2010 Ram 1500 CrewCab water leak HD

UPDATE: I found the source of the leak.. the 3rd brake light above the cab was not sealed properly. Found the back bench seat in my 2010 crew cab soaked after a strong thunder storm last night. all the windows were up and the doors were closed. I couldnt find moisture anywhere but the seats.. Got my amp and wires wet, Im letting them dry before I test them. Other then the damange to the amp, I am worried about possible mold in the back seat, and rust which ive already found some back there and the truck is 4 months old. BTW in the video when I point the camera to the rear sliding window I know it looks wet, but thats just little imperfections in the tint job I did on that window.
