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. 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 attempt to 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.
