I am in the process of getting ready to take out my 3rd row in my durango and put in an SE15 or an SE12 or two sealed and making it look like I have no system. Has anybody done this or anything like this on the forums (excluding false floors in the trunks of cars). More specifically replacing the 3rd row with their system in any SUV. I wanted to see if anybody has any tips or any experience doing this before I decide that its a bad idea and change my mind. I know that fiberglassing would probably be my best bet, but I have no clue on how to fiberglass and have only seen step by step fiberglassing photos online. It looks easy, but has anybody done this with mdf? Or at all? This is currently the only pic that I have of the back, also I am trying to get rid of these 8's and the box all together if possible.
