I have two of the 12" kits of oznium, one under each seat.

I zip-tied them to the bar to move the seat, and then there is another bar on the back/bottom of the seat where it moves to adjust the seat. You can do it just right, and it shines pretty nice into the back seat area then too.

Pics are in my gallery, click the link under my name...

 

I just put 15"s right above my feet using zip ties as well. Installation went well, easier than expected and first electrical anything type job i've done. Edit: Ebay -> 27.38$ shipped to my house for 2 15" red neon's

 

could somebody post a pic of where they mounted them under the dash cause i am about to do this as soon as i can get some zipties...
