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.

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 ( spea-
ker failure).
Turn off your audio system to reset the
amplifier if the red protect light is
turned on. If the red lamp doesn’t turn
off, contact your local dealer for
advice.
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.
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 installation, the amplifier can be turned on/ tur-
ned 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.
A cable up to AWG 4 (21 sq mm) fits the amp
12 V terminal if using DLS
FT22
fork terminals.
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.

connect to b and a fork terminal to
connect to the amp terminal. The AWG4

smaller, the fuse value must be lower (see table
on previous page).
