my friend has a bxi2006d. 4 gauge power and ground fused at 80 amps. hooked up at 1 ohm. it was turned down and it made a pop noise and smoke came out of it. the thing is the amp still works.

what could this be?

By it still works do u mean it still turns on? Cuse just cuse it turns on doesnt mean it works.

i had a lanzar vibe that did that and kept playing for about another half hour and then let more smoke out and quit. had to send it back to get a refurb

in the power distribution industry this concept isn't uncommon. the breakers on large generators are set to allow the generator to provide at least 300% rated current out, that way if something breaks down the line the generator can just pump out current and either fry something into submission, or trip a breaker that is closer to the fault.

similar things can happen. especially if a redundent component explodes, removing it from the circuit.

still, redundency isn't usually built in, and the rating is reduced.

some components are designed to be self healing where damage will just fry off the offending section and leave the system in a working condition.

LOL. Okay....

What probably happened is a single FET on the power supply or output went bad, and the other FETs where strong enough to burn the the leg(s) off of the offending FET, therefore everything goes back to normal, except at reduced capactity.

While this is rarely the case, it can and does happen. Good luck with it, you are now making the remaining FETs work extra hard to keep up. Soon you will have more Magic Smoke.

ive had a n mtx 1501d in he past smoke and keep playing... turned out to be a rectifier on the board. played fine and ddnt have any noticable drop in performance. eventually it got repaired when the amp took a drop to the floor on accident (it didnt like it very much)....

crazy when that shit happens......
