Notes on speaker connection
• Before connecting the speakers, turn the unit off.
• Use speakers with an impedance of 4 to 8 ohms, and with
adequate power handling capacities to avoid its damage.
• Do not connect the speaker terminals to the car chassis,
or connect the terminals of the right speakers with those
of the left speaker.
• Do not connect the earth lead of this unit to the negative (–)
terminal of the speaker.
• Do not attempt to connect the speakers in parallel.
• Connect only passive speakers. Connecting active
speakers (with built-in amplifi ers) to the speaker terminals
may damage the unit.
• To avoid a malfunction, do not use the built-in speaker leads
installed in your car if the unit shares a common negative (–)
lead for the right and left speakers.
• Do not connect the unit's speaker leads to each other.
Note on connection
If speaker and amplifi er are not connected correctly, "Failure"
appears in the display. In this case, make sure the speaker
and amplifi er are connected correctly.
