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 sucient
room for your installation placement preference.

Mounting Placement
Choose a structurally sound location to mount your Aunex
amplier, 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 ampliers 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 amplier 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 amplier 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 amplier with the top ns facing down as
this may increase the operating temperature of your amplier.
• If mounting underneath a seat, make sure that there is at least
1 inch (25mm) of space above the amplier to permit proper
cooling.
• Avoid mounting the ampliers on a subwoofer enclosure as
prolonged excessive vibration may damage your amplier.

1. Low Level RCA Inputs: These are your dierential balanced
inputs that are used to connect audio signal from your headunit /
source unit to your amplier. Your AC Series Amplier 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.
2. Input Mode Selector: This switch allows you to select the
number of RCA inputs used to send audio signal to your
amplier. In 2 Channel Mode, only 1 set of RCA inputs is
needed to drive all 4 output channels. (You will need to set the
Input Mode switch to the 2Ch. position.) In 4 Channel Mode, all
4 RCA inputs will be connected and the Input Mode switch will
need to be set to the 4Ch. position.
3. Clipping Led Indicators: These LED’s will light up when the
amplier output signal is being clipped. When the LED’s starts
to glow, your amplier output is between 1-2% THD (Total
Harmonic Distortion). When the clipping indicators are fully lit,
your amplier output is between 6-7% THD (Total Harmonic
Distortion). The ideal gain setting is where the clip indicators are
not lit allowing the amplier to send undistorted clean output.
Setting the ampliers gains improperly where the clip indicators
are always lit will over-work the amplier and may cause
excessive heat building and possibly product.
4. Input Gain: Use these Input Gain Potentiometers to match the
output voltage of your headunit / source unit to the input circuit
of your amplier. These Input Gains are not a volume knob.
A simple method of setting your Input Gains is to turn your
head adunit / source unit up to approximately ¾ volume. Then
slowly adjust your Input Gains on your ampliers clockwise until
you can hear distortion from your speakers or subwoofers. Then
turn the gains down (counter clockwise) till the distortion is no
longer heard and your clipping indicators are not lit.

5. Boost Eq: Your AC Series amplier incorporates a two stage
Boost Eq. circuit that is not only active in Low Pass Mode but is
also active in High Pass Mode. In Low Pass Mode, the Boost
Eq. can increase output 0-18dB centered at 45Hz. In High Pass
Mode, the Boost Eq can increase output 0-18dB centered
at 12kHz. 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.
6. Low Pass (LP/BP) Filter Frequency Filter: This
potentiometer is used when the amplier is set to Low Pass
Mode and allows you to adjust the crossover frequency from
40Hz – 400Hz.
7. Crossover Filter Selector: Depending on how you will use
your AC Amplier, you will select the appropriate setting on the
Crossover switch. Set the Crossover Switch to LP/BP mode if
you are using Subwoofers or MidBass drivers. Set the switch
to HP if you want the amplier’s internal crossover to serve as
a high pass lter. When the switch is set to the Full position
will allow the amplier to send its full bandwidth to your
speakers. Avoid changing the crossover switches with the
audio system playing at high volumes as this may damage
your speakers.
8. High Pass Filter Frequency Filter: This potentiometer is
used when the amplier is set to High Pass Mode and allows
you to adjust the crossover frequency from 40Hz – 400Hz.
9. Multiplier x1 and x10 Selector: This selector is a
frequency multiplier that aects the HP Filter. If the amplier is
used in High Pass mode, selecting the x1 position will allow you
to adjust the frequency between 40Hz – 400Hz and up. Pushing
the button to the x10 position will now allow you to adjust the
frequency between 400Hz to 4,000Hz and up. Using the x10
position is ideal if you are using the amplier to run midranges
where you do not want lower frequencies to be reproduced.

10. Speaker Outputs: Your AC amplier 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 amplier below the recommended
impedance rating found on page 15 is not
recommended and may cause your amplier 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 amplier.
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
amplier from a dead short. Turn the set screws on this termi-
nal 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 speaker 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 amplier.
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 ampliers’ RCA inputs, you do not need to connect
a remote input to your amplier. Your amplier will
automatically detect the speaker signal and will turn on
your amplier via its DC Oset circuit. In addition, the
remote input terminal then becomes a remote output
trigger which can be used to turn on another amplier
or processor that requires a +12volt remote connection.
13. Ground: The Ground terminal is designed to
accept up to 4 AWG wire. Make your ground connection
directly to the chassis of the vehicle as close to the amplier as
possible. Make sure this connection is made with the
same gauge wire as used for your +12Volt connection.
Ensure that all dirt, grease and paint is removed from your
chassis ground point prior to attaching the ground wire. Aunex
recommends when making your chassis ground to use a
Star Washer which will help prevent your ground bolt from
loosening.
