Universal plastic speaker rings serve as a practical mounting element when installing speakers in vehicles where original mounting adapters are not available or in cases where it is necessary to adjust the depth or diameter of the hole for optimal speaker placement. These rings are made of strong and durable plastic that resists vibrations, moisture and temperature differences, which ensures stable and long-term mounting of speakers without sound distortion. The universal design allows for wide use across different types of vehicles and speaker brands, whether it is installation in doors, rear shelves or other non-typical positions. The rings help to level out unevenness of the mounting surface, adapt different diameters (e.g. 130 mm, 165 mm, 200 mm) and also eliminate resonances that could negatively affect acoustics. Thanks to their versatility, they are an ideal choice for all car audio enthusiasts who are looking for a flexible and high-quality mounting solution regardless of the specific car model. Choose from a variety of shapes, heights and variations to achieve a professional installation and clear sound without compromise!
