Wiring Connections
Make sure you have good chassis ground. A 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 electrical connection.

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 unused
speaker outputs to prevent a short circuit.
• Never ground the negative speaker termi-
nals to chassis ground.
