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).
If you want to drive a subwoofer system with your amplifier, you must 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 features a variable sub-level line-out,
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"!).
Note: The EA2350 features two RCA line inputs, and two RCA line-outputs. The line outputs are used
to loop through the RCA signal, if two or more EA2350 are intended to be driven by one RCA stereo
line output signal.
6.2 LOUDSPEAKER WIRE ROUTING
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 an appropriate fuse value since this amplifier is capable of current drain in excess of 150A!
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!
