hey, i'm willing to admit i dont know what i'm doing. and i dont
doubt any of the information anyone has given me on here, i'm just
practicing "learning by asking stupid questions." lol. i just want
to know if i can make anything out of my ingorant assumptions or if
i'm trying to think way beyond my understanding of acoustic physics.
apparently it's the latter case...

We are saying (many of us from first-hand experience)
that just building random boxes for car speakers has a
very low likelyhood of success or satisfaction.

is there any easy way to measure the Theil Small
parameters of my drivers?

I'm certain that there are several good tutorials on the
methodology in that list. Many serious speaker builders
perform DIY T-S measurements. But you will have to
decide whether your particular situation is worth the
hassle.

i've read some information on DIY Theil Small
measurements and it sounds pretty complex...

It is not trivial. That is why most manufacturers of
drivers intended for conventional use will publish
the numbers for your convenience.

But those who make drivers for cars typically don't
bother, because nobody modifies their car to fit the
characteristics of the speakers.
