Mounting the Amplifier

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

Before mounting the amplifier you must remove the two end caps to expose the mounting holes and the connections. Using a Phillips screwdriver, remove the attachment screws and then the end caps, as shown in the illustration. Put the screws in a safe place, so you can use them to reattach the end caps after you have made all the connections to the amplifier.

NOTE: Before you permanently mount the amplifier, read Auto Turn-On Switch, below, to determine the setting of the switch, which is located on the amplifier’s bottom panel.

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.

Connections

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

If you have not already done so, remove the two end caps that cover the amplifier’s connectors as explained in

Mounting the Amplifier, above. This will provide easier access to all of the amplifier’s connectors.

Auto Turn-On Switch

No remote turn-on connection is necessary because GTO amplifiers include 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 Auto Turn-On switch to the “Off” position.
