9.Battery and ground connections to the vehicle should be made with crimped ring terminals of the appropriate size (surface area is what counts;) soldering the terminals after crimping is also recommended..

10.Due to the high-frequency MOSFET switching power supply, filtering the power cable is not generally required (remember that the amp can’t deliver full output if the power supply is restricted..) Proper grounding of the signal source is mandatory for the amplifier to reach its performance peak.. If the RCA inputs are not grounded adequately via the signal source, electrical noise from the vehicle may be picked up in the system..

Step By Step Installation

1.Determine the location for the amplifier.. Refer to the Mounting Locations section of this guide..

2.Decide on the system configuration for your amplifier.. For system suggestions, refer to the Speaker Wiring Diagrams section of this guide..

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..

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.

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..

6.Turn the vehicle’s key switch to the off position..

7.Disconnect the vehicle’s battery ground terminal..

8.Connect power wires to the amplifier (ground first, then +12V and REM).

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 D Series amplifier.. Refer to the Line Level Inputs/Controls and Speaker Wiring Diagrams sections of this guide for correct wiring instructions..

10.Reconnect the ground terminal to the battery after power, speaker, and line level connections are completed..

11.Set crossovers.. Refer to the Line Level Inputs/Controls section of this manual for detailed instructions..

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 D Series amplifier..

1.Check all the wiring connections to be sure they are correct and secure..

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..

3.Turn the level controls of the amplifier to their minimum positions..

4.Turn the head 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 Inputs/Speaker Outputs and the Troubleshooting Tips sections of this manual for instructions..

5.If using an aftermarket head unit, turn the level controls of the amplifier about one quarter of a turn counterclockwise.. Slowly increase the volume level of the head 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 Inputs/Speaker Outputs and the Troubleshooting Tips sections of this manual to solve your installation problems..

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 Line Level Inputs/Controls section of this manual and take corrective action..

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 (see Line Level Inputs/Controls on page 4)..

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..

2.Turn the level controls of the amplifier to their minimum positions..

3.Choose music with high dynamic content that you like, with which you are familiar, and will be used most often in the system..

4.Turn the head 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 head unit.. Listen for any audible distortion.. If any distortion is audible, reduce the volume of the head unit until you have an undistorted output.. Leave the volume control at this position during your system tuning..

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..

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..

7.Fine-tune the output level between midrange and tweeters.. Refer to the Line Level Inputs/Controls section of this manual for detailed instructions..

8.Repeat Steps 5-7 for the rear speakers.. If you do not have rear speakers continue to Step 10..

9.Set levels between the front and rear midrange and tweeters for optimum front/rear balance..

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..

11.Fine-tune the output level between satellite speakers and the woofers.. Refer to the Line Level Inputs/Controls section of this manual for controls.. Adjust the level to the bass output of the woofer to match the sonic requirements of the system..

12.Enjoy your awesome Polk Audio PA D Series amplifier..
