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. 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. Frequency Filter: This potentiometer is used to adjust the
crossover frequency of your amplier. When the Crossover
lter is switched to Low Pass the crossover frequency
adjustment is 30Hz – 500Hz. When the amplier lter is
switched to High Pass, the crossover frequency adjustment is
50Hz – 500Hz.
2. Crossover Filter Selector: Depending on how you will use
your AP Amplier, you will select the appropriate setting on the
Crossover switch. Set the Crossover Switch to LP 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.
3. Boost Eq: Your AP Series ampliers incorporate a two stage
Boost Eq. circuit that is not only active in Low Pass Mode but
is also active in Full Range Mode. The Boost Eq. can increase
output 0-18dB centered at 45Hz.
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
headunit / 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 (counterclockwise) till the distortion is no
longer heard.
5. 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. (Note only one type of
input is needed to send signal to your amplier, therefore
you only need to use either your Low Level or High-Level
input. Aunex does not recommend connecting both Inputs
simultaneously.

6. High Level Input: These are your High-Level Speaker
Input that are used to connect your speaker outputs from your
headunit / source unit to your amplier. (Note only one type of
input is needed to send signal to your amplier, therefore
you only need to use either your Low Level or High-Level
input. Aunex does not recommend connecting both Inputs
simultaneously.)
7. Speaker Outputs: Your AP Amplier speaker outputs are
designed to accept 16 AWG to 12 AWG wire. 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 speaker wire is exposed. Then
tighten the set screw by turning it clockwise.
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.
Visit www.aunexusa.com or talk to your Authorized Aunex
Dealer to see a complete selection of premium installation
accessory that will complement and enhance listening
experience.
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.
8. Fuse Holder: This is your fuse block. Should there be a short in
your system or if your amplier is being overdriven, these fuse(s)
will typically burn to prevent damage to your amplier. If it is
required to replace your fuse(s), use the same fuse rating that
comes with your amplier. Using a higher fuse may damage
your amplier and will void your warranty.

9. +12Volt Positive Terminal: The +12Volt positive terminal is
designed to accept up to 8 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 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 amplier.
10. 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.

Power Connection
For maximum current ow, Aunex recommends that you tin your
ground wire before connecting it to the ground terminal of your
amplier. In addition, Aunex recommends using high quality 100%
OFC (Oxygen Free Copper) or Tinned 100% OFC speaker wire.
This will ensure that your speaker / subwoofer receives maximum
output from your amplier.
11. Ground: The Ground terminal is designed to accept up to 8
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.
