[QUOTE="audioholic, post: 762080, member: 549629"] How did the sub blow? Smoke? Start banging? Im wondering if it was a thermal (overheating) or mechanical (suspension bottming out) problem. Either way, its likely you did not have the gains set properly. And, the fact you blew the sub one day after installing it tells me you did not take it easy on the sub to allow it to break in. People can say what they want about break in, but I wouldn't pound new subs hard till the suspension loosens up. edit: BTW just noticed, if you ran your DVC's in parallel like you say, that was a 1ohm load, not 4ohms. Your subs were getting 1000 watts, and you were running your amp under its rated impedance. That would explain the immediate failure. oops! [/QUOTE]
