4 nighshade 18s yukon xl build 155+ 16v minus the ********

cause i had some boxes laying around and wanted some bump in my truck i should have my 2 18 test box in tomorrow and be charging at 18.4 im only doing 2 right now to figure out the proper air space for 4 of them before i build the monster box 2 layers of birch all around and a tripple top flush mount and 4x4 45ed for all corners and 2x4 for bracing

 
well i built my test box today it 8.4 cubes after dis with 2 6 inch aeros tuned to 28.5 and it looks like i need more port area from how its acting im thinking like 3 6 inch aeros what do you guys think i will have pics of the box build up soon

 
i also need to tune higher cause the fs is 41htz on my 18s the fs on the axis is 22htz witch is how i got away with a 9.5 cube box with 57 inches of port tuned to 27

 
after i add the 3rd aero to my test box i will have 10.6875 inches of port per cube instead of 6.7 as it sits witch should help and will be tuned to 35hrz

 
and if i go 16v and i murder the subs then i will get differant speakers or run one amp on all 4 if i find out i need 4 6 inch areos for 2 18s then i know im going to have to do a slot port instead of aeros and i want to find out my tuning

 
i have $60 in the test box my the box im building for the 4 18s will be over $200 so got to make sure it at least close to what the subs want
