Connection notes, fig. 4
Negative connection (Ground)
Do not connect the negative line to the negative terminal of
the battery. Lay the negative line to a suitable ground, such
as a chassis screw or the chassis itself. Cut the ground line
as necessary. Then strip the insulation and attach a cable lug
(solder if necessary). Remove the paint of the ground contact
surface and treat with graphite grease (important for a good
ground connection).Screw ground line.
Positive connection +12 V switched (ACC +12 V)
(Ignition)
When connecting the positive line to terminal 15 of the fuse
box (+12 V via ignition) behind the fuse, it will be possible to
turn the system on and off via the ignition. Also, the unit will
automatically switch off after one hour of playback time to
avoid that the battery goes flat. This hour logic will not be
activated when connecting the permanent
+12 V line (terminal 30).
Permanent +12 V connection
(Battery +12 V)
Do not connect the vehicle's positive line !
Lay the red positive wire with a 2.5 mm2 cross section to the
battery (do not route close to vehicle harnesses). Connect
the fuse box to protect the positive line and hook up to the
positive terminal of the battery. If necessary, drill a hole into
the splash wall and use a cable duct as required.
Control wire (Power Antenna +)
The control wire is the switched positive output for external
pieces of equipment such as a
power antenna, maximum load < 150 mA.
Do not connect the control wire to terminal
15 (+12 V switched) or terminal 30 (permanent +12 V).
Control wire (Amplifier)
The control wire is the switched positive output for external
pieces of equipment such as an amplifier or equaliser,
maximum load < 150 mA. Do not connect the control wire to
terminal 15 (+12 V switched) or terminal
30 (permanent +12 V).
Sub Out (Low Pass 100 Hz)
Each amplifier is suitable for single-channel connection.
Lighting connection (Illumination)
Lighting connection for vehicles with adjustable dashboard
lighting (plus-controlled).
Telephone Mute (low)
When connecting a phone, the car radio will be automatically
