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.
