RetroSound RetroPod Surface Mount Speaker Modules are manufactured from sturdy yet easy to trim ABS plastic and allow you to add a new speaker location on any flat surface including rear package trays, door panels or kick panels. The angled speaker mounting design allows the sound waves to travel where you want it, directly to you and your passenger's ears. RetroSound RetroPods are molded in black but can covered in vinyl wrap or painted to match your interior's color scheme. Speaker grills are included and a rotary cutting tool is required to trim out the speaker hole pattern you require. Best of all RetroPods can be purchased without speakers or with your favorite RetroSound speakers to match the rest of your custom RetroSound system.
