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
