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 connec-
tion 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 dia-
gram 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.
