i got mine facing up. i think it sounds better :headbang:

I'm gonna try mine out facing down with small legs/spacers to keep at least a 1 inch space between the floor and face of sub. I have seen a lot of home stereo surround system with the sub that way figured I'd try it out in the truck. Seems to me that it would distribute the bass well and sound good. I'll let you know how it goes when I finally do it.alright thanks for the reply. Any other opinions?
