Your Sub will fall straight through and all is lost.

A little more is fine, but make sure all the screws have somewhere to go.

im planing on making a box for a 15 BL with a height with less then 17 inches tall... no room

That's fine..the internal walls of the box only needs to be 14.250"

You will still clear the basket..

i was also thinking about facing the sub upwards... but i dont know how that would sound... i heard it wouldnt sound so loud. hmmm
