Make sure that you have a good earth connection. A good earth connection will eliminate most electrical
noise problems. A good earth connection requires a tight connection to the vehicle's metal chassis.
The area around the earth connection should be clean, bare metal without rust, paint, plastic, dust, or dirt
for a good electrical connection.
Please Note:
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 un-used speaker outputs to prevent a short circuit.
• Never connect the negative speaker terminals to
earth connection
.
• Never connect to a power source greater than 12V.
