1. Speaker Connections—accepts up to 12 AWG speaker wire.
2. 2 ATC Fuses—protects the amplifier from over current situations.
3. Power Connections—accepts up to 4 AWG power cables.
4. REM Remote Turn-on Input—turns on/off the amplifier when fed Switched 9-15 V+.
5. Ground Connection—accepts up to 4 AWG ground cable.
SPEAKER LEVEL HARNESSES
Do not connect the high level input connections to power, signal, or chassis ground as damage to the head-unit
outputs may result. The high-level inputs are designed to work with either grounded or BTL speaker level outputs

Signal Input and Output Configurations
The input section of the amplifier consists of a phase switch that sets the output configuration, gain controls,
and line level inputs. The input section makes it easy to adapt this amplifier to most system configurations.
Phase Switches ­*
nnд®
К UК 0°—leaves output unaffected. The output signal is in phase with the input signal.
Ê UÊ 180°—inverts the output. The channel is 180° out of phase. This configuration is useful for inverting the phase
of subwoofers to improve staging in a vehicle. This is also used when bridging two amplifiers into one speaker.
Auxiliary Output Configurations ­*
nnä®
The auxiliary outputs on Polk Audio PA amplifiers offer easy, unlimited system expansion. Routing signal from
a source unit, pre-amplifier, or equalizer is a matter of connecting cables to the line level inputs and the line
level outputs to your next Polk Audio PA amplifier in the signal chain. The signal passes through a buffer
stage so that several amplifiers can be daisy chained without signal loss or overloading of the source unit.
This maximizes the signal output and minimizes the potential for system noise.

is continuously variable from 50Hz to 500Hz.
Remote Bass Operation ­*
nnä®
The remote bass port provides easy remote access to the internal bass gain structure of the power amplifier.
The bass gain is centered at 44Hz. The PRGC-1 plugs into the amplifier via the 1/8" mini jack plug. The PRGC-1
can be installed in the front of the vehicle to control the amplifier bass gain level. The PRGC-1 can be used
as a bass level control when used on an amplifier dedicated to subwoofers.
