Hey guys, I just bought some new JBL Spot speakers the other day but when I plugged them in I heard a "pop...pop...pop...pop...pop" noise coming from the speakers. I have tried to plug them into different ports but to no avail. Any ideas I would like to not have to take them back. By the way I cannot listen to music or hear volume with the popping going on. Thanks for all help in advance. Also the green LED that is supposed to be on is flashing green instead of staying flat green.
