Hello everybody, im running 2 lvl 5 12s on a 10k and really want to get a new box that will let them shine to their full potential. I love the LOWS and want to keep the LOWS. I listen to rap, r&b, jazz, and pop. The current box is tuned to 28hz but its just a regular box. I been hearing alot about the 4th and 6th order boxes but would like to know which box is best for 2 lvl 5 12s and a 10k. Also i roughly have available space of 40w 36L 16h to work with, in a 99 escalade without 3rd row seating of course. Is it possible to do a 4th or 6th with the space available and would it be worth it to put the lvl 5 in one of those kind of boxes?
