guideline only.
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
+12Vwirefromthebatterytotheamplifierlocation.Useagrommetwhenrunning
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
sectionofmetalorthevehiclechassiswhenattachingthegroundconnection.Be
sure to clean the area of any dirt or grease.
Remote Turn-on Wire (REM)

antenna output.
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.
Input Signal
•Theamplifier'sinputsignalconnectstotheheadunit'slowlevel(RCA)orhighlevel
(speakerwire)outputs.
•Lowlevelinputsignaldeliverthebestperformance.Ifunavailable,usethehigh
levelinputs-wheninterfacingwithfactoryheadunitforinstance.
CAUTION
•Donotusebothlowandhighlevelinputsatthesametime-connectonlyoneor
