That must have been the same thing that happened to my Opus 90w. There was a small stream of smoke, but I pulled power before anything cooked like that. MP3Car.com was very kind and quick with replacement! Kudos mp3car!
so from that thread choyak posted.. it basically says you overload you 12 volts supply and that you have to cool it better to get over 2.5Amps. dont ask me how to do it.. i dont own an opus. but thats what it say in the other thread.
just forgot to say. if the power supply like $200 and it doesnt come with fan? i dont see how the power supply run without the fan.there is notting that will give it cool. because power supply in the car in summer is going to stay hot.
