Water and dirt may wet your aftermarket-installed car door speaker over time if left unprotected. This often results in rusted baskets (stamped steel), unglued surrounds and spiders, and; more than likely, eventual voice coil rub caused by debris in the gap. It is for this reason that responsible, professional installers never ever skip this important step, especially for high end drivers.
Prolong your speaker's life span by keeping them dry. You'll be surprised how long they can last if properly cared for.
Easy to install and easy to retrofit to an existing, previously mounted aftermarket speaker. Pre-drilled holes make mounting a piece of cake. This simple item will save you (end user) thousands of pesos in labor and material costs, not to mention the preservation of your speaker's resale value.
