Notes on Installation  
• Disconnect negative battery terminal before starting installation. Consult the vehicle’s  
owner’s manual for proper instruction.  
• The unit is designed for a 12 Volt DC negative ground operation system only. Before  
installing the unit, make sure your vehicle is a 12 Volt DC negative ground system.  
• Mark the polarity of the existing speaker wires before disconnecting the old unit.  
• Be sure to connect the color coded leads according to the diagram. Incorrect connec-  
tions may cause the unit to malfunction or damage the vehicle's electrical system.  
• Make sure all the connections are completely correct before turning on your unit.  
• When extending the ignition, memory backup or ground cable, use diameter of 0.75mm  
(AWG18) or more automotive grade cable to avoid wire deterioration or damage to the  
wire coating.  
• To prevent short circuit, never put or leave any metallic object inside the unit. If you  
smell or see smoke, turn off the power immediately and consult your dealer.  
• Insert the unit until it is firmly locked into mounting sleeve, otherwise it may fall out.  
Be careful not to drop or shock the unit, it may break or crack because it contains glass  
parts.  
• The unit is only designed for use with 2 speakers. Do not ground negative speaker  
leads to the chassis ground.  
• Do not open the top or bottom cover and do not install the unit in a place where it  
is exposed to direct sunlight (including faceplate), high heat, humidity, moisture, or  
dust.  
• The faceplate is a precision piece of equipment that contains sensitive electronic com-  
ponents. Do not subject it to excessive shock.  
• When replacing the fuse(s), the replacement must be of the same amperage as shown  
on the fuse holder.  
• Do not block vents or heater panels. Blocking them will cause heat to build up inside  
and may result in fire.  
• After completing the installation and before operating the unit, reconnect the battery.  
Then press the (RES) button with a pointed object, such as a ball-point pen to set the  
unit to its initial status.  
• Do not touch the terminals of the faceplate or of the unit.  
• If you have difficulty installing this unit in your vehicle. Please contact your dealer.
