boxes in the trunk

[couchlockd]

so ihave been reading alot of sealing up the trunk for cab fired subs in sealed boxes and the like.

thrugh my research i kinda came to the conlusion that a sealed enclosure (acoustic suspension) in the trunk facing the rear, is in the grand scheme of things is takng the sealed aspect of the box and the trunk and the firewall opening from the trunk to the cab as 2-4th orders on a bandpass enclosure?

does this seem to make sense, like sealed boxes in the trunk are only half of what is really going on in there, as the rest of the sound is determined by the trunk and firewall opening dimensions??

just wanted to discuss this a little bit.
