INSTALLATION
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.
Before You Start
•Disconnectnegativebatteryterminal.(consultaqualifiedtechnicianforinstructions)
•Avoidinstallingtheamplifierwhereitwouldbesubjecttohightemperatures,suchas
fromdirectsunlight,orwhereitwouldbesubjecttodust,dirtorexcessivevibration.
•Useextremecautionwhendrillingholestoavoiddamagingfuellinesorexistingvehicle
wiring.
•Allamplifierinstallationsrequirepower,signalandspeakerwires(notincluded).
•Anamplifierinstallationkit(soldseparately)ishighlyrecommendedtofacilitatethe
installation. Consult your dealer for recommendations.
Mounting Location
•Chooseamountinglocationfortheamplifier.Suggestedlocationsincludeunderaseat
orinthetrunk.
•Theamplifiercanbemountedhorizontal(recommended)orvertical.Foroptimum
performance,makesuretoprovideatleast1"ofspacearoundallsides.Donotmount
theamplifierundercarpetsorwhereairflowisrestricted.
•Donotinstalltheamplifierwhereitmaybeexposedtomoisture.
•Theoptimummountinglocationvariesbetweenvehicles.Remembertotestallamplifier
functions before completing the final mounting procedure.
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.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.
•Neverrunanywiresunderneathoroutsidethevehicle.

Amplifier Connections
Speaker Connections
Connectspeakerwiresobserving
polarity. Theminimumimpedance
load for the AXA20 and AXA40D
is 2 ohms stereo and 4 ohms
bridged.Useofloadslowerthan
these is not recommended and
maycauseamplifierdamage.The
AXA20andAXA40D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.

Configuration/Setup
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crossover
frequency.
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designedtohandle.
