3. ELECTRICAL WIRING
Especially the music signal cables (RCA interconnects)
should be kept far away from any potential sources of el-
ectrical interference i.e. electronic vehicle management
systems (engine computers, relays etc.) fuel pumps, wi-
ring harnesses etc.!
3.1 RCA INTERCONNECTS / REMOTE
LEAD
Carefully run the RCA audio signal interconnect(s) and
the remote switching cable from the head-unit to the am-
plifier. The audio signal cables should be routed comple-
tely separate from the power cables. Use only double or
triple shielded quality cables!
Connect the remote wire lead to the remote output of the
head-unit and to the remote input terminal of the ampli-
fier. Finally connect the RCA interconnect cable(s) to the
respective outputs on the head-unit and the RCA inputs
of the amplifier.

3.2 LOUDSPEAKER CABLES

Connect the loudspeaker wires to the speaker terminals
of the amplifier. Use good quality wires of 2.5mm
section. You will need a set of Allen wrenches for the
connection of the wires!
When baring wires, remove approximately 6-8mm of the
insulation and after axially twisting the wires; insert the
bare ends into the corresponding speaker terminal out-
put on the amplifier. Be sure to follow correct polarity
("+" to "+"; "-" to "-"). Tighten the terminal screws on
the amplifier.

3.3 CONNECTION OF POWER CABLES

Run the positive power cable ("+12 V") directly from the
positive terminal of the car battery to the amplifier.
Make sure the power cable makes good contact to the
battery; i.e. use an appropriate battery clamp that ac-
cepts big gauge power cables! For protection of your car
audio system and your entire car against electrical fire
hazards from a short-circuit of the main power cable
with chassis ground, you must insert a main fuse (hol-
der) within the first 30cm of the battery. The fuse type/va-
lue should be matching the limitations of your main po-
wer cable and the requirements of your car audio system.
Preferably a minimum of 80 Amperes with this amplifier
and an appropriate power cable cross-section.
Now you route the ground cable to the amplifier. It is 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 cable must have the same cross-sec-
tion as the positive power cable. It is recommended to
use a corrosion-resistant gold-plated power ring or a
massive ground clamp between the ground cable and
the chassis ground point. Keep in mind that audible in-
terferences and problems originating in the power supp-
ly of the amplifier, are mostly based on a bad ground
contact. So a good (and clean) grounding to the vehicle
chassis is absolutely crucial, to obtain best performance
of your amplifier.
