Mounting

Appropriatemountingisveryimportantfortheprolongedlifeexpectancyofanyamplier.Selectalocationthatallowsenough

spacesosucientairowismaintainableandalocationthatprovidesprotectionfrommoisture.Keepinmindthatanamplier

shouldneverbemountedupsidedown.Upsidedownmountingwillcompromiseheatdissipationthroughtheheatsinkand

couldengagethethermalprotectioncircuit.Excessiveheatwillshortenyouramplierslife.Tomaximiseheatdissipation,be

suretoleaveatleast2.5”ofclearancearoundtheamplier.Ifspaceisoftheessenseandtheampliermustbemountedin

ToavoidscratchingyournewFUSIONamplier,pre-drillthemountingholeswitheithera3mmor9/64”diameterdrillbitanduse

thescrewssuppliedintheaccessorykit.Besuretoinvestigateyourmountingareathoroughlytoavoidelectricalwires,vacuum

Installation Options

ThequalityofinstallationwillaecttheperformanceandreliabilityofyourFUSIONamplier.Formaximumperformancewe

recommendyouhaveyournewFUSIONamplierinstalledbyanauthorisedFUSIONdealer.Ourhighlyskilleddealershavevast

knowledgeofourproductsandtheirinstallationtechniquesarenecessarytounleashthehighperformancecapabilitiesofyour

amplier.

Ifyoudecidetoconnecttheamplieryourself,itisimportantthatyoureadthismanualcarefullyandthroughoutbeforestart-

ing.Onceyouhavenishedreadingandyoustillhavequestionsregardinginstallation,werecommendyourFUSIONdealer.

Connection

FUSIONampliersaredesignedtoworkwithina10to16voltDCrange.Beforeanywiresareconnected,thevessel’selectrical

systemshouldbecheckedforcorrectvoltagesupplywiththehelpofavoltmeter.First,checkthevoltageatthebatterywiththe

ignitionintheOFFposition.Thevoltmetershouldreadbetween12and13.8Volts.Ifyourvehicle’selectricalsystemisnotupto

thesespecication,werecommendhavingitcheckedbyanautoelectricianbeforeanyfurtherinstallation.Oncethevesselis

checked,makecertainthecorrectcablesizeisused.Werecommendusingthefollowingcablescalculatordiagramonpage8to

calculatethecorrectpowercableforyourapplication.

Power

FUSIONampliersshouldbewireddirectlytothebatteryusingtheappropriatesizedcable.Startatthevehiclebatteryandrun

thepowercablethroughtotheamplier.FUSIONrecommendstheuseofgrommetswhenpassingthepowercablethroughany

metalwalltoavoidsharpcornersorsharpbodypartsthatmayeasilycutthroughtheinsulationonthecable.

Avoidrunningthepowercableoverenginecomponentsandnearheatercores.Theuseofaninlinefuseorcircuitbreakeris

amust,thiswillpreventtheriskofapotentialrecausedbeashortinyourpowercable.Connectthefuseholderorcircuit

breakerasclosetothebatterypositiveterminalaspossible.Useafuseorcircuitbreakerofequalvalueasthatfoundonthe

chassisofyourFUSIONamplier.Youmaynowconnectthecabletothebattery,butremembertoleavethefuseoutorcircuit

breakerountilallothercableconnectionsaremade.

Ground

WhengroundingyourFUSIONamplier,locateametalareaclosetotheamplierthatisagoodsourceofground.Onceagain,

investigatetheareayouwishtouseforelectricalwires,vacuumlines,andbrakeorfuellines.Useeitherawirebrushorsand-

papertoeliminateunwantedpaint.Thiswillsupplyabettercontactforyourground.Usethesamegaugecableforgroundas

youdidforthepower.Securethegroundcabletotheappropriategroundpointusingabolt,starwasherandnut.Spreadsilicon

overthescrewandbaremetaltopreventrust.Nowitstimetoconnectthepowerandgroundcablestotheamplier.Cutboth

cablestolength.Crimptheyellowspadeconnectorssuppliedtothepowerandground.Useahextypescrewdrivertoloosenthe

+12VandtheGNDconnectionsontheamplier.Terminatethegroundrst,andthenthe+12Vandpleasemakesurethatyou

terminatethemintothecorrectterminals.Thentightenthescrewsdownsecurely.

Speaker Load

KeepinmindFUSION‘FM’seriesampliersarehighpowerampliersandnothighcurrentampliers.Inotherwordstheyrequire

aminimumimpedanceof2ohmsSTEREOand4ohmsbridgedMONOtooperatetroublefree.Toolowofanimpedancecouldsend

yourFUSIONamplierintoprotectionmodeand/ordamagetheamplier.

Remote Turn-on

Thisterminalmustbeconnectedtoaswitched+12Vsource.Typically,remoteturn-onleadsareprovidedattheheadunitwhich

willturnonandotheamplierincorrespondencewiththesource.Iftheheadunitdoesnothavearemoteturn-onlead,then

apowerantennawirecanbeused.Ifneitheroftheseleadsarepresentontheheadunitthenaswitched+12Vsupplymustbe

used,liketheACC+12V.

Runaminimumof18gaugewirefromtheamplierlocationtothesourceoftheswitched+12Vlead.Ifpossible,routethiswire

onthesamesideofthevehicleasyourpowercable.Connectthesourceremoteoutputtothewire.Gobacktotheamplierand

cutthewiretolength.LoosenthescrewterminalmarkedREMontheamplierusingahextypescrewdriver.Slipthewireinto

theconnectorandtightenthescrewsecurely.

Speaker Wiring

Choosethecorrectspeakerwireforyourapplication.Mostapplicationwillrequireaminimumof16gauge.Routetheseusingthe

sameprecautionsasyoudidwhenyouranthepowercables.Terminatethesewiresatthespeakerendusinginsulatedspeaker

terminals(notsupplied)orbysolderingtheconnection.Makesurethespeakerconnectionsarepositivetopositiveandnegative

tonegative.Attheamplierend,usea#2Phillipsscrewdrivertoloosenthespeakerterminalsontheamplier.Connectthe

speakerwiresandtightenthescrewssecurely.Checktomakesureyou’vemaintainedproperpolarityandbalance.

Inputs & Gain Setup

Low Level Inputs

BeextracarefulwithyourRCAinterconnects.Hiss,enginenoise,andfannoisecaneasilybepickedupthroughRCAcablesifrun

incorrectly.AvoidrunningyourRCAsnearlargewireloomsandelectricfansifpossible.RunyourRCAcablesontheoppositeside

ofthepowercable.Besuretocheckforcorrectbalance(Redisrightandblackorwhiteisleft)

Level Control

Ontheamplier,istheLEVELcontrol,thiscontrolallowsyoutomatchtheinputleveloftheampliertotheoutputlevelofyour

headunit.Matchingtheinputcanbeaccomplishedinthreesimplesteps:

1. TurntheLEVELcontrolontheampliertominimum.

2. Turnuptheheadunitandadjustto2/3maximumvolumeensuringthattheBASSandTREBLEaresettozero.

3. AdjusttheLEVELcontroluntilthedesiredvolumeisachievedwithoutaudibledistortion.

Remember,thegaincontrolisnotavolumecontrol.Ignoringthethreestepsabovemayleaveyouwithdamagedspeakersand/

oradamagedamplier.
