Leaking Speaker

Hi

I've just been reading Hewey's thread about his TD5 leaking, and it's reminded me about mine.
I've noticed that the rear speaker in the boot built into the pillar (drivers side), has a streak of water coming from it and it looks like it definetely coming from the speaker hole!!!
Any ideas on whether theres a drain tube up in there somewhere? or anyone experienced the same?

O and the speaker doesn't work and hasn't for a while, i'm assuming the waters knackered it!!!

Thanks

Don't want to spook you but could it be tears of sorrow.
