I have a Mach5 MJ 18 going into my tahoe soon so I'm going onto the box stage. Im thinking 5 Cubic feet after Displacment using an 8" sono tube as the port tunned to 30hz. Now my question is, My width is 48 on the truck, so If I made the box 46" wide, can I fire the port at the wheel well? Yould this choke the port? I;m looking to move some pretty decent air.
