Tuner/Amplifier Mounting
1. Choose a mounting area for the tuner/amp module that will provide plenty of ventilation to
prevent the amplifier from overheating. The tuner/amp module can be mounted in the hor-
izontal 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. Attach the 4 rubber mounting feet, provided, to the bottom of the tuner/amp metal plate.
This will provide clearance from surface moisture and promote good ventilation for the
heat sink.
3. Using the shortest length of the recommended size screws possible, mount the tuner/
amplifier as detailed in the diagram on the right.
4. 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.
5. Follow the wiring diagram carefully and make certain all connections are secure and
insulated with crimp connectors or electrical tape to ensure proper operation.
6. 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.
Reconnect Battery
When wiring is complete, reconnect the battery negative terminal.
