Precautions
Mounting: Do not operate the amplier when it is unmounted. Securely attach
all audio system components within the vehicle to prevent damage, especially
in case of an accident.
Wiring Protection: Ensure the wire connections are protected, not pinched,
and not likely to be damaged by nearby objects.
Battery Disconnection: Before making or breaking power connections,
disconnect the vehicle battery. Make sure your head unit or other equipment is
turned o while connecting the input jacks and speaker terminals.
Fuse Replacement: If you need to replace the power fuse, only use a fuse
identical to the one supplied with the amplier. Using a dierent type or rating
may result in damage that isn’t covered under the manufacturer's warranty.
Protection Circuitry
The built-in protection circuitry in the Marine ampliers will disable the
amplier if it detects:
• Input overload
• Speaker short circuit
• Extreme temperature conditions
Protection LED:
When the protection circuit is activated, the Protection LED will illuminate.
Steps to Follow:
• Thermal Overload: If the shutdown is due to thermal overload, allow the
amplier to cool down before restarting.
• Input Overload/Speaker Short Circuit: If the shutdown is due to input
overload or a speaker short circuit, correct the issue before restarting.
• Restarting: Turn the remote power OFF and then ON again to restart the
amplier.
