[QUOTE="THATpurpleKUSH, post: 8631087, member: 615398"] You want to know what the res freq of the vehicle is, not so much the box itself. You design the box to peak at the vehicles res frequency to maximize the transfer function of the vehicle. A 3:1 ratio 4th order would be enormous for 2 18s. Make sure you have the room for it.
