A few ideas I had thought of are to remove the cabin fan and plenum and seeing how much room I have in there. A cheaper more practical idea is to but a smaller sub like an 8 or so bazooka tube. Stand it up or lay it down in the corner of the cab. I do have a kicker 10" in a truck box that doesn't fit in the truck that I'm thinking of trading one of my coworkers for a bazooka tube he isn't using. No luck yet. Sorry, no pictures. Truck don't run right now and filled with engine parts and tools. Among other crap. Lol.
