"A vehicle endures all weather conditions — wet, dry, hot, and cold. That means your speakers must, too. Moisture causes speaker damage. If you find your speaker performs poorly in certain weather conditions, you may try a set of speaker baffles. These soft foam surrounds not only seal out moisture, they also protect the speaker against dust and dirt, and block road noise at the same time. If your speakers perform well, you can still use speaker baffles to prevent future environmental damage."
Sounds to me like the baffles work two fold: better sounding and weather proofing. All I am looking for is the weatherproofing. So why is using a ziploc bag to protect against the dirt/debris/water such a bad idea if thats all I am worried about?
As long as it doesn't make it sound worse, I still think its a pretty decent idea. Any other suggestions?
