Hi to you all.
I take down the rear box for the speakers, and change them.
I put it all bac up to the roof OK, and now the water come out of  front
of  box when the air condition is on.
I check the hose, and are hook up to  black pan in bottom.
I see all kind of black foam all over when box  down, and I clean up.
What it is?
Now it gone.

Any of you know about foam ?

Good morning to all,

Fred
