Preparation
Please read entire manual before installation. Due to the technical nature of
amplifiers, it is highly recommended that your Axxera amplifier is installed by a
professional installer or an authorized dealer.

TYPICAL MOUNTING METHOD

NOTE:
Be sure to follow specific instructions included with your amplifier installation
kit (not included with this amplifier). The information below should be used as a
general guideline only.
Power Wire (+12V)
•Disconnectnegativebatteryterminalbeforeproceeding.Consultaqualified
technician for instructions if you are unsure.
•Planwireroutingbeforecuttinganywirestolength.Beginbyroutingthepower
+12Vwirefromthebatterytotheamplifierlocation.Useagrommetwhenrunning
wiresthroughthefirewallormetalopenings.Avoidrunningthepowerwirenear
existingvehiclewiringtopreventinducednoisefromenteringtheaudiosystem.
•Useextremecautionwhendrillingholestoavoiddamagingfuellinesorexisting
vehiclewiring.
•The+12VwireMUSTbefusedwithin18"ofthebatteryforprotectionofthe
vehicle’selectricalsystem.
Ground Wire (GND)
•Theamplifiergroundwireshouldbeasshortaspossible(nomorethan36"or
1meter).Chooseacleanunpaintedsectionofmetalorthevehiclechassiswhen
attachingthegroundconnection.Besuretocleantheareaofanydirtorgrease.
Remote Turn-on Wire (REM)
•Theremoteturn-onwireconnectstotheheadunit'samplifierturn-onleadorpower
antenna output.
Speaker Wires
•Chooseadequategaugespeakerwiredependingonyourexactamplifier/speaker
combination.Besuretoobservepolaritywhenconnecting.
•Donotgroundanyspeakerwiresorconnectanyspeakerwirestogether.
Input Signal
•Theamplifier'sinputsignalconnectstotheheadunit'slowlevel(RCA)orhighlevel
(speakerwire)outputs.
•Lowlevelinputsignalsdeliverthebestperformance.Ifunavailable,usethehighlevel
inputs-wheninterfacingwithfactoryheadunitforinstance.
CAUTION
•Donotusebothlowandhighlevelinputsatthesametime.Connectonlyoneorthe
other.
•Keeplowlevelinputsawayfromanypowerwirestoavoidenginenoise.
•Neverrunanywiresunderneathoroutsidethevehicle.

High-Level Input
(speaker cables)
Low-Level Input
(RCA)
Speaker Connections
Connect speaker wires
observing polarity. The minimum
impedance load for the AX260,
AX440, AX460 and AX490
is 2 ohms stereo and 4 ohms
bridged. Use of loads lower than
these is not recommended and
may cause amplifier damage.
The AX260, AX440, AX460 and
AX490 can be wired for stereo,
bridged or stereo/bridged
simultaneous operation.
Input Signal Connections
Low Level Input (RCA)
Low level (RCA) input signal is preferred for best performance. Typical trunk-mount
amplifier installations require a 17-20 foot RCA cable. Most trucks and under-seat
applications require a 6-9 foot RCA cable. Using twisted pair construction RCA cables
will minimize noise.
High Level Input
(Speaker Wire)
High level inputs should only be used
when RCA outputs are not available
from the head unit. Connect the
head unit speaker outputs to
the high level input connector
as shown below. The black wire
(signal reference ground)may or
may not require a connection to
chassis ground - depending on your
particular installation.

Note: Do not use both low and high level inputs
at the same time - connect only one or the other.

Connecting Two Amplifiers - Bridge Mode
Master/Slave Mode
The Dual mono amplifiers feature a Master/Slave mode, where two amplifiers can be
connected together. When two mono amplifiers are connected together, the power
from both amplifiers is combined.

INSTALLATION
Connecting Two Amplifiers - Bridge Mode
*MASTER
For master amplifier, set the switch to master. This will route the signal through Line-out to
the slave amplifier. Set the phase to 0, all adjustments for gain and sound are done on this
amplifier. The remote subwoofer control should be connected to master amplifier as well.
*SLAVE
For slave amplifier, set the switch to slave and phase to 180. Connect the Line-out of master
amplifier to input on this amplifier. All adjustments should be set to minimum.
Connect Data-Link plug from master to slave amplifier. For speaker connection, the positive
(+) of the speaker connects to positive (+) of master and negative (-) of the speaker connects to
positive (+) of slave amplifier. Connect both negatives (-) of master and slave each other.
NOTE: FOR BEST PERFORMANCE, USE WIRE 12 AWG OR THICKER FOR THE NEGATIVE TO
NEGATIVE CONNECTION.
*MINIMUM IMPEDANCE MUST NOT BE LOWER THAN 2 OHMS

Theinputlevelcontrol(gain)isusedtoobtainthe
bestpossiblematchbetweentheheadunitaudio
outputandtheamplifierinput.Beginbyturningthe
inputlevelcontrolfullycounterclockwise.Next,turn
uptheheadunitvolumecontrolaround3/4of
thewayup.Adjusttheinputlevelcontrolclockwise
until audible distortion is heard, then slightly
counterclockwisetoprovidethebestmatch.
Repeatforallinputlevelcontrols.
Thecrossoverisusedtofilteroutfrequencies
aboveorbelowacertainpoint.ChooseLPFwhen
usingtheamplifierwithsubwoofers,HPFwhen
usingwithmidrange/tweetercombinationsand
FLATwhenusingwithcoaxial-typespeakers.
Note: Choose FLATwhenusingtheamplifierin
stereo/bridgedsimultaneousmode.Inthismode,
passivecrossoversarerequired.Failuretouse
thecorrectpassivecomponentsmaydamage
theamplifierand/orspeakers.Consultaqualified
professional for recommendations.
Thiscontrolallowspreciseadjustmentofthe

Thiscontrolprovidesadditionalboost@45Hzwhen
usedwithsubwoofers.Adjustthiscontrolwith
caution-asimproperusecandamagespeakers!
Settingthiscontroltothedesiredfrequencywill
limitharmfulfrequenciesbelowthesettingfrom
goingtothesubwoofer(s),preventingpossible
damagefromfrequenciesthatsubwoofersarenot
