Ok, so this is my first post on here. I was at band practice tonight, and in our last song we were playing, i lost sound. My guitarist said he saw a flash from behind the 15" speaker and smoke came from it. It is a Carvin Cyclops cabinet. It has a 15", 2 -8" and a horn. I'm using a Behringer 180 watt head. My drummer didn't have a screwdriver at his place, so we didn't get to investigate, and i wasn't going to haul that up to my third floor apartment tonight. Anyway, the cabinet has 2 inputs, a high and low frequency, both 4 ohm. But my head only had one output. I was never able to find a cable that split 1 mono into 2 monos, so my drummer made one. We think that might be the culprit. Since it completely lost sound, would it be more likely to be a wiring issue, or a speaker issue? Thank you in advance for any advice
