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 ground (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 amplifiers) 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.
