yes he is right to a point.See subs don`t keep its ohms thruout the range they play some drop just a bit.So say it is rated at 4ohms(the sub) at 100Hz it may read 4ohms but at 50hz it maybe 3.6ohms and so on.So what could be happining is it is dropping just below the 1ohms enough to put the amp in to protect mode.It could be an under voltage problem as well.Less voltage means more heat and smoke to come.It could also be you are over driving the amp some have a shitty thing in them that will send an amp in to protect at a set voltage draw or voltage output.

Truth is it can be a ton of things and if the dealer know what he is talking about he should have said this and not try to just say scrap it(ya so you can buy from him now right)
