i've seen it time and time again. the false side walls in the trunk. anyone have any tips/tutorial info on how to get these properly built and to stay in place. looking to make out of wood and cover with carpet or vinyl. Fiberglass is something that is way down the road. basically when i was adding the sound deadening to the trunk, the old carpet for my trunk got completely demolished in the garage, so now its time to finally get the trunk taken care of. pretty much have the false floor and the sub box taken care of, but just wondering what you guys have done in the past as to what works best. If it helps at all, the car is a 2002 Mitsubishi Galant. Box is a 3.25cu.ft box that gives me about 5-10 inches of play between the wheel wells. Amps will be mounted to the back of the box, so basically the side walls are just there for form, fit, and finish. I'm basically sick of looking at a crappy "naked" trunk and want to be able to use my trunk again.

Well you more or less pick the spot you want the vertical wall to be located and then start out with a square piece of cardboard or the like. You then want to trim it to shape to fit wherever you want that vertical wall to sit. Presumably the bottom will be flat as the floor is probably flat. The rear edge will follow the contour of the back of the car as it curves down, the top might be flat or curved slightly to follow the top of the trunk and then the front will either meet up with another trim panel that spans across the width of the trunk, or is shaped to follow the shock towers or whatever is there. You can start out by eyeballing and then keep trimming to hone your shape. You would want your wall probably located past the trunk opening though unless you want to make a top for it. 1/4" or 1/2" MDF as the final product works great for flat surfaces.

Since the trunk floor is flat and the top might be as well, an L-shape from 2 strips of MDF can be used so you can secure one side of the L to the floor and one side for the false wall piece. You can make this long enough to get as much contact with the floor and wall piece as possible. You can make small L pieces too for other areas and adhere those either by screws or adhesive to the trunk metal. The false wall can attach either by push-pins ('christmas trees') or even a friction fit if you get it to fit tight enough.
