WIRING DIAGRAM

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.
Yellow Memory Backup
Connect to electrical terminal always supplied with power regardless of ignition switch 
position.
Orange Remote
Connect to Auto-antenna or power amp control wire/remote  connection. Maximum cur-
rent 300mA 12VDC. (Low Current)

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.
