Hey guys I have a 212 Acura TL Elite SH-AWD and currently have 2 10" JL Audio W6v3 in there. I have the box built on the step but it is taking too much space and was thinking of some ideas. Im thinking of building my enclosure in the spare tire and taking the tools and tire out. Im thinking of doing 2 10", 3 10", or 2 12". Does anyone know how much cubic feet volume is in there? That way I can determine which subs and how many I can run.
