Wiring
Power and Outputs
Power terminal ( +12V)
+12V REM GND
Remote terminal ( REM )
For RCA cable signal input:
Connect the radio power antenna lead = remote
turn on/off from the car stereo to the amplifier remote
connection. This turns on the amplifier whenever
the car stereo is turned on.
You can either use the built in remote cable in the
RCA cable itself or use a separate cable.
Sometimes a small disturbance may enter the
amplifier coming from the remote voltage , through
the built in remote wire and into the RCA cable.
Thus we recommend to use a separate remote wire
and run the RCA lead separate from remote wire,
power cables and speaker cables.
If there is no remote voltage available from the ste-
reo, you must connect to the ignition key through
the radio or any accessories fuse.

Connect to a good chassis ground. The ground
connection should be clean, unpainted metal to prov-
ide a good electrical connection. Use a wire brush,
a scraper or a piece of an abrasive sheet to clean
the metal. Use a lock washer or two to secure
contact. Protect with silicon grease or by paint
applied afterwards. Use the same cable area for the
ground cable as for the + cable.

Power Light / Protect light
The power light (green ) comes on when
the amplifier is turned on.
The protect light ( red ) comes on
when the amplifier shuts down from
overheating or short circuit.
Fuses
Use only ATC blade
type fuses. CAD11 uses
four 30 amp fuses.
CAD15 use four 40 amp
fuses
40A
For High Level input:
We recommend you to connect the remote wire
as described above. The amplifier will produce soft
on / soft off operation this way. You must set the Hi
level/Low level switch to Low level position in this
case.
In the case that there is no remote voltage available
from the car stereo or you want to simplify the in-
stallation, the amplifier can be turned on/ turned
off by the high level input voltage. This is done
when the Hi level/Low level switch is set to Hi level
position. There is a small disadvantage that this
function gives soft turn off operation but some plop
sound when switching off.
Connect the battery cable to the +12 Volt on the
amplifier. If you want to improve the power capacity
you can add a Power capacitor of 1 Farad in parallel
with the DC input. See the drawing on page 7.
Be sure to use a rubber grommet or a plastic
insulating tube where the cable passes the firewall
or other places when it can easily be jammed.
Use wire ties to secure to existing cables in the
engine room.

Ground Terminal ( GND )
Connect the fuse holder as close to the vehicle
b as possible, using AWG 0 = 50 mm

.
Use ring crimp terminal cable to connect to
b. Apply silicon grease to the fuse to
prevent corrosion. Use a fuse holder for ANL
fuses like the DLS FH2B.
