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 
guideline only.
Power Wire (+12V)
•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)
•Theremoteturn-onwireconnectstotheheadunit'samplifierturn-onleador
power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
the other.
•Neverrunanywiresunderneathoroutsidethevehicle.
