How to Reset a Fusion® Marine Amplifier
When a Fusion® amplifier powers on with a red light, it has entered protection mode and must be reset and tested again. Before resetting, it is important that all other installation specifications are met including wire gauge, wire length, and fuse capacity. See the Owner's Manual for more information on installation specifications.
Resetting the amplifier
- Turn off all power going to the amplifier, including batteries and stereo
- Remove all wires from the amplifier including power, ground, remote on, RCA connectors, and speaker wire
- Some batteries and switches will prevent any power from transmitting at all when turned off. This is not sufficient. The amplifier must be physically disconnected from the battery and all other wires
- Leave the amplifier disconnected from all wires and cables for 10 minutes
- Reconnect only the power, ground, and remote on wires to the amplifier
- Turn the battery back on
- Turn the stereo on
If the amplifier powers on with a green light then the RCA connectors, speaker wires, and speaker terminals will need to be tested for any grounds or shorts to determine what caused it to enter protection mode. If the amplifier still powers on with a red light, obtain the model number, serial number, and original proof of purchase and contact Product Support.
Note: Regardless of whether the amplifier displays a green LED after the reset, resistance on the speakers must be tested at the speaker terminals before reconnecting them. If resistance is lower than what the speaker should be, the speaker is damaged and must be replaced. Failure to test resistance or to replace a speaker with with lowered resistance could result in damage to a connected amplifier or stereo.
