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 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 short circuit.

Use only 30 ampere
ATC blade type fuses.
CA12 uses two 30
ampere fuses.

30A

For High Level input:
We recommend you to connect the remote wire as
described above.
The amplifier will 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 on operation but some plop sound
when switching off.
You do not have to connect any remote voltage
when using Hi level input.

Connect the fuse holder as close to the vehicle
battery + as possible, using AWG5 = 16 mm

2 

or

heavier cable. Use ring crimp terminal cable to
connect to battery +. Apply silicon grease to the
fuse to prevent corrosion.
Use a fuse holder for AGU fuses
like the DLS FH1B. Fuse value
60 A if you use a AWG5 cable.

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.
Be sure to use a rubber grommet or a plastic
insulating tube where the cable passes the firewall
or other places where it can easily be jammed.
Use wire ties to secure to existing cables in the engine
room.
