tremendous flexibility in configuring your speaker arrangement:
• You can connect a speaker (regular, co-axial or tri-axial speakers or component speaker system,
all hereafter referred to simply as “speaker”) to each of the units’ four pairs of speaker leads.
• You can connect the 2 RCA preamp outputs to multiple external amplifiers and power multiple
speakers or speaker systems through the amplifiers. (Blaupunkt amplifiers and speakers
available separately). To add front preamp output, purchase Blaupunkt part 8634494218, which is
included in the CDC-A05 and CDC-A071 changers harnesses (see page 11).
• You can use a either or both of these two methods.
Connecting the Speaker Leads
To prevent short circuits or serious damage to the unit and/or speakers:
• Connect the speaker leads only as indicated in the wiring diagram. Disconnect the vehicle
battery’s negative terminal before making connections.
• Only use speakers that have impedance ratings of 4 ohms or higher and have power-handling
capabilities greater than the receiver’s stated power level.
• The unit’s internal amplifier is designed to handle a 4-ohm load on each pair of speaker leads.
• DON’T connect two speakers to a single pair of speaker leads (“in parallel”) unless both speakers
each have at least 8 ohms impedance.
• DON’T connect the left and right speaker leads to each other or to the same speakers.
• DON’T connect the front and rear speaker leads to each other or to the same speakers.
• DON’T connect the negative speaker leads to each other.
• DON’T connect the positive speaker leads to each other.
• DON’T connect any active speakers (with built-in amplifiers) to the speaker leads unless their
owner’s manuals specifically state that this is O.K.
• Cover the ends of any unused leads with electrical tape. This will prevent them from touching the
vehicle or each other and causing a short-circuit and damage to the receiver or vehicle.
Connecting the Pre-Amp Outputs to External Amplifier(s)
To prevent short circuits or serious damage to the receiver, amplifier, and/or speakers:
• Follow the amplifier’s instructions on how to connect the unit’s preamp outputs to the amplifier(s)
and connect the speaker(s) directly to the amplifier.
