Water leaking into the passenger side... help?

Cell

I washed my car today and noticed that after washing it, there was a small puddle of water on my rubber mat. It is coming through some how and I cannot figure it out.

I am certainly not going to dump more water to try and find out. This is why I came here to see if anyone else had this problem?

The panels under the hood has been removed before so I can install my turbo kit and gauges. The panels were put back as is and now I have a leak. As far as I know, when it rains it doesn't leak into the car. I believe it is coming through the air vents under the hood but is that possible?

Any help is appreciated. Thanks
