Ok I'm designing my own box using Google Sketch up and Re Box Calculator, I'm making an box for 4-18" Fi BTLs and was wondering could I have the Tuned Frequency at 20Fb for daily use. I'm going to be using it at shows and was wondering if it would be loud. If it helps its going in an 2007 Expedition EL Firing upward. I dont want to wall it because I'm like being able to look at the rear.
