CONNECTIONS
IMPORTANT: Disconnect the vehicle's negative (–) battery terminal before beginning the installation.
The GTX500 amplifier is capable of delivering high power levels, and requires a heavy-duty and reliable connection to the vehicle’s electrical system
to achieve optimal performance. Please adhere to the following instructions carefully.
If you have not already done so, remove the two end caps that cover the amplifier’s connectors as explained in Mounting the Amplifier, on page 3.
This will provide easier access to all of the amplifier’s connectors.
AUTO TURN-ON SWITCH
No remote turn-on connection is necessary because the GTX500 includes signal-sensing turn-on, which
will turn the amplifier on when it receives an audio signal at any of its input connectors. The amplifier will
automatically turn off approximately five minutes after the input signal ceases.
If your audio system’s source unit includes a remote turn-on wire and you would prefer to use it, the
amplifier will sense that you’ve used a remote turn-on wire and that connection will override the signal-
sensing turn-on. If necessary, you can defeat the signal-sensing turn-on circuit by moving the amplifier's
Auto Turn-On switch to the “Off” position.
USING THE CONNECTORS
The GTX500 uses 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 to the
right.
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.
