I am new here so hello to all.  My question has probably been asked a thousand times across the internet.
Can anyone answer, Steve perhaps, I see the build plans are all for 10" and larger subs. Can boxes like the Death Box, Death Box II or Inverted Wedge be scaled DOWN to fit a 8" or 6" inch sub.  
I drive 2014 Chevy Spark and the package tray has about 4 cuft total.  I am looking for SQ over SPL but want some bump in the trunk.  I would gladly buy the plans for one of the boxes mentioned if they were scaled down.
Thx,
Patrick

In a hatchback car that small, I'd put a decent 8" or 10" driver in a sealed box and be done.
No need for complicated.

Thank You to all for the quick response and advice.
Steve I simply state that I need the plans scaled down for a x" sub when ordering them?
