I was planning on running some of these on the roll cage of my blazer...

and still may but I built a few fiberglass subwoofer boxes recently and am thinking about building some fiberglass kick panel pods like this...
For sub duty I would build something that goes on the rear side panels and fires forward.
I have a couple of ported front facing 10" sub boxes that I bought over a decade ago from a guy on CK5 in my storage. They basically replace the side panels and have a magnet cover that goes over the sub. They're super stealthy. If I get a chance I'll try to snap some pics of them this weekend.
