quality copper cable.
Cable size recommendations for
multi amp systems are available

Properly route power,
speaker and RCA cables
through the vehicle.
Choose a mounting location
that will provide adequate air
ventilation. Mount the amplifi er to
a secure surface. Do not mount
the amplifi er upside down.
Using spade terminals, connect the
+12V to the power cable from the

Connect the RCA cables to
the INPUT connectors. The

provide input for a second
amplifi 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

The chassis ground connection
is critical to the performance
of the amplifi er. Choose a
location that is close to the
amplifi er. Completely scrape
away the paint and use a nut
and bolt if possible.
