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)
