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.
You can either use a crimp fork terminal or insert
the cable directly into the amplifier terminal. If there
is no remote voltage available from the stereo, you
must connect to the ignition key through the radio
or any accessories fuse.
Connect the fuse holder as close to the vehicle
battery + as possible, using AWG 8 = 10 mm
2
or
heavier cable. Use ring crimp terminal cable to
connect to battery +. Apply silicon grease to the
fuse to prevent corrosion
Connect the battery cable by a crimp fork terminal
( spade ) to the +12 Volt on the amplifier.
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 ty-wraps to secure to existing cables in the
engine compartment.

Connect to a good chasis 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.

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
installation, 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.
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 a short circuit ( speaker
failure)
