INSTALLATION
WARNING: Playing loud music in an automobile can hinder your ability to hear traffic and permanently damage your hearing. We recommend listening at low or moderate levels while driving your car. JBL accepts no liability for hearing loss, bodily injury or property damage resulting from the use or misuse of this product.
IMPORTANT: To get the best performance from your JBL A6000GTi or A3000GTi amplifier, we strongly recommend that installation be entrusted to a qualified professional. Although these instructions explain how to install JBL amplifiers in a general sense, they do not show specific installation methods that may be required for your particular vehicle. If you do not have the necessary tools or experience, do not attempt the installation yourself. Instead, please ask your authorized JBL car audio dealer about professional installation.
•At the installation sites, locate and make a note of all fuel lines, hydraulic brake lines, vacuum lines and electrical wiring. Use extreme caution when cutting or drilling in and around these areas.
•Before drilling or cutting holes, use a utility knife to remove unwanted fabric or vinyl to keep material from snagging in a drill bit.
•When routing cables, keep input- signal cables away from power cables and speaker wires. Use grommets when passing cables through the vehicle’s inner walls.
•When making connections, observe the amplifier’s polarity markings. Make sure that each connection is clean and properly secured. Use the shortest ground wire possible to minimize resistance and avoid noise problems.
•If the amplifier’s fuse must be replaced, use only the same type and rating as that of the original. Do not substitute another kind.
WARNING: To avoid personal injury and possible product damage, we strongly urge you to enlist additional help in unpacking and moving the JBL A6000GTi or A3000GTi amplifier to a desired mounting location.

INSTALLATION WARNINGS AND TIPS
•Always wear protective eyewear when using tools.
•Turn off all audio components and other electrical devices before you start. Disconnect the
•Check clearances on both sides of a planned mounting surface before drilling holes or installing screws.
Remember – the screws can extend behind the surface.
CHOOSING A MOUNTING LOCATION
The JBL A6000GTi and A3000GTi amplifiers are big! Conventional mounting locations under driver or passenger seats will not accommodate either amplifier. Mount the amplifier in the vehicle’s trunk or cargo area, but never mount the amplifier in the engine compartment, outside the vehicle or in any location where it may get wet. When choosing a location, make sure the site’s underlying structure is strong enough to support the amplifier’s weight and drilled holes for mounting bolts. Also, verify that there will be adequate ventilation around the amplifier, so that airflow to its internal fans will not be blocked and the unit can properly cool itself.
