It is critical to use the proper
power and ground cable. Select
the size listed here for your
amplier 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 amplier to
a secure surface. Do not mount
the amplier 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
amplier.
The HI INPUT is for use with
source units that do not offer
RCA outputs. Use the supplied
harness to connect to the
source unit’s speaker output.
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.
Using spade terminals,connect
the speaker cables to the speaker
output connectors. Follow the
diagram below that best ts your
speaker conguration.
The chassis ground connection
is critical to the performance
of the amplier. Choose a
location that is close to the
amplier. Completely scrape
away the paint and use a nut
and bolt if possible.
DO NOT USE AN EXISTING
FACTORY BOLT!
