Quick Start Guide

Place terminal in a secure
position so that it won’t
accidentally contact the
negative battery post
For power cable runs over 20 feet,
8ga is recommended.
Power cable size
and fusing
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. Visit our website for multi amp
system cable recommendations.
Be sure to use the proper fuse size
for each model. Some models require
an external fuse.
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.
Attach the chassis ground, +12V and remote wire.
It is important to make sure these connections are
very secure.
Bare metal
Connect the RCA cables to
the INPUT connectors. The
OUTPUT can be used to
provide input for a second
amplier.
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.
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!
