Abstract

An acoustic system kit for a vehicle speaker and associated methods of installation and manufacture are disclosed. A drum of open-cell foam, preferably several inches thick, having a peel-and-stick pressure-sensitive adhesive backing is cut with two concentric circles to create an outer ring, and inner ring, and a core. The parts are sized to correspond in diameter, respectively, to the front edge, rear edge, and back disc of a particular size of speaker. The inner ring is cut circumferentially to reduce its height to a thin strip relative to the outer ring and drum. Using the pressure-sensitive adhesive, the core is affixed to the inside wall of vehicle door directly behind the door'"'"'s speaker mount, the inner ring is affixed to the rear edge of a speaker to be installed, and the outer ring is affixed to front edge of the speaker. The speaker is then installed on its mount.
