Amplifier Wiring

Power Connections

PA D4000.4 Fuse Size: 2 x 40 AMP ATC

Power connections accept up to 4 AWG wire.

4 AWG power and ground wire recommended for optimal performance.

Connect +12V to the battery through fuse holder. This connection provides +12V main power to the amplifier.

Power wire must be fused within 12" of the battery.

Ground the amplifier using a good chassis ground as close as possible to the amplifier.

Connect REM terminal to remote turn-on lead from the head unit. This connection provides +12V power to turn-on the amplifier.

Add extra ground wire between the negative terminal of the battery and the chassis.

Amplifier Installation

Mounting Locations

The location of your amplifier will depend on several important issues.. Due to the low profile and compact

size of the Polk Audio PA D Series amplifier, 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. When mounting your amplifier under a seat or similar area, keep a minimum of 1" of clearance around the amplifier for adequate cooling..

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..

INSTALLATION GUIDELINES

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 D Series amplifiers do 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 placed on top of the amplifier impede air flow and may cause damage..

1.

Please read this owner’s manual carefully before installing your amplifier..

2.

Disconnect the battery ground terminal prior to making any electrical connections..

3.

Check for any hazards or obstructions such as gas tanks, fuel or brake lines, and wiring harnesses

 

before mounting the amplifier..

4.

Pick a mounting location that will provide adequate access and ventilation and protect the amplifier

2Ω min

Bridging

The amplifier is capable of bridging two full range channels into a single full range channel with higher output power.. For instance, one Front and one Rear channel when wired as shown will increase the output power from 125W per channel to 400W per channel (for a 4 Ohm load).. The most common are shown in the figure: four full range channels, two full range channels and a bridged sub, or two bridged subwoofers..

Internal Bridging

Terminals that can be used in bridging mode are identified by the black and outlined boxes next to each terminal.. The two black boxes and the two outlined boxes work together to create an internally bridged hookup..

from heat, moisture, and dirt..

5.

Avoid sharp metal areas when routing cables to the amplifier, and run RCA cables away

 

from the power cables and other potentially noisy car harnesses..

6.

The amplifier should be grounded with a short, heavy gauge wire connected directly to the car

 

at a bare metal surface, preferably scraped body metal.. Do not use factory ground locations,

 

seat bolts, or brackets that are spot welded..

7.

Always fuse your power connection within 12 inches of the battery terminal.. Use a fuse or circuit breaker

 

rated slightly more than the on-board fuse(s) of the amplifier(s).. The gauge of power wire used should take

 

into account the total current draw of the system, and the length of wire used.. IASCA and other auto sound

 

competition organizations have charts available for this; you can also find a chart in the MECP study guide..

 

Minimum wire gauge recommendations for the individual amplifiers are listed on the specification page..

 

Always use the same gauge wire for the amplifier ground that you use for the power wire.. Be sure

 

to examine the battery ground cable of the vehicle, and if necessary, upgrade it by adding an additional

 

ground wire that is the same gauge as the amplifier’s power wire.. Remember, the amplifier can only

 

deliver its rated output when it is not current limited by the power and ground supply wires..

8.

This amplifier is designed to drive a speaker load that measures from 2 to 8 Ohms for full range channels

 

and 4 Ohm minimum for bridged channels.. Keep in mind that heat is the long-term enemy of automotive

 

electronics and the lower your speaker load, the more heat is generated.. For low-impedance speaker

4Ω min/bridged

applications or restricted ventilation installations, an external cooling fan may be advisable..
