Pyle 6.5" Indoor/Outdoor Waterproof Speakers (Pair)

Bought these speakers since the description said they were rustproof, here is what the description states: "PROTECTED FROM ELEMENTS: The mountable speakers feature removable rustproof speaker grill which keeps it corrosion-free and sound distortion-free. It has a marine grade waterproof construction making it safe to use in places w/ heavy water splashes" Well as you can see from the pictures after 5 months of use the grills have rusted. These were installed under my deck so I could listed to music while on patio and I was very happy with them till I looked up at them the other day and saw how bad the rustproof grills have RUSTED! Plus the bracket has also started rusting so it won't be long till they fall off the house. Contacted customer service about the issue and no response after a week. I should have read the reviews closer since it seems the rust is common theme for the bad reviews.
