kamanian is that 6 cubes before or after displacment and must be nice 200lade

that was before, so ~8,5 after.

I could see going smaller though as you are putting alot of power to them.

Could u give me a design to go off of?

 

[s12mm4000 10+ year member]

so if i make my box

35.5'' wide

15'' tall

24'' deep

that would give me 5.97 cubes

how many aero ports and how long should they be?

4"=12.54sq.in

6'=28.26sq.in

you want at least 12 sq.in per cu. ft of box. For Spl, I like to go bigger with the ports, so 18-20/ft

you would beserved wellto contact RAM and pay him a small fee to give you a good design. He is good at what he does
