Air Top 2000 STC Installation under/behind the passenger seat

For standard installations under/behind the passenger seat, we would recommend the flat mounting plate, and for installation into a wooden floor, we would recommend the floor mounting bracket. 

The flat plate will just be a basic plate used to establish a flat mounting surface, it is optional but recommended. The bracket is designed to better fit wooden floor installations - it will have a long flange in the middle for a bit of additional noise reduction from vibration.
