Today I was backing out and noticed water poring into my car from the right rear corner of my hatch. The spoiler has started to rot and crack and I'm wondering if water is entering through the holes where its attached. Or is it coming in from where the glass meets the metal on the hatch. Or could it be the seal? The seal looks good. I need to replace the spoiler but I want some suggestions to help fix the leak. I plan on an amp and sub and the last thing I want to do is fry my electronics. Like I said I have no idea where the leak is exactley. Thanks ahead.
