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

• Suitablelocationsareunderaseat(providedtheamplifierdoesn’tinterferewiththeseatadjustmentmechanism),inthetrunk,orinanyother location that provides enough cooling air.

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.

The GX series amplifiers are capable of delivering high power levels, and require a heavy-duty and reliable connection to the vehicle’s electrical systemtoachieveoptimalperformance.Pleaseadheretothefollowinginstructionscarefully. usIng the connectors GX-series amplifiers use the same type of screw terminals for power and speaker connections. This type of terminal is easy to use and allows the easy connection of large-gauge wire.
