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 amp 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
output 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. The remote low pass level remote control unit can be
mounted in any convenient position where it can be reached while you drive in your car.
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
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. 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!
