Cabin volume vs box volume. when building a wall do think the box should have more volume than the cabin? Spl should be louder in the smaller of the 2 right.

When the box volume is larger than the cabin funky things can happen. With my car we have loading issues usually drivers side door has to be open (where prot is located) in some cars it'll be much louder sealed up rather than all open. Personally I would try to keep the cabin larger than the enclosure, but that's just me.
