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).

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.When
mounting the anti-interference choke coil, wrap in foamed
plastic.
