You had the settings set incorrectly and overdrove it. The voice coil leads are burn't open. If you look at the little flexible braids by the terminals I'll bet they are black/brown and maybe even burn't in half. It's toast.

SOURCE: Smoke coming out of subs
If smoke has come out of the subwoofer, the speaker itself, that means the voice coils have been heated excessively and they are damaged or in this case, I'd say completely blown. Voice coils blow because they've been driven too hard, too much power, too much distortion for too long.
If you can get access to the front of the subwoofer speakers, gently put even pressure with your fingers near the middle of the cone, just around the edge of the centre dust cap and push gently and slightly inwards. If you hear or feel a "scratchy" type sound or feel, or if they dont move in freely, they are blown. And if that's the case, your amp could be damaged as well.
Most modern car amps have circuit protection and will shut down when they detect a load greater than they are used to so the amp MAY be ok. One way to test the amp is to hook another speaker to it, any speaker as a test is ok, and see if sound comes out. Make sure all power is off when connecting and disconnecting speakers!

Your overdriving the Subs and burning up the voice coils. Its really not worth fixing. It almost costs the same to fix as to buy a new one. Set you Amp gain down low. Then crank up the volume with a bass test. Slowly crank up the gain until you get some distortion. Then reduce the gain slightly. You will be set then to crank it up to the distortion level and not blow you speakers. Open a can of whoopass on anyne the cranks up on your gain. It will be costing you another set of MTX's.

Happened to me, i also had a metallic/iron smell coming from my sub... i pronounced it dead. had to buy a new one and it worked fine... if you believe its not dead then your amp is not getting enough power and most likely shutting off (protection mode), you can try buying a cap, farad 2 or better will work and is suggested for larger subs anyways
