Important Safety Considerations

• To prevent personal injury and damage to the unit, please read

the following instructions in this manual.

• This product is designed to use in vehicles with 12Volt,

negative-ground electrical systems.

• Install this product in a dry location away from your vehicles’

safety equipment (airbags, seat belt system, etc.). Water and

humidity may damage internal components.

• Use the included mounting accessories to secure this product

so that it does not come loose.

• Check before drilling to make sure you do not drill into any vital

vehicle system.

• Protect all system wiring from sharp metal edges.

• Do not disassemble or modify this unit; doing so will void your

manufacturer’s warranty.

Important Installation Precautions

Installation of mobile audio equipment requires experience.

Although this manual provides general installation procedures,

it will not show the exact installation method for your particular

vehicle.

If you do not have the required knowledge and experience,

we recommend that you have your equipment installed by an

Authorized Aunex Dealer.

• Turn o all stereo and other electrical devices before you begin.

• Disconnect the negative (-) lead from your vehicle’s battery to

avoid an electrical short.

• Check the mounting depth to make sure there is sucient room

for your installation placement preference.

• When running power cables through sheet metal it is best to use

grommets and loom to properly insulate the metal edges.

Mounting Placement

The AP-4EQ was designed to be installed in or near the

dashboard of most vehicles. The front panel was designed

so that the equalizer would be mounted ush to your vehicles’

dash. There are dash kits from many brands that allows for the

equalizer to be mounted alongside your headunit. Check with your

Authorized Aunex Dealer for additional information and options.

Other popular mounting options are under the dashboard or in

your glove compartment. For these methods, you will use the

supplied mounting brackets as shown below. Make sure there

are no items behind the area where the screws will be driven.

For optimum sound quality, it is highly recommended that you

purchase Aunex wiring accessories as they are designed to give

your equalizer and ampliers the high-quality signal it needs to

operate at peak performance levels. Aunex has everything from

RCA cables and power wire to speaker wire and battery connectors.

1. Main Volume: This knob controls the volume level of your Front

and Rear outputs. It is recommended that you set your radio

volume at the desired listening level and make your sound

adjustments from your equalizer.

2. Fader: This knob will allow you to fade the signal level between

your Front and Rear outputs. This will allow you to have Front

and Rear fading capabilities with only one pair of inputs.

3. Dual Input Selector: This button allows you to select the input

signal from either your main Head Unit or Aux Input.

4. Input Voltage Selector: On the top of the AP-4EQ is a switch

to select either Low Level RCA Input (left side position) or High

Level Speaker Input (right side position). The High-Level input

allows you to connect speaker outputs from our factory radio to

the equalizer without the need of a high to low level converter.

5. Subwoofer Frequency: This knob allows you to select the

center frequency range of your subwoofer output from 40Hz to

150Hz.

6. Subwoofer Volume: This knob controls the volume level of your

Subwoofer Output and is independent from the Main Volume

knob.

7. Equalizer Knobs: These 4 knobs allows you to control the Bass

(75Hz), Mid-Bass (500Hz), Midrange (2.5kHz) and High (10kHz)

frequencies with a 18dB of defeat or boost.

8. Auxiliary Input: This 3.5mm input jack allows you to connect

your phone or portable audio player directly to your equalizer. Be

sure to select Aux input mode when in use from the front

panel button.

1. Power Connector: This connector has inputs for Ground,

Remote and Power.

a. Ground: Use the same gauge wire that is being used for the

Power connection and run your ground wire to this negative

terminal. Good ground points are from your battery, a ground

buss or a veried ground location that is clean. This will

minimize the possibility of noise induced into the system.

(Factory head unit ground is not recommended as it can induce

unwanted noise.)

b. Remote: Use a 22 to 18 Gauge wire from your head unit’s

remote turn-on (+12VDC Switched) and run it to remote terminal.

c. Power: Use the supplied in-line fuse and connect it to a

constant positive +12 volt source. Use the same gauge wire

that is used for the ground; preferably 18 Gauge or larger and run

it to the +12 Volt terminal.

2. High Level Input: If you are going to use High Level Input

instead of the Low Level RCA’s inputs, you will need to be set

the gains on your ampliers lower as the output voltage of the

AP-4EQ is stronger with High Level Input than Low Level RCA

Inputs.

Low Level RCA Connections: Aunex recommends using high

quality RCA Interconnects such as the Aunex AP RCA and AE

RCA series. Consult with your Authorized Aunex Dealer to see

what cable and length works best for your installation. (Note:

Avoid crossing your power and wire ground with your RCA

cables. This will help prevent noise interference.)

3. Main: Use this pair of inputs to connect your main source /

headunit.

Rear Panel Controls

4. Rear: Use this pair of outputs to connect to your rear amplier

or rear channels of your amplier.

5. Front: Use this pair of outputs to connect to your front amplier

or front channels of your amplier.

6. Subwoofer: Use this pair of outputs to connect to your

subwoofer amplier or subwoofer channels of your amplier.

The above example illustrates the most common use of

the AP-4EQ utilizing 3 ampliers and a headunit. The signal

connections from the headunit can be from either the

High-Level Input or the Low-Level RCA Inputs. Depending

on which input method you use, be sure to position the top

switch to the appropriate mode. It is recommended to not

connect the High-Level and Low-Level Input simultaneously.

Tuning the 4 Bands of equalization is set by your listening

preference as dierent music genre are produced with

dierent quality and dierent equalizations. The AP-4EQ was

designed to help you compensate these recording dierences by

allowing you to ne tune your system for your listening enjoyment.

The 4 Bands of equalization does not aect your

subwoofer channel as your subwoofer channel already has its

own independent frequency range and volume knob. Instead the

equalization bands will only aect the Front and Rear Outputs.

- Bass (75Hz Centered): Use this knob sparingly as most

coaxials speakers and components cannot handle 18dB of

boost. However, in some music you will nd that turning up this

knob will enhance the low frequency output.

- Mid-Bass (500Hz Centered): Use this knob to control

frequencies that are above subwoofer bass and below midrange

which is also called low order harmonics. This range is normally

associated with Male vocals, brass instruments.

- Mid-Range (2.5kHz Centered): Use this knob to control

frequencies that are associated with musical instruments and

female vocals. Over boosting this region can harm your hearing

as your ears are particularly sensitive to how voice sounds and

it’s frequency coverage.

- High (10kHz Centered): Use this knob to control the upper

frequency spectrum which is also known as the brilliance range.

Boosting this range can make a recording sound more Hi-Fi.

However over boosting this range can also cause excessive

hiss and listening fatigue.
