How do you figure? It takes up the whole back of my Yukon and goes over the seat a bit, it's def 12.5 cubes. Torres Calc states so, so i dont see how it's not 12 cubes? I used like (8) 4x8 sheets to build it. The box is 21.75 x 48 x 32 , put that onto paper you'll see it's 12 cubes.
Not when you change your wood size from .75 to 1.5 like it is. I’ve done multiple 12-14 cube two 18 builds. For it not playing high I couldn’t tell you. I always tuned to 35ish and peaked in the mid 40hz range. I would guess you wouldn’t be playing low enough if your ports were being choked by the hatch. I would double check your LPF on headunit and amp. Then clamp your amp and see what you are getting for rise.
