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
cable to the amplier
negative terminal. It is
important to make sure this
connection is very tight.
Bare metal
Attach the main power cable
to the amplier +12V. The
cable must run directly to
the battery and be properly
fused and be very tight.
Attach the remote turn on
wire to the amplier remote
output of the source unit.
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!

Common System Setup

Input Mode

Input MODE switch combines right/left signals in MONO for improved bass performance with subwoofers.

Xover Mode

XOVER Mode switch sets the type of crossover that will be active for each set of channels.

High Pass Filter Adjustment

HPF control limits output below selected frequency to protect speakers and allow smooth transition.

Low Pass Filter Adjustment

LPF control limits output above selected frequency for a smooth transition to higher frequency speakers.
