rhenry, the sup isn't mounted yet. I think i am going to cut out the rest of the Jack, and mount it there w/the sub facing the front of the truck, instead of it facing up towards the ceiling. Is that what you meant?
No...basket up means that the cone (front) of the speaker is pointing into the box so that the magnet and basket are showing. It works well when you mount your speaker in the horizontal plane because you don't collect dust and debris in the cone. And you can point a sub in any direction cause low frequencies are omni directional.
