I am taking out the "jump seat" and building a custom center console that start where the factory cup holders are now (remove them and fill in that area) and run back to the end of the jump seat. I will build up the back to have a storage/arm rest and under that I will have a box.. I think one 10W7 as well, firing to the back of the cab.:$:depends on how you like to listen to your music... The 10W7 would be really loud LOW bass. The two 10W6's would be be louder, just might not hit as deep. You def cant go wrong with either. Where are you going to put the box? under the back seat i assume. if you went with the single, you would still have some storage room
