[QUOTE="hispls, post: 8820119, member: 614752"] For the most part, shape of the box doesn't matter, what you're aiming for is the springiness you get from that specific volume of air so angles and custom shapes to build around wheel wells or whatever should only matter for whatever volume of air they give or take. Before you get really crazy with this, keep in mind a box that will fit in your trunk may not fit in your trunk if you build it outside of the vehicle and try to shove it in there. Mock something up with cardboard if you can or at least try to dry-fit the sides of the box to confirm you can get it into the trunk before you glue and screw the whole thing. Performing surgery on an assembled box to get it to fit into a trunk is a colossal pain in the arse. Bandpass with the port up into the passenger compartment is a good strategy for sedans, ported box can do OK as well but only testing different configurations will tell you which direction aiming the sub(s)/port will be optimum. IF you really want to go crazy and build the box inside the vehicle you may be pigionholing yourself into only being able to use that particular woofer (or one with similar specs) and you may have a difficult time building it in a way that the sub can be removed/replaced/upgraded if needed down the road. I don't think your choice of wood will make an audible difference and unless you're using steel or granite or something exotic larger panels will probably benefit from bracing with any common 3/4" lumber.
