4. WIRE ROUTING
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 amplifier – there-
fore choose an appropriate fuse value.
Attach the ground cable to the amplifier. In most cases it will be best to keep the ground
cable („-12V“) 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 to the respective input terminal of the amplifier and to the remote out-
put of your head-unit. 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 corre-
spondingly,
left is 1CH, right is always 2CH a.s.o.
If you want to drive a subwoofer system with your amplifier, 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 binding posts
and – after inserting the stripped speaker cables – re-tighten the screws. When baring wires for con-
nection, 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. Maintain
correct polar-
ity („“ to „“; „„ to „„).
Close the electrical circuit by inserting the main fuse. 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 carefully re-check all installation steps!
