Well, you can but you'll probably lose some SQ unless you get creative with your enlcosure. What I've found is that you almost always need to build a ported box in a truck but that takes a lot of space compared to a sealed enclosure. I can't seem to find pictures but before my wife took over my truck, I had 2 Directed Audio 12" CompX subs in separate enclosures. They were only about 5"x13"x20" and I had them reversed mounted. The enlcosures filled the whole area between the sides of the seat braces and the hump. The magnet went up into the bottoms of the seat since there isn't much there. Man did it ever thump!
