OWNER'S MANUAL

INTRODUCTION

THANK YOU for purchasing a JBL

®

 GX-A422SI amplifier. So we can better serve you should you require warranty service, please retain your original 

sales receipt and register your amplifier online at www.jbl.com.

INCLUDED ITEMS

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.

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.

Engli

sh

Amplifiers need air circulation to stay cool. Select a location that provides enough air for the amp to cool itself.
 • 

 

Suitable locations are under a seat (provided the amplifier doesn’t interfere with the seat adjustment mechanism), in the trunk, or in any other 

location that provides enough cooling air.

  • Do not mount the amplifier with the heatsink facing downward, as this interferes with the amplifier’s convection cooling.
  • Mount the amplifier so that it will not be damaged by the feet of backseat passengers or shifting cargo in the trunk.
  • Mount the amplifier so that it remains dry – never mount an amplifier outside the car or in the engine compartment.

NOTE : You may find it more convenient to make all of the connections to the amplifier before you permanently mount it to the vehicle.

1. Select a suitable mounting location as described above.
2. Using the amplifier as a template, mark the locations of the mounting holes on the mounting surface.
3. Drill pilot holes in the mounting surface.
4.  Attach the amplifier to the mounting surface with four appropriate mounting screws of your own choice. We suggest using #8 Phillips-head sheet 

metal screws. Make sure the amplifier is mounted securely.
