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

•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

•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(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.

Fuse Rating
When replacing fuses, make sure new fuse
is the correct type and amperage. Using an
incorrect fuse could damage the amplifier.
AX550D 40A x 1
Power/Ground Wire Size
For optimum performance, use only the wire
size listed below or larger. Make sure to use
the same size power and ground wire.
AX550D 4 Ga.
Main Power Connections
Connect +12V, GND and REM wires accordingly. A suitable fuse MUST be installed
on the +12V lead within 18" of the battery for protection of the vehicle’s electrical
system.

INSTALLATION
High-Level Input
(speaker cables)
Low-Level Input
(RCA)
Speaker Connections
Connect speaker wires observing polarity. The minimum impedance load for the
AX550D is 2 ohms stereo and 2 ohms mono. Use of loads lower than these is not
recommended and may cause amplifier damage.
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.
