POWER CONNECTIONS
The CS amplifiers are capable of delivering
extremely high power levels, and require a
heavy-duty and reliable connection to the
vehicle’s electrical system in order to
perform optimally. See Figures 1, 2 and 3 for
connection location. Please adhere to the
following instructions carefully:

Ground Connection
Connect the amplifier’s Ground (GND)
terminal to a solid point on the vehicle’s
metal chassis, as close to the amplifier 
as possible. Refer to the chart below to
determine minimum wire-gauge size.
Scrape away any paint from this location;
use a star-type-lock washer to secure the
connection.

Power Connection
Connect a wire (see chart at right for
appropriate gauge) directly to the vehicle’s
positive battery terminal, and install an
appropriate fuse holder within 50cm (18") of
the battery terminal. 

Do not install the fuse

at this time.

Route the wire to the

amplifier’s location, and connect it to the
amplifier’s Positive (+12V) terminal. Be sure
to use appropriate grommets whenever
routing wires through the firewall or other
sheet metal. 

Failure to adequately protect

the positive wire from potential damage
may result in a vehicle fire.

When you are

done routing and connecting this wire, you
may install the fuse at the battery.

Remote Connection
Connect the amplifier’s Remote (REM) 
terminal to the source unit’s Remote Turn-
On lead using a minimum of 1mm

2

wire.

NOTE: If your source unit does not have a
remote turn-on connection, connect the
amplifier’s (REM) terminal to the vehicle’s
accessory circuit.

Speaker Connections
Refer to the application guides on the
pages that follow. Speaker connections
should be made using a minimum of 
2.5mm

2

wire.

markedly, you will need to adjust the wire
gauge accordingly.
