Hey Everyone, I just got done installing the factory subwoofer in my tc today, and I got to say that its perfect for people that just want some extra non-neighboorhood shaking base. Installation is also fairly simple. I have one problem, I put together the back interior after connecting the sub, and right behind the rear seat, theres a gap now, I'm pretty sure I did something wrong. I can see the plastic part that snaps on to the metal. I started with the plastic part, then I put the cargo cover on top of that and lined it up with the holes so I can put the hooks on. What part am I missing?

^^^^ My post proves that the sub installation is cake because I'm horrible at installing things and I only had minor problems .
