It must be connected to an external 12VDC power supply to function. When you install the SoundExtreme to a battery or a voltage regulator on a golf cart, a boat, a quad bike, a UTV, or another vehicle, you need to make sure that your vehicle battery or battery pack terminal voltage is 12VDC. If the battery terminal voltage is not 12V, you will need a DCDC converter with output 12V. Connecting the SoundExtreme to a non-12VDC power source will lead to a malfunction or damage to the speaker. WARNING: Even when powered off, the SoundExtreme will draw a small amount of power from your battery. To prevent draining your battery when your SoundExtreme or powersports vehicle are not in use for more than 48hrs, we suggest unplugging the SoundExtreme from the battery or adding toggle switch. (Toggle switch sold separately.) Attach the 6ft Power Cable to the 12V Power In SAE Connector (RED). Use Caution: Do NOT connect to 12V Battery if the Power In SAE Connector is wet. Contact may cause electric shock and injury if wet. Remove the 15 Amp Blade Fuse from the Fuse Holder. Use Caution: Do NOT remove Fuse if the Fuse Holder is wet. An improperly fitted cap may cause electric shock and injury if wet. To close properly, push firmly to be sure the cap snaps into place. 4
