Hi. Last night we was having a "flat party" and I turned my Z5500 up, was quite a bassy tune, the thing is, I started to smell smoke from the sub, now I got worried and turned it down for a while, then I turned it up, just not as loud, still pretty loud though, but it was running fine. So my question is, where on earth did this smoke come from? Could it be the sub? And what damage may have happened? Thanks Will.
