against the wall that it rests on that we dont have in our trucks =(
