I have a Kicker zx550.3 that has a issue. The light on the top is flashing red and green and i have no sound. It went from working and then it just quit. What is wrong with it, Reading the manual it tell if it is solid red or green But it said nothing about if they are alternating red green. I was hoping it was just the hot Vegas weather that i am in currently. My normal Washington rainy weather seldom hits 85 let alone 100 here in Vegas. any help would be appreciated.
