Sub in trunk + wood + air setup... How would I approach this?

[TheWolfe]

As the title states, I've been thinking about upgrading my audio all around (non-bose base model Z) and putting a 10" or 12" sub in the trunk facing upwards where the spare would normally go. I love nice trunk setups, and I don't want this Z to be much different from the nicer trunk setups I see at car shows--especially considering the "trunk" is in the same cabin as the driver and passenger and is seen very easily.

Anyways, the gist of this is I want a 10"/12" sub (can't decide) in the middle facing upwards, a wood laminate or something instead of the carpeted mat, and a nice looking air compressor and all of that on this theoretical build. My question is like... what order do I do all of that stuff in? Do you I put the wood in, then get the sub, THEN the compressor? I feel like once the sub/compressor is in, I won't really be able to add that hardwood/laminate floor in there. I have no idea how that kind of stuff goes, and there's a strong possibility this won't ever happen, but I'm just kind of entertaining the idea a little bit for now.

If you have any other suggestions, feel free to let me know!! I felt that with the sub where the spare goes, I could bend little 1/4" aluminum bars or something and make a rail that goes over the sub so I can still use at least 75% of my trunk if I have to. Seriously though, if you have any better ideas, I'd love to hear them!
