4. WIRE ROUTING AND CONNECTIONS
4.1 MAIN POWER WIRES
Run the positive main power cable („+12 V“) directly from the positive terminal of the car battery
to the amplifier. For protection of your car audio system against electrical fire hazards, resulting
from a short-circuit of the main power cable to chassis ground
a main fuse holder must be
inserted within the first 30 cm of the positive main power cable.
The applicable fuse value
must be matched to the limitations of your main power cable AND the current draw of the ampli-
fier – therefore choose an appropriate fuse value.
Attach the ground cable to the amplifier.
In most cases it will be best to keep the ground cable
as short as possible, i.e. to find a chassis contact very close to the amplifier. The ground power
wire must have the same cross-section as the positive power cable. The contact point where the
ground wire is attached to, must be solid and clean, i.e. free from rust or paint!
Tighten both power input terminals of the amplifier, and double check for perfect fit of both main
cable leads!
4.2 RCA & REMOTE WIRES
Carefully run the audio signal interconnects, the remote wire and – if applicable - the cable of
the low pass level remote control from the head-unit or dashboard to the amplifier. As mentioned
before, the audio signal cables should always be routed completely separate from the power
cables. Connect the remote (turn on/turn off) lead of the headunit to the respective REM terminal
of the amplifier. Now you can connect the RCA interconnects to the respective outputs of your
head-unit and to the inputs of the amplifier. Pay attention to connect the stereo interconnects
correspondingly,
left

1CH
,
right

2CH
a.s.o.
Note:
You can install the remote low pass level remote control in a convenient position under or
besides the dashboard.
4.3 LOUDSPEAKER WIRES
Once the speaker cables have been routed, turn loose the screws of the speaker terminal bind-
ing posts and – after inserting the stripped speaker cables – re-tighten the screws. When baring
wires for connection, remove approximately 6-8mm of the insulation and after axially twisting
the wires, insert the bare ends into the corresponding speaker terminal output on the amplifier.
Close the electrical circuit by inserting the main fuse and reconnect the negative battery pole.
Now switch on your head-unit. The green OPERATING LED of the amplifier should light-up. If
the LED lights up red, your installation is wrong! Immediately turn off your head-unit and care-
fully re-check all wiring steps!
