Ive been checking all the leak posts out and no one seems to have my exact problem. I have water collecting up under the rear set (like the battery is swimming) and it moves its way into the rear floor area. Trunk is dry, and so is the front of the car. Any ideas?

Got a sunroof? Rear drain lines may be suspect.

sure do... where do i start?

Check out the link, it should help.

Also, you might want to try a test to see which tube(*) is causing the problem. Take some water and pour it into the gutter tray. You should see water draining out in back of the front wheels and in front of the back wheels. Whichever side you don't see water pouring from, thats the side with trouble. Unless the tube is only partially disconnected or plugged, then you'll have to see which side is draining less than the others.

Okay i have found that at least one of the rear drains are clogged. I hit it with a burst of air and seems to have cleared the drivers side. But, it doesnt have a easy flow yet. I can blow through it but it has some resistance. Is there a part of the hose that gets smaller and would restrict it?

Pull off your rear pillar down side of rear window and tube should run down there into trunk, follow the tube.Also may have to take off roof handle and pull down on your ceiling and right there is your drain tube connection to sunroof.I had the tube partially disconnected and it ran down side of pillar onto floor.

Also, check to see if you may be leaking water past the water deflector for the rear door. This is a great write-up on that by Ddalder.
