Anyone planning on doing an aftermarket stereo system in the truck? It's something I wouldn't mind doing but.....where are installers going to run amp/sub wiring? In my past cars, it's been under the floor carpeting. Obviously, since the FJ has no carpet...whats the next option? Maybe under the rubber floor? Does anyone even think this will be possible? I'd imagine the rubber flooring is glued down or something. Any input from people who have seen it in person?
