Power / Ground
cable size

It is critical to use the proper 
power and ground cable. Select 
the size listed here for your 
amplifi 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 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 
battery, the REM to the source unit 
turn-on wire and the GND to the 
chassis ground..

Bare metal

Connect the RCA cables to 
the INPUT connectors. The 
OUTPUT can be used to 
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 
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 fi ts your 
speaker confi guration.

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.

DO NOT USE AN EXISTING 
FACTORY BOLT!
