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.

If your amplifier isn’t performing the way you think is should, check to see if the problem is covered in this section before calling your dealer or
contacting JBL customer service.
PROBLEM CAUSES AND SOLUTIONS
Nosound(theamplifier’sPowerLEDisoff) • Checkthattheamplifier’s+12VandGNDconnectionshavebeenproperlymade.
• Checkifthefuseonthe+12Vwirelocatednearthebatteryisblown:Ifso,replaceitwithan
identical fuse.
• Checkallamplifierfuses;ifanyareblown,replacethemwithidenticalfuses.
• Ifyouareusingtheamplifier’sREMconnectionforturn-on,checkthatthewireisproperly
connectedtotheaudiosystem’sremoteturn-onwireortothevehicle’sACCpowerterminal.
Nosound(theamplifier’sPowerLEDisorange) •Checkthatallamplifierinputandspeakerconnectionshavebeenproperlymade.
• Checkthattheamplifier’sLevelcontrolsarenotturnedallthewaydown(counter-clockwise).
• Checkthatthevehicleaudiosystem’ssourceunit’svolumecontrolisnotturnedalltheway
down.
Nosound(theamplifier’sProtectionLEDisred) •Confirmthatthevehicle’selectricalsystemissupplyingbetween9Vand16VDCtothe
amplifier. If the supply voltage is outside of this range, correct the condition before attempting to
use the amplifier.
• Iftheamplifierhasoverheated,waituntilithascooleddownbeforeattemptingtouseitagain.
• Disconnectallspeakersfromtheamplifierandattempttoturnitonagain:
– Iftheamplifierturnson(thePowerLEDisorange),thereisashortcircuitinoneormoreofthe
speakerwires.Correctallshortcircuitsbeforereconnectingthespeakerstotheamplifier.
– Iftheamplifierdoesnotturnon(theProtectionLEDisstillredandthePowerLEDisoff),
contact your authorized JBL dealer for assistance.

PROBLEM CAUSES AND SOLUTIONS
Sound only comes from some of the speakers
connected to the amplifier
• Checkthatthevehicleaudiosystem’ssourceunit’sbalanceandfadercontrolsaresettotheir
center (midpoint) positions.
• (GX-A604):Checkthatthesettingoftheamplifier’sModeSwitchmatchestheinputandspeaker
connections made to the amplifier
Sound is too quiet, even with the vehicle audio
system’s source unit volume all the way up
• Checkthattheamplifier’sLevelcontrolsarenotturnedtoolow.SeeSet The Input Level, on
page 22, for information about setting the Level controls.
Sound in the front/rear speakers is distorted • Makesuretheamplifier’sCrossoverFilterswitchforthedistortedchannelsissettoHP.
• SettheCrossovercontrolforthedistortedchannelstoahighersetting.
• Checkthatthedistortionisnotoriginatingfromthevehicleaudiosystem’ssourceunit.
Sound in the subwoofer is distorted • (GX-A604,GX-A602):SettheBassBoostswitchto"OFF".
• (GX-A3001):Whilelisteningtobass-heavymusic,turntheBassBoostcontrolallthewaydown,
and then gradually increase it until the distortion begins to return. Reduce the Bass Boost
control setting slightly to eliminate the distortion and leave it set there.
• Checkthatthedistortionisnotoriginatingfromthevehicleaudiosystem’ssourceunit.
