LOCATION AND MOUNTING

Although these instructions explain how to install GX-series amplifiers in a general sense, they do not show specific installation methods that may be

required for your particular vehicle. If you do not have the necessary tools or experience, do not attempt the installation yourself. Instead, please ask

your authorized JBL car audio dealer about professional installation.

InstallatIon WarnIngs and tIps

IMPORTANT: Disconnect the vehicle’s negative (–) battery terminal before beginning the installation.

 •Alwayswearprotectiveeyewearwhenusingtools.

 •Checkclearancesonbothsidesofaplannedmountingsurface.Besurethatscrewsorwireswillnotpuncturebrakelines,fuellinesorwiring

harnesses, and that wire routing will not interfere with the safe operation of the vehicle.

 •Whenmakingelectricalconnections,makesuretheyaresecureandproperlyinsulated.

 •Ifyoumustreplaceanyoftheamplifier’sfuses,besuretousethesametypeoffuseandcurrentratingasthatoftheoriginal.

INSTALLATION LOCATION

Amplifiers need air circulation to stay cool. Select a location that provides enough air for the amp to cool itself.

•Suitablelocationsareunderaseat(providedtheamplifierdoesn’tinterferewiththeseatadjustmentmechanism),inthetrunk,orinanyother

location that provides enough cooling air.

•Donotmounttheamplifierwiththeheatsinkfacingdownward,asthisinterfereswiththeamplifier’sconvectioncooling.

•Mounttheamplifiersothatitwillnotbedamagedbythefeetofbackseatpassengersorshiftingcargointhetrunk.

•Mounttheamplifiersothatitremainsdry–nevermountanamplifieroutsidethecarorintheenginecompartment.

MOUNTING THE AMPLIFIER

NOTE: You may find it more convenient to make all of the connections to the amplifier before you permanently mount it to the vehicle.

1. Select a suitable mounting location as described above.

2. Using the amplifier as a template, mark the locations of the mounting holes on the mounting surface.

3. Drill pilot holes in the mounting surface.

4.Attachtheamplifiertothemountingsurfacewithfourappropriatemountingscrewsofyourownchoice.Wesuggestusing#8Phillips-headsheet

metalscrews.Makesuretheamplifierismountedsecurely.

POWER AND GROUND CONNECTIONS

IMPORTANT: Disconnect the vehicle’s negative (–) battery terminal before beginning the installation.

The GX series amplifiers are capable of delivering high power levels, and require a heavy-duty and reliable connection to the vehicle’s electrical

systemtoachieveoptimalperformance.Pleaseadheretothefollowinginstructionscarefully.

usIng the connectors

GX-series amplifiers use the same type of screw terminals for power and speaker connections. This type of terminal is easy to use and allows the

easy connection of large-gauge wire.

Tousetheconnectors,useaPhillipsscrewdrivertoloosentheconnector’ssetscrew,insertthebarewireandtightenthesetscrewtosecurethe

wire in the connector, as shown in the illustration below.

IMPORTANT: Makesurethe(+)and(–)speakerbarewiresdonottoucheachotherortheotherterminalatboththeamplifierterminalsandspeaker

terminals. Touching wires can cause a short circuit that can damage the amplifier.

GROUND (GND) CONNECTION

Connectawire(minimum10AWG–5.3mm2)

from the amplifier’s GND terminal directly to a

solid point on the vehicle’s chassis.

•Foragoodconnection,usesandpapertoclear

the paint from the metal surface at this chassis

location. Use a star-type lock washer to secure

the wire’s connection.

POWER (12 V) CONNECTION

1.Connectawire(minimum10AWG–5.3mm2)

directlytothebattery’spositive(+)terminal.

2.Installafuseholderfora50Afuse(GX-A604,

GX-A3001)ora30Afuse(GX-A602)onthis

wirewithin18"(46cm)ofthebattery’s(+)

terminal. Do not install the fuse in the holder

at this time.

3. Route this wire to the amplifier’s location and

connectittotheamplifier’s+12Vterminal.

Be sure to use appropriate grommets

whenever routing wires through the firewall

or other sheet metal. IMPORTANT: Failure

to adequately protect the positive wire from

potential damage may result in a vehicle fire.

4.Whenyouarefinishedroutingandconnecting

this wire, install the appropriate fuse in the

holder you installed near the battery.
