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 12Volt DC negative ground operation system only. Before Installing  
the unit, make sure your vehicle is a 12Volt DC negative ground system.  
Be sure to connect the leads according to the diagram. Incorrect connections may cause the  
unit to malfunction or damage the vehicle's electrical system.  
Be sure to connect the negative (-) speaker leads to the negative (-) speaker terminal. Never  
connect negative (-) speaker leads to chassis ground.  
The unit is only designed for use with 4 speakers. Do not combine output for use with 2  
speakers. Do not ground negative speaker leads to the chassis ground.  
Make sure all of the connections are completely correct before turning on your unit.  
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 (RESET) button with a pointed object, such as a ball-point pen to set the unit to its  
initial status.  
Before You Install  
Automotive audio equipment installations can be troublesome at times, even to the  
most experienced of installation technicians. If you are not confident working with  
electrical wiring, removing and reinstalling interior panels, carpeting, dashboards or  
other components of your vehicle, please call your dealer in order to have the unit  
professionally installed.

Wiring Connections  
Make sure that you have a good chassis ground. Good ground connections will eliminate  
most electrical noise problems. A good chassis ground requires a tight connection to the  
vehicle's metal chassis. The area around the ground connection should be clean, bare  
metal without rust, paint, plastic, dust, or dirt for a good electrical connection.

Speaker Wiring Notes  
Follow the above wiring diagram to install the head unit with new or existing speakers.  
This unit is designed for use with four (4) speakers with an impedance between 4 ohms  
to 8 ohms.  
An impedance load of less than 4 Ohms could damage the unit.  
Never bridge or combine the speaker wire outputs. When not using four speakers, use  
electrical tape to tape the ends of the unused speaker outputs to prevent a short circuit.  
Never ground the negative speaker terminals to chassis ground.
