3. AMPLIFIER MOUNTING
Attention!Foryourownsafety,disconnectthenegativebatteryterminal(GND)orremove
themainfuseinthepositivepowercablenearthecarbattery,beforeyoustartanywiring
work!
BeforeyouproceedtoinstallthisAXTONamplier,itisrecommendedtomapoutthe
completesystemandtherespectivewiringrequired.Consideralladditionalelectrical
requirementsandaccessories,suchaspowercables,interconnectcablesetc.,tocomplete
theinstall.Pleasenotethat-becauseofpossibleinterferenceproblemswiththeexistingcar
electricsandelectronics,especiallytheroutingofthesignalcablesandthechassisground
connectionwillhaveaprofoundimpactonthetrouble-free(noisefree!)operationofthe
amplier.
Themountinglocationshouldbecarefullyselectedandintheinterestofpassivedriverand
passengersafety,theampliermustbesecurelymounted.Makesurethatthereisnowiring
harness,fueltanketc.behindorbelowthemountingsurfacethatmaybedamagedbythe
drillingoftheholesfortheampliermountingscrews.Afterinstallation,thereshouldbea
clearanceofatleast5cmtoallsidesincludingthetopoftheamplierheatsink.Makesure
theunitisnotexposedtodirectsunlight,humidity,water,oilorspillofotheruidsthatmay
entertheamplier.
Oncethelocationwheretheamplierwillbemountedisdetermined,usetheunitasa
template for the marking of the mounting holes with pencil or felt-tip marker. The mounting
holesshouldbepilot-drilled,usinga2,5mmor3mmdrillbit.Bolttheampdown.
Important! There must not be a direct contact of the amplier heatsink, bottom panel
or any other metal part of the amplier to the vehicle metal panel! Electrical ground-
loops will cause audible hum!
4. WIRE ROUTING
4.1 MAIN POWER WIRES
Werecommendaminimummainpowercablecross-section(5mtotallength)of10to
16mm²,forboththepositiveandthegroundwires.Followingtheserecommendations
guaranteesatrouble-freeoperationofyouramplier,aswellasfullpoweroutput.
Runthepositivemainpowercable(„+12V“)directlyfromthepositiveterminalofthe
carbatterytotheamplier.Forprotectionofyourcaraudiosystemagainstelectricalre
hazards,resultingfromashort-circuitofthemainpowercabletochassisgroundamain
fuseholdermustbeinsertedwithintherst30cmofthepositivemainpowercable.The
applicablefusevaluemustbematchedtothelimitationsofyourmainpowercableandthe
currentdrawoftheamplier–thereforechooseanappropriatefusevalue.
Attachthegroundcabletotheamplier.Inmostcasesitwillbebesttokeeptheground
cable(„-12V“)asshortaspossible,i.e.tondachassiscontactveryclosetotheamplier.
Thegroundpowerwiremusthavethesamecross-sectionasthepositivepowercable.The
contactpointwherethegroundwireisattachedto,mustbesolidandclean,i.e.freefrom
rustorpaint!
Tightenbothpowerinputterminalsoftheamplier,anddoublecheckforperfecttofboth
maincableleads!
4.2 RCA & REMOTE WIRES
Forbestinterferencefreetransmissionofthemusicsignal,usedoubleortripleshielded
RCAinterconnectsonly.TwistedpairInterconnectsofferexcellentnoiserejectionaswell.
RoutetheRCAinterconnectsawayfrompotentialsourcesofInterference,suchasengine
computers, gas pumps, etc.
Carefullyruntheaudiosignalinterconnects,theremotewireand–ifapplicable-thecable
ofthelowpasslevelremotecontrol(A1300only)fromtheheadunitordashboardtothe
amplier.Asmentionedbefore,theaudiosignalcablesshouldalwaysberoutedcompletely
separatefromthepowercables.Connecttheremote(turnon/turnoff)leadtotherespective
inputterminaloftheamplierandtotheremoteoutputofyourhead-unit.Nowyoucan
connecttheRCAinterconnectstotherespectiveoutputsofyourhead-unitandtotheinputs
oftheamplier.Payattentiontoconnectthestereointerconnectscorrespondingly,leftis
1CH,rightisalways2CHa.s.o.
4.3 LOUDSPEAKER WIRES
Forlongerdistancestothespeakers,itisbesttouse1.5mm
2
or 2.5 mm
2
speakercablesto
avoidalossofpowerorriskdegradationofthesignalquality.
Oncethespeakercableshavebeenrouted,turnloosethescrewsofthespeakerterminal
bindingpostsand–afterinsertingthestrippedandbarespeakercableends–re-tightenthe
screws.Maintaincorrectpolarity(„+“to„+“;„-„to„-„).
Closetheelectricalcircuitbyattachingthegroundwiretothebatteryandswitchonyour
headunit.ThestatusbarbelowtheAXTONlogoshouldturnon.Ifthestatusbardoesnot
illuminate,yourinstallationiswrong!Immediatelyturnoffyourhead-unitandcarefullyre-
checkallinstallationandwiringsteps!
