No shit Sherlock. What I need to know is about how many cubic feet can be had from the 32 width 32 depth 18 tall. It doesn't have to be exact just a general approximation so I know which btl to order 15" or 18". If I multiply the measurements I come up with almost 10 cubic foot but that's before bracing and port so I'm pretty sure a 10 cubic foot box want fit in a chevy cruze trunk. I normally already have the subs and take them to my box builder to build my box but this time I need to know how big I can go so I can order the sub first. And those measurement's are max what will fit. I measured my trunk opening for the width and height so I know for a fact anything in those numbers will fit. I also checked my 18 tall Clearance for the length of the depth and it's good. And on a side note, I had thought about ordering everything else, except the sub from SSA, but if it's this hard to get a simple tech question answered from the SSA tech team I think I best take this $2k some where else. I'm thinking sonic electronics want have a problem helping me.
