cable size
It is critical to use the proper
power and ground cable. Select
the size listed here for your
amplier model. Always use high
quality copper cable.
Cable size recommendations for
multi amp systems are available
on our website.
Properly route power,
speaker and RCA cables
through the vehicle.
Choose a mounting location
that will provide adequate air
ventilation. Mount the amplier to
a secure surface. Do not mount
the amplier upside down.
Using spade terminals, connect the
+12V to the power cable from the
battery, the REM to the source unit
turn-on wire and the GND to the
chassis ground..

Connect the RCA cables to
the INPUT connectors. The
OUTPUT can be used to
provide input for a second
amplier.
Connect the power cable to the
positive battery terminal. The
power cable must be fused
within 18 inches of the battery
terminal.
Re-connect the negative
battery terminal making sure it
is securely tightened.
The chassis ground connection is
critical to the performance of the
amplier. Choose a location that is
close to the amplier. Completely
scrape away the paint and use a nut
and bolt if possible.
DO NOT USE AN EXISTING
FACTORY BOLT!
