Notes on speaker connection
• Use speakers with an impedance of 4 to 8 ohms, and with adequate power
handling capacities. Otherwise, the speakers may be damaged.
• Do not connect the terminals of the speaker system to the car chassis, and
do not connect the terminals of the right speaker with those of the left
speaker.
• Do not connect the speakers in parallel.
• Do not connect any active speakers (with built-in amplifiers) to the speaker
terminals of the unit. Doing so may damage the active speakers.
Therefore, be sure to connect passive speakers to these terminals.
