OK. now how far about should they be from bottom of hatch,like where that plastic pannel is? Where would the best port loction be one on each side or both in the middle bewteen the sub's, or would one port be better? also should the port be in the front side of box(front of car) or under the hatch at back of car? Also to get the air space I need the box would actuly be like 2 boxes sitting on top of each other,That's so I can uses upper well and lower well for more cube's. will the lip's on eather side of box(for the lower one being smaller) change the tuning or sub out put? Thank's for all the help this place is great!
