Removing the Unit
To remove the commander, remove bracket mount or remove trim ring and
mounting screws, then slide wired commander out of the mounting hole.
Tuner / Amplifier Module Mounting
1. Choose a mounting area for the tuner/amplifier module that will provide
plenty of ventilation to prevent the amplifier from overheating. The
tuner/amplifier module can be mounted in the horizontal or vertical position.
Please note that when mounting in vertical position, do not mount with the
harness exit points facing straight up, as water can collect around the
chassis in these areas.
2. Using the shortest length of the recommended size screws possible, mount
the tuner/ amplifier as detailed in the diagram to the right.
3. Route the tuner/amplifier harness and cable throughout the vessel as
required. Keep some slack in the harness/cables so it won't be too tight, as
this can cause damage to the wires.
4. Follow the wiring diagram carefully and make certain all connections are
secure with insulated crimp connectors to ensure proper operation.
5. After completing the wiring connections, reconnect the negative terminal on
the battery and turn the unit on to confirm operation (vessel accessory switch
must be on). If the unit does not operate, disconnect battery, recheck all
wiring and refer to the trouble-shooting guide located in the back of the
manual.
