Preparation

Please 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

•Disconnectnegativebatteryterminal.(consultaqualifiedtechnicianforinstructions)

•Avoidinstallingtheamplifierwhereitwouldbesubjecttohightemperatures,suchas

fromdirectsunlight,orwhereitwouldbesubjecttodust,dirtorexcessivevibration.

•Useextremecautionwhendrillingholestoavoiddamagingfuellinesorexisting

•Anamplifierinstallationkit(soldseparately)ishighlyrecommendedtofacilitatethe

installation. Consult your dealer for recommendations.

Mounting Location

•Chooseamountinglocationfortheamplifier.Suggestedlocationsincludeunderaseat

orinthetrunk.

•Theamplifiercanbemountedhorizontal(recommended)orvertical.Foroptimum

performance,makesuretoprovideatleast1"ofspacetoaroundallsides.Donot

mounttheamplifierundercarpetsorwhereairflowisrestricted.

•Donotinstalltheamplifierwhereitmaybeexposedtomoisture.

•Theoptimummountinglocationvariesbetweenvehicles.Remembertotestall

amplifier functions before completing the final mounting procedure.

TYPICAL MOUNTING METHOD

Note: Besuretofollowspecificinstructionsincludedwithyouramplifierinstallation

kit(notincludedwiththisamplifier).Theinformationbelowshouldbeusedageneral

Power Wire (BAT+)

•Disconnectnegativebatteryterminalbeforeproceeding.Consultaqualified

technician for instructions if you are unsure.

•Planwireroutingbeforecuttinganywirestolength.Beginbyroutingthepower

wiresthroughthefirewallormetalopenings.Avoidrunningthepowerwirenear

existingvehiclewiringtopreventinducednoisefromenteringtheaudiosystem.

•Useextremecautionwhendrillingholestoavoiddamagingfuellinesorexisting

vehiclewiring.

•The+12VwireMUSTbefusedwithin18"ofthebatteryforprotectionofthevehicle’s

electrical system.

Ground Wire (GND)

•Theamplifiergroundwireshouldbeasshortaspossible.Chooseacleanunpainted

Speaker Wires

•Chooseadequategaugespeakerwiredependingonyourexactamplifier/speaker

combination.Besuretoobservepolaritywhenconnecting.

•Donotgroundanyspeakerwiresorconnectanyspeakerwirestogether.
