Using your DS18 HYDRO 4 wakeboard tower speakers is easy. First, find a suitable location on your vehicle, preferably on a 1.5 - 2 - inch tower bar. Then, use the redesigned clamping system to securely mount the pods. Make sure to connect the speakers to a power source that can supply up to 150 watts max and 50 watts RMS per speaker. When using, keep in mind that these speakers are great for smaller vehicles with vibration, but they can be used on any vehicle. Avoid exposing the speakers to extreme weather conditions for long periods. For maintenance, regularly wipe the speakers with a soft, dry cloth to keep them clean. Check the clamping system periodically to ensure it remains tight. If you notice any issues with the sound quality or the clamping, refer to the owner's manual or contact customer support.
