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

•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
