Putthe screws in a safe place, so you can use them to reattach the end caps after you have made all the connections tothe amplifier.nOte: Before you permanently mount the amplifier, read Auto Turn-On Switch, below, to determine the setting of theswitch, 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. Wesuggest using #8 Phillips-head sheet metal screws. Make sure the amplifier is mounted securely.cOnnecTiOnsimpOrtant: 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 inMounting the Amplifier, above. This will provide easier access to all of the amplifier’s connectors.autO turn-On sWitchNo remote turn-on connection is necessary because GTO amplifiers include signal-sensing turn-on, which will turnthe amplifier on when it receives an audio signal at any of its input connectors. The amplifier will automatically turn offapproximately 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 amplifierwill sense that you’ve used a remote turn-on wire and that connection will override the signal-sensing turn-on. Ifnecessary, you can defeat the signal-sensing turn-on circuit by moving the Auto Turn-On switch to the “Off” position.
