I've got two new KFC-XW12's that are looking for a new box. I have an r750 amp to power them and it'd going in the back of an 1997 Subaru outback sport. I just want some suggestions for what type of box to build, I have already purchased a 4x8 sheet of MDF board. I listen to dubstep, metal, irish rock, classic rock, really i listen to just about everything, I had a bandpass box with a pair of RF 10in subs and I loved the way that it rumbled my car, however I do realize that that can slowly ruin your subs. So, suggestions?
