Boom Mat baffles protect your car's new speakers from moisture and dirt. Mounted behind the speaker, the baffle forms a mounting seal that also improves sound clarity by reducing panel vibration that could transfer to the speaker.
These baffles will protect your speakers. In many applications we recommend that you cut a hole in the bottom of the baffle, or remove the entire bottom of the baffle, to maintain good bass response while still protecting your speaker from dirt and water damage.
