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 * nnä®
ÊUÊ 0°—leaves output unaffected. The output signal is in phase with the input signal.
ÊUÊ 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.

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.

AMPLIFIER INSTALLATION
Choosing Mounting Locations
The location of your amplifier will depend on several important issues. Due to the low profile size of the
PA amplifiers, there are many possible installation locations that will yield satisfactory amplifier performance. Always mount the amplifier in a place that protects the amplifier from the elements. In addition, mount the amplifier on a stable, flat surface.
NOTE: Mounting amplifiers upside down is not recommended and may cause premature thermal shutdown.
WARNING! Do not mount any amplifier in the engine compartment. Amplifiers are not designed to endure the harsh environment of an engine compartment.
Passenger Compartment
If you are going to mount the amplifier in the passenger compartment, make sure you have adequate room
for ventilation. The amplifiers have been designed to make under-seat mounting possible. When mounting your amplifier under a seat or similar area, keep a minimum of 1" of clearance around the amplifier for adequate cooling.
Trunk Compartment
Mounting your amplifier in the trunk provides excellent performance as long as you do not restrict the airflow around the heatsink of the amplifier. For optimal results, mount the amplifier with as much clearance as possible. This type of mounting will yield the best cooling due to the convection effect of the amplifier chassis.
General Precautions and Installation Tips
WARNING! Be careful not to cut or drill into gas tanks, fuel lines, brake lines, hydraulic lines, vacuum lines, or electrical wiring when working on your vehicle.
Disconnect the vehicle’s ground wire at the battery before making or breaking connections to the audio system’s power supply terminals.
Do not use this amplifier unmounted. Failing to securely mount the amplifier can result in damage or injury, particularly in the event of an accident. An unmounted amplifier becomes a dangerous projectile in the event of a crash. Never mount the amplifier where it might get wet. Mount the amplifier so the wire connections will not be pulled. Route the wires where they will not be scraped, pinched or damaged in any fashion.
The +12V power supply wire must be fused as close as possible to the battery terminal, ideally within 18".
1ÃiÊÌ iÊÀiV i `i`ÊvÕÃiÊÃ âiÊ ÀÊV ÀVÕ ÌÊLÀi> iÀÊ ÃÌi`Ê ÊÌ iÊPower Connections section of this manual.
If you need to replace the fuse plugged into the side of the amplifier, replace the fuse with the same size ATC/MAXI type fuse that came with the amplifier. If you are not sure as to the correct value, refer to the
Power ConnectionsÊÃiVÌ Ê vÊÌ ÃÊ > Õ> Êv ÀÊ`iÌ> ðÊÊ1à }Ê>Ê } iÀÊVÕÀÀi ÌÊvÕÃiÊ >ÞÊÀiÃÕ ÌÊ Ê`> >}iÊ to the amplifier that is not covered under warranty.
NOTE: Make sure all the equipment in the system is turned off when making or breaking connections
to the input Line levels or speaker terminals. Turn on the system and slowly turn up the volume control only after double checking all wire connections.
Power for systems with a single amplifier can be supplied by most automotive electrical systems. Systems with multiple amplifiers may require a higher capacity battery, alternator or the use of a storage capacitor.
Polk Audio PA amplifiers generate a certain amount of heat as part of normal operation. Be sure the area around
the amplifier is unobstructed to allow adequate air circulation. Remember, beach blankets, last week’s laundry, school books and homework papers located on top of the amplifier do not improve air flow and may become damaged.

