Positive
Battery
Terminal
Fuse must be
installed within
18" of battery
Drill a hole in the
firewall and use
a rubber grommet
to keep wire
from shortings
Run the cables under
the carpet near the
side of the vehicle.
Be careful not to drill
or screw into the
wires when you
replace the trim.
Ground wire to solid
metal of rear chassis
Avoid sharp edges that
could chafe through the
insulation
Run signal cables
(RCAs) and
remote turn-on
lead
down the
opposite side of
the vehicle of the
power
wire to avoid
radiated noise
Factory Ground wire may
need to be replaced if it is
small, frayed, or broken
Before beginning, disconnect the negative (-) terminal of the battery prior to
working on the positive (+) terminal to prevent a short to ground. This is impor-
tant to avoid serious damage to your car audio system and your car electrics.
Reconnect the negative terminal only after all connections have been made.

KEY TO CALLOUTS
GND - Main ground connection. Bolt to a clean chassis point in the vehicle.
+12V - Connected to a fuse or circuit breaker, then to the battery’s positive terminal.
REM - Remote Turn-ON is connected to Radio's power antenna lead or a switchable
+12V - FUSES- Satellite channels power supply fuses.
Warning: Replace only with the same value fuses
Speaker Connection Terminal - Connect Speakers here - ensure correct polarity.
Subsonic Filter - Frequency adjustment control for Subsonic Filter.
Selectable X-Over LP/HP/FULL
LP - Frequency adjustment control for Low Pass Filter
HP - Frequency adjustment control for High Pass Filter
Full - Full Range Signal Output
Hawkins Bass-EQ Control Adjustment
Frequency adjustment control for Hawkins Bass Control filter.
Hawkins Bass-Boost Control Adjustment
Varies from 0 to + 18 dB of boost when the Hawkins Bass Control circuit is engaged.
Input Attention: ATT. Switch ‘ON’ for high voltage input (4V to 12V) capability. This
switch ‘ON’ must be used for speaker level input on common ground headunits
or high voltage line drivers.
Input Gain - Input gain control variable from 150mV to 4V or 4V to 12V
RCA Inputs - Connect the RCA cables from source unit, or line driver to these
RCA connectors.
RCA Line Outputs - Left and right RCA Line outputs provides Full Range Signal.
Status LED - Indicates amplifier power. (Power: Green / Protection : Red)
