I am thinking of doing a subwoofer install in my 2.5 roadster, but the options seem limited. Has anyone ever tried creating a subwoofer enclosure using the area under the door sills/side panels? The space between the carbon fiber body panels and the roadster frame/tub seems like an ideal space, but I'm not sure if there are any drivers small enough to fit in there. The empty space would be stuffed with subwoofer filler material. The overall strategy would be to go small, but create left and right subs for an improved effect. Is this a crazy idea?
