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.
