Well, I did some digging and looking with a flashlight.
There are two drain tubes behind each kickpanel where the front speakers are. But the suprising thing I found was the tubes were slash cut and not directly plumbed directly to the outer drain holes. It's a weird design I must say. You'll want to check for two slits in the very front part of your rocker panel and make sure they aren't clogged.
My central lock relay had shorted out from filling with water. If your central lock isn't in the factory location with the factory metal bracket, I would suggest not having it located at the very bottom as it can get wet in very heavy down pour situations. I had taken it off and moved it earlier so that I can fit my crossovers in the same spot.
Also, check to make sure your door grommet covers(rubber square pieces) in your door jambs are nice and tight. This is where I suspected a lot of my water found in the kick panels to have come from.
There are also two drain tubes located at the rear behind your trunk panels. These lead into the rear sidemarker assemblies which exit towards the bottom of the car. Pull them out and make sure they aren't clogged. Also make sure they are secured all the way in. I found one of mine loose hanging partially out.
