Hey guys im gonna be starting my build next week or so. This is the first c-pillar wall that i have done. Yes it has to be a c-pillar wall because thats what i want. The subs are 2 DC Lvl 3 m2 18's (stock). Power will be 1 Skar 2500. Will be changing or adding another amp later on. Ive planed on having 15 cubes internal (thats 3 cubes over spec i know) tuned to 28hz. The main goal for this build is just being loud and moving as much air as possible. I do not care about numbers. Im pretty able to do this build myself i just need some help with a few things as i said this is my first time doing this. Ask questions bash me idc as long as i learn from it. Thanks guys.
