I am replacing the sub in a 07 Lexus GX470. In the process of removing everything I found this little section of carpet wet. It's the right rear corner. I can see that white tube so that must be a drain?? How would you go about finding this leak?
How Should I Start To Find This Leak?

Fold down the back seat(s) and take up as comfortable position as you can in the rear hold. Have a helper simulate heavy rain with a garden hose while you look for the leak's origin. It can be very tough - especially with a small leak.
FWIW, I'd also try to ensure that drain tube is clear. Find it's end under the vehicle and apply light blasts of compressed air (or suction if it's clogged from below).

I seems to be a sunroof drain tube, the question is is the water not going down the tube or is it running down the outside of the tube because it is clogged or is it coming up from underneath. I usually run an old speedometer cable down them turning it as you push it through, be careful, if you use too much force or too much compressed air to clear a blockage you can knock the tube of the sunroof fitting. That could be a big job.

Outdoor. under trees. has sunroof. goes through car washes
Trav, is that white tube the end of a drain tube? I will have to remove so much stuff to see behind it.LOL
As trav noted, sunroof drain is clogged.
This is the likely culprit. I would start by opening the sunroof and vacuuming out all of the dirt and debris you can find. Then, locate the (4?) drain holes in the sunroof's recessed cavity perimeter and clear out what you can reach with a 12" nylon tie wrap of the appropriate diameter. Pour some water down each hole to verify it flows freely and doesn't back up while focusing on the corner nearest the leak. If the water backs up and pools in the sunroof area, take a long piece of weed trimmer line and run it through the drain tube. Flush with water and repeat as needed. I agree with @Trav that you want to avoid using compressed air because of the potential for dislodging the tube which may require removing the headliner to reconnect.
Outside of the sunroof drain suggested, inspect and manually clean around the inside of the hatch and hatch jamb (with hatch open) with a good brush and some judicious use of hose water. You would be surprised how much junk over time will cake in those areas and might prevent proper drainage. Clean your sunroof the same.
The front drain holes are fine. I think I need a little elevation to check the back. I have no idea where they are. However, I think I found the culprit. The right corner seal at the top of the rear door was not glued down. It has some black glue holding most of it down. I'm gonna use some "Black Super Weatherstrip Adhesive" from 3M. AFTER....it dries
