Anywone know where to buy a baffle to protect my speakers from rain that isn't paper thin like the ones found at CT?

It really only needs to be a half moon shape!

Thanks!

 

Most of them are thin so that they can be formed without having big parts of them bunch up (and in a door for example you don't have a ton of room). All you need is a thin piece of plastic whihc can be found at most parts stores.
The XTC one's are thicker but more of a PITA for use in tight doors. They can be found at most car audio retailers.
