This will be the first ported box I have built. I am trying to make a ported box for 2 12" AA Assassins. The AA website says 2 cuft tuned to 32hz. It is going into an suv so the box can be just a basic rectangle. I am kind of new to diy boxes. I have always just paid for someone to do it for me in the past. Can somebody help me design a box??? Thanks in advance!!
