      If your Optimus Amplifier produces no sound, first, ensure your autosound system is on and the volume isn't set too low. Then, check the LEVEL controls on the amplifier. Verify all connections between the amplifier, autosound system, and vehicle are secure. If the amplifier has shut down, turn off your autosound system to let it cool, ensure proper ventilation, and then turn it back on. Also, the amplifier might have detected an input overload, so reduce the autosound system’s volume. Finally, inspect the amplifier’s and autosound system’s fuses, replacing them if necessary.

      If your Optimus Amplifier is producing distorted sound, try reducing your autosound system's output power or volume. Also, check all connections between the amplifier and the autosound system. If the amplifier has shut down, turn off your autosound system and let the amplifier cool, ensuring proper ventilation, before turning it back on. If an output channel might have shorted, take the amplifier to your local RadioShack store.
