On the speaker

SQL Soundwave is such a unique product that allows you to use it in multiple ways. It can be installed on top of the speaker, creating a baffle between the door panel and the speaker. The unique feature of Soundwave is the way you can cut and install on various speaker sizes, prevent rattles in areas that need some form of insulation and more. Soundwave is a rubberized foam that is fully waterproof and installation could not be easier using a 3M peel and stick adhesive.
