I find it interesting it was made in Hungary!
Zex, Reus Systems did some audio work on my car and I have a 10" sub in the factory location and another 10" removable sub enclosure in the footwell. I believe the factory sub is an 8" one. The removable enclosure is great as it allows me to keep that whole footwell space if I want to have the kids in the back (we have the 3rd row) or just need some extra space for something. There is a quick release cable to the footwell sub that is super easy to connect and disconnect.
It can definitely thump now, but two 12"s in the footwell with the side areas for ports would be heavy duty!
