I am putting them in a 2003 dodge durango I have bout 14 cubes to work with at the most. I don't no if I should do ported or sealed I would be going for spl competition. Some people tell me sealed and I would think ported for more air, but I was wondering what the lowest I could wire 6 12" kicker cvr D4 down to. If someone can help me figure out the best enclosure and what they can be wired to that would be a lot of help thanks.
