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

i know that im thinkin 15 to 16 cubes common camber after dis probily 15 cubes cause in a common camber you need less port area and i need a kinda small box cause of the 10 to 11 k they will be seeing

 
if i do seperate chambers then test box with 2 subs just need to be doubled after i figure out tuning on it im thinking 7.75 cubes each chamber with about 80 inchs of port tuned to 35 but i need to do testing to be sure

 
ok. so here is my advise.... i originally said the port was too small and you would be wasting your time with the aero ports.

so now i advise you to think. you have 18s, 12s run on 4 cubes. you should be running at least 6 to these. you have the room! and build a giant slot port and you will get what your seeking after.

nightshade 18's like small boxes...4 cubes per 18 is fine
