so i need help with a box design, the box is for a friend going in a civic hatchback. He has 2 12" Alpine type r's.
31 inches wide
20 inches top depth
20 inches bottom depth
13.5 inches tall are the measurements he gave me and wants it tuned to 32hz. He was looking for subs mounted on top and port either on top with subs or firing towards the hatchback. The dimensions seem pretty small to me but let me know
