I just put in 2 Eclipse 12s in the back of the trunk and man do they rattle the hell out of the car. I noticed that the trunk lid doesnt have a liner. Is this true for all Altimas? Do any of yours have the carpet liner? If so, where can I purchase one?

Mine didn't. You have to watch out for the license plate bracket that sits in the center of the trunk lid. ther are 4 nuts that you can tighten, but be careful they can break. Same goes for the spoiler.
