I have a 97' Max. Will these dimensions work...11.75"(H)x25.75"(W)x13.75"(D). The reason I'm asking is because I don't have my car right now, and I came across a good price on a box and subs. Otherwise I would have measured myself. Thanks.

 

I have a box sitting behind me that is 8 1/2 high x 20 Deep on the ends 22 in the middle and about 40 or 42 long. All dimensions inches. It can slide in and out of my trunk with ease. But I think you want that box to sit in one place and stay there. I am sure it will fit but it may not fit in the place which sounds best or which is most convenient. I would make a model of the best fitting box out of cardboard and then determine how much air volume you will have inside the same shaped box constructed of 3/4 inch thick minimum MDF with substantial bracing. From that you will have to choose the best woofer for the given maximum volume. You can always make it smaller or add filler material to reduce this volume.
