IMPORTANT: Disconnect the negative (–) battery terminal of
the accessory battery before beginning the installation.
• Always wear protective eyewear when using tools.
• Choose a safe mounting location. Check clearances on both
sides of a planned mounting surface. Be sure that screws
or wires will not puncture the vessel hull, fuel lines, or wiring
harnesses, and that wire routing will not interfere with the safe
boat operation. Use caution when drilling or cutting in the
mounting area.
• Choose a location that provides enough air circulation.
• Do not mount the amplifier with the heat sink facing downward,
as this interferes with cooling.
• Mount the amplifier so that it will not be damaged by the feet of
passengers or shifting cargo.
