ok, so i have my subs and i have figured out the amp to power them. now i need to figure out if the box that i have will be sufficient or if i am better off with a different design. the following is as much useful information as i can think of, but if you need anymore just ask. also haven't been able to find detailed specs on the speakers, so i don't know fo, qes, xmax or anything like that, that's why i need your help. haven't found anyone that has that info either, so hopefully you all can still throw me some input. thanks.
