DO NOT DISCONNECT WIRES
AT THIS TIME!
Mark Polarity of the Speaker Wires
Marking the polarity of the speaker wirers will make it easier to connect the existing speakers to your car radio. Consult wiring diagram
of existing head unit before disconnecting any wires. If you are not positive of the polarity of the existing wires from the speakers to the
head unit, install new wires.
1. While the old unit is playing, disconnect the wires from one speaker.
2. Take a length of masking tape and fold it around the wire so it forms a flag.
3. On the masking tape mark the polarity of the speaker wires (+&-), as well as left or right, and front or rear.
4. Double check that you marked the first speaker correctly by checking that the speaker wires are the same at the head unit.
5. Repeat this procedure for all of the speakers.
6. Mark the power, ground, and any other wires also.

WIRING DIAGRAM
General Wiring Notes:
Make sure You have a good chassis ground. Good ground connection 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 ground connection.
Black Ground
Connect to vehicle body/chassis. Make sure you have a good chassis ground. This will eliminate most electrical noise form the motor
and alternator. A good chassis ground requires a tight connection to ground. The area should be free from rust, paint or any form of dirt.
Red Ignition
Connect to car ignition switch for main power supply of the unit.
Yellow Memory Backup
Connect to electrical terminal always supplied with power regardless of ignition switch position.
Blue-White Remote
Connect to Auto-antenna or power amp control wire/remote connection. Maximum current 300mA 12VDC. (Low Current)
Green (Hand Brake - Ground)
Connect this wire to the hand brake wire of your car so that the display will be on only when the car is fully stopped.
Purple-White (Rear Gear - VCC)

Speaker Wiring Notes:
Follow the above wiring diagram to install the head unit with new or existing speakers.
1. This unit is designed for use with four (4) speakers with impedance between 4 Ohms to 8 Ohms.
2. An Impedance load of less than 4 Ohms could damage the unit.
3. 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.
4. Never ground the negative speaker terminals to chassis ground.
