blade type fuses when
replacing a blown fuse.

Connect the fuse holder as close to the vehicle
b as possible, using AWG 4 = 21 mm

power cable. Use a ring crimp terminal cable to
connect to b. Apply silicon grease to the
fuse to prevent corrosion. The AWG4 cable can
use an 80 Amp fuse, if the cable is smaller, the
fuse value must be lower (see table on previous
page).
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.

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 ( spea-
ker failure)
Fuses
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 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.
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.
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
automatically when the head unit is turned on. There
is a small disadvantage that this function gives soft
turn on operation but some pop sound when
switching off.
GND REM +12V Fuse
A cable up to AWG 4 fits directly in the amp
12 V terminal, tighten with the hex screw.
Be sure to use a rubber grommet or a plastic
insulating tube where the cable passes the firewall
or other places where it can be easily jammed.
Use wire ties to secure to existing cables in the
engine compartment.
