Trying to protect your car door speakers from water, dust, and just general moisture? These silicone baffles are a simple and cheap solution. You get two in the pack, and they're designed to fit standard 6.5-inch round speakers (they have an inner diameter of about 5.5 inches and outer of 6.85 inches). They're made from soft, flexible silicone that you can just stretch over the back of your speaker before mounting it in the door. They create a seal that helps keep splashes, condensation, and dirt from getting into the speaker's magnet and components, which can really extend its life. Installation is a breeze – no tools needed really, just pop them on. They're blue, which you won't see once everything's installed. A no-brainer upgrade if you live in a rainy area or just want some extra peace of mind for your car audio investment. Fits most common 6.5\ replacements.
