Wow, I am extremely impressed at the quality of this box! I ordered the sealed 12" version and it sits SOLID in the rear door. Slammed the door very hard ten times or so and didn't even budge it. I thought I would need to throw some caulk or liquid gasket in there to hold it in place, but I would be lucky to get the darn thing back out as it is!
If any of you are considering putting a little kick in your ride, this is the place to go for a great buy! Very well made, very reasonably priced, and best of all made by someone in the VX community who knows what they are doing! Thanks Shawn, my vx sounds great thanks to you!
