Not saying it can't happen. Brazilian amps have their issues no doubt. I had a stetsom 3K3 I sold recently and it never gave me any issues at allI ran the stetsom kd models and a sd 8000 with no issues but these new lines are made very cheap. I've seen a new stetsom evo blow for no reason twice ,both times new amps also have seen many sd amps blow for no reason
