___________________________
~For JZX90s, be mindful of sizing when selecting your sub for this project

~Depth size of the Image Dynamics IDQ12 used in the video is 5.91" and it had just enough clearance with the rear glass angle

~The IDQ12's outside diameter is 316.40mm (12.46 in). The larger the diameter the closer the mounting screws will be to the rear glass

~I used Great Stuff foam. Just make sure you get the closed cell variant. The cells are pressed together so air and moisture can't get inside the foam unlike open cell which is flexible and soft

~Because so much air is moving you won't hear an audible difference if it's not 100% sealed but you want to separate the front from the rear as much as you can. When the front waves cancels out the back waves, speaker loading goes down as does SPL output

~Reinforcing/bracing the rear deck is generally done to prevent flex which is another killer of SPL output
