LOCATION AND MOUNTING
Although these instructions explain how to install the GX-A422SI 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.
INSTALLATION WARNINGS AND TIPS
IMPORTANT: Disconnect the vehicle’s negative (–) battery terminal before beginning the installation.
• Always wear protective eyewear when using tools.
•
Check clearances on both sides of a planned mounting surface. Be sure that screws or wires will not puncture brake lines, fuel lines or wiring
harnesses, and that wire routing will not interfere with the safe operation of the vehicle.
• When making electrical connections, make sure they are secure and properly insulated.
• If you must replace any of the amplifier's fuses, be sure to use the same type of fuse and current rating as that of the original.
