I was upgrading to an aftermarked deck and had a similar problem to MJAddiction's anyway, while I was in the back I noticed that is smelled kind musty... I put my knee down on the carpet and got my pants wet. The back area is wet from the back of the 3rd row seats to the tail gate, with the wettest area by far being at the very back 4inches where the tail gate is!
How did this happen??
