Our speaker wire uses a specially formulated UV-resistant, white polyethylene jacket that provides protection against water damage and allows the cables to withstand extreme weather conditions like rain, snow and high temperatures and incorporate twice the insulation of average cable. If you plan to bury the cable, OSD recommends you bury it 4-6" underground so that it''s not visible nor pose a danger of somebody tripping over it. Our speaker cable is ideal to use in direct burial applications. As for the gauge, for runs up to 100 feet for background music, 16-gauge will be fine. If the run is approaching or exceeding 100 feet, we suggest 14-gauge wire. Add Volume ControlsVolume controls can be a great addition to a system providing both proper impedance matching and more hands-on local control of the volume in the listening area. We offer a great selection of outdoor volume controls to choose from!Extremely DurableOSD outdoor speakers are developed with harsh conditions of the outdoors in mind. Our rock speakers use only non-water-absorbing materials and won''t absorb any water. This is critical in winter so it won''t freeze and crack. The shape is designed to withstand large amounts of pressure, extreme temperatures and moisture. Remember though, outdoor speakers are an investment, so take care of them. Storing them away from extreme weather conditions will only lengthen the time you will get enjoying outdoor speakers. These rock speakers utilize weather-resistant components for years of trouble free performance.
