protection circuits by covering the heat sink or
connecting improper loads.
• If your car is parked in direct sunlight and there is
a considerable rise in temperature inside the car,
wait until the unit cools down before use.
• For safety, keep the volume of the unit at a
moderate level that allows you to sufficiently hear
the sound of traffic outside the vehicle.
• Do not splash liquid onto the amplifier.
