Spoke with JL Audio last week. They again took the car for sound tests. I was advised that they will further "tweek" the box as they want more air space for lower sounds. The mold for my box was made fitting 2 molds(top & bottom) together making the box. From this mold they plan on making the all in one box. They rejected the idea of putting the sub in the center console. I expect to hear from them again in about 3 weeks.
