I can't say whether it is normal or not, but the same happened to me...

Washed the car and then went back to working on my stereo install...water droplets all around the interior of the door, on the back of the speaker and the crossover.

 

its like a camelback bladder in your door...just buy the tube straw and you'll never be thirsty ...or need a cupholder ever again!

 

Where did you mount your crossovers that they are getting wet?

Ron,

Inside the door panel, behind the speaker.

 

I have the same problem. I've actually had water freeze on my speakers over night. I'm waiting for these baffles to arrive to hopefully prevent this.
