make sure there is a secure, waterproof connection on all wires.
• Check the connection between the wiring harness and the amplifier, and make sure it is
seated securely in the port.
• Check the power-wiring connections to the fuse or circuit breaker and to the battery and
repair or tighten any disconnected or loose wires.
• Check the circuit breaker and reset it if necessary.
• Make sure the supply voltage is within the specified operational range for the amplifier.
• Make sure you are using the appropriate gauge for the length of the power cable run, and
replace the cable with a thicker gauge, if needed.
