Electrical Connections and Installation

@/<?#&*>@! To avoid the aggravation of costly mistakes and serious damage that could make you feel this way, please carefully read all of the instructions before you begin. Carefully follow all instructions. You’ll be glad you did!

GENERAL RECOMMENDATIONS

•If you’re not confident that you can install the unit correctly, have it installed by a qualified Blaupunkt installation technician.

•Use this unit only with negative ground 12 Volt (11-16 Volt) direct current (DC).

•Be sure to detach the faceplate before you start to connect or install the unit.

•Don’t assume that a seemingly matching wire harness in the vehicle has leads that match the leads of the unit’s wire harness.

•We recommend making and testing all electrical connections before installing the unit. Connect the leads (wires) according to instructions and diagram below.

ELECTRICAL CONNECTION INSTRUCTIONS

1.Disconnect the vehicle battery’s negative terminal before making connections.

2.Connect the speakers and/or external amplifiers (if you have any) following the guidelines in the SPEAKER CONNECTION section below.

3.Connect the blue (trigger output) lead to the amplifier’s trigger input terminal and/or antenna motor trigger input terminal (if you have either or both of these items). The combined total amperage required for triggering the antenna motor and/or amplifier must not exceed 300 mA. DO NOT connect the blue lead to the antenna’s and/or amplifier’s power supply input.

4.Connect the black (power ground) lead to a grounded metal part on the vehicle. We recommend grounding all audio system black ground leads (head unit, external amplifier, etc.) to a common grounding point, preferably a non-painted surface under the instrument panel.

5.Connect the yellow (constant power) input lead to a source of constant battery power, preferably a terminal to an appropriate slot in the fuse box.

6.Connect the red (turn-on power) input lead only after the other leads are connected. Be sure to connect the red lead to a positive (+) 12 Volt power terminal that is energized only when the ignition key is set to the on position or accessory position.

7.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 radio or vehicle.

8.Reconnect the vehicle’s battery.

9.Verify that no fuses have blown.

10.Plug the harness into the unit.

11.Attach the faceplate and test the unit.

Once the connections have been successfully made, you can begin to mount the unit.

SPEAKER CONNECTIONS

The unit’s Dual-Level Fader allows you to fade between the front and the rear channels using either the front and/or rear speaker leads and/or the rear preamp outputs, providing you 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
changer’s harnesses. (See page 11)
• You can use 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.
