I have 2 woofers blown on my Lsi 15 this week on a different day. My amp is Simaudio i-5 integrated. A few minutes ago, I heard a big "pop" coming from the speakers and the light on the amp came on automatically (the amp was on standby mode,but gets very hot). I immediately shut off the amp and heard another "pop". I turned on the amp again and played some music but noticed that the woofer is making a "clicking" noise. I had the other woofer blown the other day? What is the cause? Do I have a bad amp or I have bad electricity(voltage drop???) Please help!!
