Installation Basics
Before you begin your installation, disconnect the NEGATIVE(-) terminal from your vehicle’s battery. This safety precaution will avoid possible short circuits while wiring your amplifier.
Rockville amplifiers operate on 12-volt negative ground systems only. It is recommended that you layout your sound system design on paper first. This will help you during the
installation so that you will have a wiring flow chart and not miss-wire any of your components.
Mount the amplifier somewhere out of the way: at the rear of the boat, underneath the dashboard, or below the seats. Never install an amplifier in the engine compartment. Please be
sure to leave breathing room around the amplifier heat sink so that it can dissipate the heat it produces efficiently. The amplifier can be installed either horizontally or vertically.
Mounting The Amplifier
The dBM12 amplifier features four mounting tabs located at the amplifiers four corners. Choose a convenient mounting location with unobstructed airflow. Using the supplied screws
and grommets, gently mount the amplifier in to position.
DO NOT OVER TIGHTEN THE SCREWS.
