Custom Box

Sorry but I’m kinda newer to the Car Audio game so I’m a little behind but is it even possible to build a 10 inch ported sub box that’ll fit under a truck seat? I know you’ve gotta have enough room for a ported box but I don’t really know much about building a box in general so any info about building boxes sealed or ported would be really really appreciated because I’m kinda lost on my build, thanks!
