6. CABLE ROUTING

6.1 RCA INTERCONNECTS AND REMOTE WIRING

Carefully run the audio signal interconnects, the remote lead and the cable of the remote low pass level

boost unit from the head-unit or dashboard to the amplifier. As mentioned before, the audio signal

cables should 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. Pay attention to connect the stereo interconnects correspondingly, left is 1-CH,

right is always 2-CH (uneven numbers are left, even numbers are right).

Mount the remote low pass level boost unit in a convenient position under or besides the dashboard

and connect the respective cable between the remote device and the amplifier. If your head-unit fea-

tures a variable sub-level output, you can omit the mounting of this additional low pass level remote

control device ("it's up to you to choose, which of both options will serve you better"!).

6.2 CONNECTION OF LOUDSPEAKER WIRES

Once the speaker cables have been routed, turn loose the Allen screws of the speaker terminal bin-

ding 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. Maintain correct

polarity ("+" to "+"; "-" to "-").

6.3 MAIN POWER CABLE ROUTING

Run the positive main power cable ("+12 V") directly from the positive terminal of the car battery to

the amplifier. Make sure to use an appropriate battery clamp, that accepts big gauge cable diame-

ters. Make sure to clean both battery poles from surface corrosion, before connecting the battery

clamps. For protection of your car audio system against electrical fire hazards, resulting from a short-

circuit of the main power cable to chassis ground an ANL fuse holder must be inserted wit-

hin the first 30cm 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 - therefo-

re choose a fuse value of either 150 or 200A. Always keep in mind, that the EA4100-500 amplifier

is capable of 160A max. current drain!

Now you 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 cable must have the same cross-section as the positive power cable. It is recom-

mended to use a corrosion-resistant gold-plated ground clamp to obtain the lowest possible contact

resistance for the chassis ground connection. The contact surface point on the car chassis 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!
