Don't have any pics right now, of the speakers mounted up, I'll see if I can find them. I've got the whole truck pulled apart right now and I just spent a half hour looking for the speakers, can't find them but if I run across them I'll post it.
Oh, been thinking bout that, you mean Water Proof right??? Nope, nothing fancy, just taped some Visqueen Vapor Barrier above it to deflect any water just like they do in the new cars and trucks.
