So many people have told me that a 4th order is the way to go. Never had one. So when attempting to design a 4th order how do you know the sizes to make the enclosure? How many cubes for the sealed section? how to design the port?
Here is some of my info
Kicker Solo X 18"
02 Monte Carlo with about 7 cubes to work with.
Might have to design the box to dip into the spare tire area, for a extra few inches of space.
