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.

Speaker Wiring Notes

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.
