important: Disconnect the vehicle’s negative (–) battery terminal before beginning the installation.

The GX series amplifiers are capable of delivering high power levels, and require a heavy-duty and reliable connection to the vehicle’s electrical system to achieve optimal performance. Please adhere to the following instructions carefully.

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.

To use the connectors, use a Phillips screwdriver to loosen the connector’s set screw, insert the bare wire and tighten the set screw to secure the wire in the connector, as shown in the illustration below.

IMPORTANT: Make sure the (+) and (–) speaker bare wires do not touch each other or the other terminal at both the amplifier terminals and speaker

terminals. Touching wires can cause a short circuit that can damage the amplifier.
