Wet Floor When Rains

About a week ago I was driving in rain/snow for about an hour and when I stopped I noticed there was a LOT of water on the drivers side under my floor mat. I thought maybe there was a hole in the firewall where they ran the previous owner's stereo cables through. Well, it rained again last night and when I got in it this morning to go to work, the driver's side floor was wet again. That ruled out the hole in the firewall since it got wet just sitting htere. It's right in the center of the floor board so I'm thinking it's got to be running under the carpet and padding from somewhere and collecting there in the center. Any ideas where this water could be coming from? Maybe a leaky windshield?

Yes, I do have a sunroof. I didn't know there was a drain on them.
I think I found it. The previous owner had installed all kinds of stereo crap in the truck and had run new wires to the door speakers. Well, the seal connecting to the body is not tight against the metal so I think as water ran down there it was leaking in through that. I'll throw a little silicon between there and seal that up good and hopefully keep a dry floor after that. My carpet and padding is SOAKED right now.
I put some black silicon around that seal and it rained two days later and floor was dry so at this point I'm thinking I have the issue solved. So check seal(s) for the wires running to the door. If there's even a tiny space behind the seal, water will get in there.
