Reverse left and right speaker leads to determine if it is occurring before the speaker
Speaker is distorting at high volume levels
Check speaker load impedance capabilities for the amplifier
Verify that amplifier and/or crossover settings are correct
Confirm that the speaker load impedance recommendations are followed. Check the wiring configuration of the speakers.
(To verify proper load impedance, use an OHM meter to measure the total load for each channel of the amplifier.
