PreparationPlease read entire manual before installation. Due to the technical nature of amplifiers, it is highly recommended that your DUAL amplifier is installed by a professional installer or an authorized dealer.

Before You Start•Disconnectnegativebatteryterminal.(consultaqualifiedtechnicianforinstructions)•Avoidinstallingtheamplifierwhereitwouldbesubjecttohightemperatures,suchasfromdirectsunlight,orwhereitwouldbesubjecttodust,dirtorexcessivevibration.•Useextremecautionwhendrillingholestoavoiddamagingfuellinesorexistingvehiclewiring.•Allamplifierinstallationsrequirepower,signalandspeakerwires(notincluded).•Anamplifierinstallationkit(soldseparately)ishighlyrecommendedtofacilitatethe

installation. Consult your dealer for recommendations.

Mounting Location•Chooseamountinglocationfortheamplifier.Suggestedlocationsincludeunderaseatorinthetrunk.•Theamplifiercanbemountedhorizontal(recommended)orvertical.Foroptimumperformance,makesuretoprovideatleast1"ofspacetoaroundallsides.Donotmounttheamplifierundercarpetsorwhereairflowisrestricted.•Donotinstalltheamplifierwhereitmaybeexposedtomoisture.•Theoptimummountinglocationvariesbetweenvehicles.Remembertotestall

amplifier functions before completing the final mounting procedure.

TYPICAL MOUNTING METHOD

Note: Besuretofollowspecificinstructionsincludedwithyouramplifierinstallationkit(notincludedwiththisamplifier).Theinformationbelowshouldbeusedageneralguideline only.

Power Wire (BAT+)

•Disconnectnegativebatteryterminalbeforeproceeding.Consultaqualifiedtechnician for instructions if you are unsure.

•Planwireroutingbeforecuttinganywirestolength.Beginbyroutingthepower+12Vwirefromthebatterytotheamplifierlocation.Useagrommetwhenrunningwiresthroughthefirewallormetalopenings.Avoidrunningthepowerwirenearexistingvehiclewiringtopreventinducednoisefromenteringtheaudiosystem.

•Useextremecautionwhendrillingholestoavoiddamagingfuellinesorexistingvehiclewiring.

•The+12VwireMUSTbefusedwithin18"ofthebatteryforprotectionofthevehicle’selectrical system.

Ground Wire (GND)

•Theamplifiergroundwireshouldbeasshortaspossible.Chooseacleanunpaintedsectionofmetalorthevehiclechassiswhenattachingthegroundconnection.Besure to clean the area of any dirt or grease.

Remote Turn-on Wire (REM)

•Theremoteturn-onwireconnectstotheheadunit'samplifierturn-onleadorpowerantenna output.

Speaker Wires

•Chooseadequategaugespeakerwiredependingonyourexactamplifier/speakercombination.Besuretoobservepolaritywhenconnecting.

•Donotgroundanyspeakerwiresorconnectanyspeakerwirestogether.

Input Signal

•Theamplifier'sinputsignalconnectstotheheadunit'slowlevel(RCA)orhighlevel(speakerwire)outputs.

•Lowlevelinputsignaldeliverthebestperformance.Ifunavailable,usethehighlevelinputs-wheninterfacingwithfactoryheadunitforinstance.

CAUTION

•Donotusebothlowandhighlevelinputsatthesametime-connectonlyoneor the other.

•Neverrunanywiresunderneathoroutsidethevehicle.
