ok guys i just got a fi btl 18 that im going to attemp to put in the trunk of my 2000 monte carlo off a rf t30001bd. the box will be around 36x15x21,i was wondering if i should do aero ports so i dont lose any box space or a slot port?

5.25ft^3 before any displacement...you don't have enough room.

Actually... Fi says 5-10 ft^3 ported for the BTL 18"


Mine will probably end up right around 7ft^3 after displacements as I am going external port through the rear deck.

yeah but like Ryan said 5.25 before displacement not after. You could run it in that but you'd have to do ports external.

I took this to mean external aeros... that would be right at 5ft^3 after sub displacement and without bracing... I am sure he could add an inch or two somewhere though...
