Yes, and I've never worked with fiberglass before. Another thing, I want a downfiring enclosure, because I'm pretty sure my car is going to get broken into again, and my theory is, if they can't steal it they will trash it. So if it is downfiring they cannot touch the subs, if it is forward firing they can ruin the subs, even if there are grills over them, which there would be, they still could ruin the subs. Down firing is what I decided on, how much space do I need to leave between the sub and the floor? Also what if I just paid you for blueprints of a box that way you wouldn't have to send anything but an email. Haha and I agree, not sure hom much that jack is going to help being that my truck is lifted, might need to invest in an aftermarket jack. But I don't think I'm going to be doing any glass work to get up in that area. So far what I have, It maximizes the space under the seat, but its just a rough design out of cardboard. A little scared to start with the wood, need to do some more research first. And with the 2" seat lift you didn't have to extend the locking tabs on the back of the seat?