Step By Step Installation
Step 1: Determine the location for the amplifier. Refer to the Choosing Mounting Locations section of this guide for detailed information.
Step 2: Decide on the system configuration for your amplifier. For system suggestions, refer to the Speaker Wiring Diagrams section of this guide.
Step 3: Run all the wires from the amplifier location to the speakers, source unit, and battery. Do not connect
the battery at this time. Be sure to run Line levels and power and speaker wires away from factory electrical wires and system as they pose a great potential for induced system noise.
Step 4: Pre-drill amplifier mounting holes. Be sure to “think before you drill.“ Gas tanks, fuel lines, and other obstructions have a nasty way of hiding themselves. For best results use a marking pen to mark
the mounting holes and pre-drill these holes with a standard 1/8" drill bit.
Step 5: Mount the amplifier. Make sure the amplifier is mounted on a flat surface. If this is not possible, do not over tighten the screws so that the chassis of the amplifier is twisted or bent.
Step 6: Turn the vehicle’s key switch to the off position. Step 7: Disconnect the vehicle’s battery ground terminal.
Step 8:Ê iVÌÊ« ÜiÀÊÜ ÀiÃÊÌ ÊÌ iÊ> « v iÀÊ}À Õ `Êv ÀÃÌ]ÊÌ i Ê£ÓÊ6³®Ê> `Ê, ®°
Step 9: Connect the line level and speaker wires to the amplifier. Check the quality of your speakers and signal connections. This will determine the ultimate performance of your Polk Audio PA amplifier. Refer to the Amplifier Settings and Speaker Wiring Diagrams sections of this guide for correct wiring instructions.
Step 10: Reconnect the ground terminal to the battery after power, speaker, and line level connections are completed. Step 11: Set crossovers. Refer to the Amplifier Settings section of this manual for detailed instructions.
Step 12: Once satisfied that all connections and settings are correct, install the fuse located near the vehicle’s battery and proceed to the Testing the System section of this manual.
WARNING! Never exceed the recommended fuse size of this amplifier. Failure to do so will result in the voiding of your warranty and possible damage to the amplifier.
SET UP AND TROUBLESHOOTING
Testing the System
After you have completed the installation, you need to test the system. This will help ensure years of trouble-free operation. Please refer to the listed steps below when testing the sound of your Polk Audio PA system.
Step 1: Check all the wiring connections to be sure they are correct and secure.
Step 2: Turn the signal source volume control all the way down. Set any tone controls to their flat or defeated positions. This includes the loudness control.
Step 3: Turn the level controls of the amplifier to their minimum positions.
Step 4: Turn the source unit on. Check to see if the power LED located on the connection side of the amplifier is on. If not, please refer to the Power Connections and the Troubleshooting Tips sections of this manual for instructions.
Step 5: If using an aftermarket source unit, turn the level controls of the amplifier about one quarter of a turn counterclockwise.
Slowly increase the volume level of the source unit so that you can hear the output of the system.
If no sound is heard or if the output is distorted, turn the system off immediately. Refer to the Power Connections and the Troubleshooting Tips sections of this manual to solve your installation problems.
Step 6: Check to make sure the output for each channel is correct. If the active crossovers are used, check to make sure that each output is correct from the amplifier. When using active crossovers on midrange and tweeters, do not use crossover frequencies lower than recommended. If the system is not configured properly, refer
to the Amplifier Settings section of this manual and take corrective action.
Step 7: If the output is clear and undistorted, continue to the Adjusting the Sound of the System section of this manual.
Adjusting the Sound of the System
Once you have checked the system’s operation, adjust the sound of the system. Adjusting the sound of the system is accomplished by setting the level controls and adjusting the internal crossovers.
Step 1: Turn the signal source volume control all the way down. Set any tone controls to their flat or defeated positions. This includes the loudness control.
Step 2: Turn the level controls of the amplifier to their minimum positions.
Step 3: Choose music with high dynamic content that you like, with which you are familiar, and will be used most often in the system.
Step 4: Turn the source unit’s volume control up to its highest undistorted output level. If you lack test equipment, this point occurs between 3/4 to full volume depending on the quality of your source unit. Listen for any audible distortion. If any distortion is audible, reduce the volume of the source unit until you have an undistorted output. Leave the volume control at this position during your system tuning.
Step 5: While listening to your chosen dynamic music, turn up the level control corresponding
to the midrange output until you hear slight distortion and turn the level control back slightly for an undistorted output. Depending on your system, the midrange and tweeter output may be on the same output channels.
Step 6: Turn up the level control corresponding to the tweeter output until you hear slight distortion and turn back the level control slightly for an undistorted output. Depending on your system the midrange and tweeter output may be on the same output channels.
Step 7: Fine-tune the output level between midrange and tweeters. Refer to the Amplifier Settings section of this manual for detailed instructions.
Step 8: Repeat Steps 5-7 for the rear speakers. If you do not have rear speakers continue to Step 10. Step 9: Set levels between the front and rear midrange and tweeters for optimum front/rear balance.
Step 10: Turn up the level control corresponding to the woofer output until you hear slight distortion and turn back the level control slightly for an undistorted output.
Step 11: Fine-tune the output level between satellite speakers and the woofers. Refer to the Amplifier Settings section of this manual for detailed instructions. If using an PRGC-1, adjust the level to the bass output of the woofer to match the sonic requirements of the system.
Step 12: Enjoy your awesome Polk Audio PA sound system.
