Power cable size
It is critical to use the proper power
and ground cable. Select the size
listed here for your amplifier model.
Always use high quality copper
cable. Visit our website for multi amp
system cable recommendations.
Properly route power,
speaker and RCA cables
through the vehicle.
Choose a mounting location
that will provide adequate air
ventilation. Mount the amplifier to
a secure surface. Do not mount
the amplifier upside down.
Attach the chassis ground, +12V and amp turn on
wire. It is important to make sure these connections
are very secure.
REM TURN ON / DC SENSE ON SWITCH
There are two methods of switching the amplifier on and off. Select the appropriate
position suited for your application.
REM TURN ON
This will turn on the amplifier when a +12v switched power typically
from a source unit, is connected to the Amp Turn On - BLUE wire on the main power
connection harness.
DC SENSE
The DC SENSE is for use with source units that do not offer RCA
outputs.
PLEASE NOTE:
If switch is set to DC sense on, the amplifier will not turn
on via the amplifiers remote turn on wire. So if amplifier will not turn on
please view this switch on the top control panel and adjust accordingly.

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 fits your speaker
configuration.
The chassis ground connection
is critical to the performance
of the amplifier. Choose a
location that is close to the
amplifier. Completely scrape
