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. Reconnect the negative lead to your

battery once your installation is complete. So, in other words

the negative lead from our vehicle’s battery is the rst

connection you remove before starting your installation and

the last connect your make after you nish your installation.

• Check your mounting location to make sure there is sucient

room for your installation placement preference.

Mounting Placement

Choose a structurally sound location to mount your Aunex

amplier, making 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 ampliers high-quality signal it needs to operate at peak

performance levels. Aunex provides a wide selection from

RCA cables and power wire to speaker wire and battery

connectors.

Important Installation Precautions Continued

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

safety equipment. Each AC Series amplier circuit board has

been coated with a protective layer of Conformal Coating. This

will help protect the electronic circuit from harsh environments

that may contain humidity and a range of airborne contaminants

and varying temperatures. However prolonged exposure to

water and high humidity may damage internal components in

time. Keeping the amplier dry and installed in a well-ventilated

area will help ensure many years of listening enjoyment.

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

use grommets and loom to properly insulate your cables from

metal edges.

• Avoid mounting the amplier with the top ns facing down as

this may increase the operating temperature of your amplier.

• If mounting underneath a seat, make sure that there is at least

1 inch (25mm) of space above the amplier to permit proper

cooling.

• Avoid mounting the ampliers on a subwoofer enclosure as

prolonged excessive vibration may damage your amplier.

1. Remote Level Control: With the Remote Level Control plugged

to your amplier, you can now adjust the amount of output from

the convenience of this controller. There are several mounting

options for your controller. With the supplied wing attachment,

you can mount the controller under your dash. Should you want

to mount the controller ush to your dash, arm rest or any other

panel of your vehicle the wing attachment will more than likely

not be needed.

2. Clipping Led Indicators: These LED’s will light up when the

amplier output signal is being clipped. When the LED’s starts

to glow, your amplier output is between 1-2% THD (Total

Harmonic Distortion). When the clipping indicators are fully lit,

your amplier output is between 6-7% THD (Total Harmonic

Distortion). The ideal gain setting is where the clip indicators

are not lit allowing the amplier to send undistorted clean

output. Setting the ampliers gains improperly where the clip

indicators are always lit will over-work the amplier and may

cause excessive heat building and possibly product failure.

3. Boost Eq: Your AC Series ampliers incorporates a Boost Eq.

circuit that can increase output 0-18dB centered at 45Hz. Note if

you turn up the Boost Eq, you will need to readjust the Input

Gains to avoid clipping the output signal. Using the Clipping

LED’s will help set your Boost Eq and Input Gains properly.

4. Infrasonic Filter: This variable potentiometer will provide a roll

o point for lower frequencies (10Hz – 50Hz variable) that could

potentially damage your subwoofers from over-excursion. The

frequency setting for your Infrasonic Filter is to be set relative

to your subwoofers low-frequency capabilities along with

enclosure tuning. In a sealed box Aunex recommends setting

the Infrasonic Filter between 25Hz – 35Hz. In a ported enclosure

Aunex recommends setting the Infrasonic lter at ½ an Octave

below your tuned frequency.

For example, let say your ported enclosure is tuned at 40Hz.

Take ½ of 40Hz which is 20Hz (this is one octave lower). Now

take another half o 20Hz which is then 10Hz (this is half an

octave lower). Now take 10Hz from 40Hz which is 30Hz and

where you should set your Infrasonic Filter.

5. Low Pass (LP) Filter Frequency Filter: This potentiometer

allow you to adjust the crossover frequency from 50Hz – 250Hz.

6. Phase Switch: Depending on the absolute phase of your main

speakers and amplier and the distances of the subwoofers

and the main speakers from the main listening position, the

bass in the crossover region maybe smoother if you reverse the

subwoofer’s phase. Try both settings to determine which

polarity produces the best overall bass performance in your

system. Typically though, phase is left at the 0⁰ for most

installation.

7. Input Gain: Use this Input Gain Potentiometer to match the

output voltage of your headunit / source unit to the input circuit

of your amplier. This Input Gain is not a volume knob. A

simple method of setting your Input Gain is to turn your headunit

/ source unit up to approximately ¾ volume. Then slowly adjust

your Input Gain on your ampliers clockwise until you can hear

distortion from your subwoofer(s). Then turn the gains down

(counterclockwise) till the distortion is no longer heard and your

clipping indicators are not lit.

8. Low Level RCA Inputs: These are your dierential

balanced inputs that are used to connect audio signal from

your headunit / source unit to your amplier. Your AC Series

Amplier is capable to receiving either High Level

Speaker Outputs or Low-Level RCA cables. If you are

using High Level Speaker outputs, you may need a high

to low level adapter such as the Aunex AP-SL2 adapter.

9. Speaker Outputs: Your AC amplier speaker outputs are

designed to accept 16 AWG to 8 AWG wire. Turn the set

screws on this terminal counterclockwise to loosen the

screws using the supplied Hex wrench. Strip the PVC jacket

from your speaker wire ½ inch (12mm). Then insert the bare

wire into the terminal block so that no bare speaker wire is

exposed. Then tighten the set screw by turning it clockwise.

Loading your amplier below the recommended

impedance rating found on page 13 is not

recommended and may cause your amplier to

enter into protection mode and may void your warranty.

For maximum current ow, Aunex recommends that you tin

your speaker wire before connecting it to the speaker output

terminals. In addition, Aunex recommends using high

quality 100% OFC (Oxygen Free Cooper) or Tinned 100% OFC

speaker wire. This will ensure that your speaker /

subwoofer receives maximum output from your amplier.

10. Fuse Holder: This is your fuse block. The AC500.1D

and the AC1000.1D has fuses mounted on the side

panel. The AC1500.1D includes an external fuse holder.

Should there be a short in your system or if your amplier is

being overdriven, these fuse(s) will typically burn to prevent

damage to your amplier. If it is required to replace your

fuse(s), use the same fuse rating that comes with your

amplier. Using a higher fuse may damage your amplier

and will void your warranty.

Side Panel Layout Continued

11. +12Volt Positive Terminal: The +12Volt positive terminal is

designed to accept up to 4 AWG wire. Use the supplied fuse

block and make your +12Volt connection directly to the positive

battery post. The Fuse should be installed within 18” (457mm)

of the battery. This fuse is vital to protecting the vehicle and

amplier from a dead short. Turn the set screws on this terminal

counterclockwise to loosen the screw using the supplied Hex

wrench. Strip the PVC jacket from your speaker wire ½ inch

(12mm). Then insert the bare wire into the terminal block so that

no bare power wire is exposed. Then tighten the set screw by

turning it clockwise.

For maximum current ow, Aunex recommends that you tin

your power wire before connecting it to the +12Volt terminal. In

addition, Aunex recommends using high quality 100% OFC

(Oxygen Free Cooper) or Tinned 100% OFC speaker wire. This

will ensure that your speaker / subwoofer receives maximum

output from your amplier.

12. Remote Input Terminal: This terminal must be connected to

a switched +12Volt source. If the source unit does not have a

remote Turn on lead, then a switched +12 supply should be

used such as the ACC +12Volt. Run an 18-gauge wire from the

Remote Turn-On Lead from your headunit / source unit to this

terminal.

If you are using the High-Level Speaker Outputs connection

to the ampliers’ RCA inputs, you do not need to connect

a remote input to your amplier. Your amplier will

automatically detect the speaker signal and will turn on

your amplier via its DC Oset circuit. In addition, the

remote input terminal then becomes a remote output

trigger which can be used to turn on another amplier

or processor that requires a +12volt remote connection.
