Water inside door?

So I have the inside door panels off in front as I've been working on installing new speakers. But today when it was raining hard, I went into the car to check out another issue. That's when I heard "drip...drip...drip..."

I couldn't figure it out until I noticed that the water was coming in off the window and dripping onto the speaker! Luckily I covered the speaker with a baffle for that very reason, but should the inside of my door be getting drips like that? It was a lot and steady. I still worried about the speaker too.

I realize that the door does get moisture inside - hence the drain holes at the bottom. But this seemed excessive. Should I be worried about the seals around the window? Is there something else I should check?

It's an 05 if that makes any difference.

Thoughts??

 

Thanks for the reply. Yes, I agree that there needs to be some protection in there, but are you saying the existing plastic sheet does that? I'm not so sure.

That wouldn't have stopped the water dripping on the speaker magnet. But perhaps you're saying that a new sheet needs to be fabricated when you install new speakers for this reason?

Obviously, I'll need to do something - that just wasn't right. But the passenger side seems pretty dry - I guess that is why I wondered if I should be looking for a leak of some sort.
