Help! Did I blow the subwoofer?

[gochal]

Heard a very quick, loud boom that shook the floor while hooking up the powered subwoofer to the receiver, and now it doesn't work at all. No burning smell, and no cracks in the cone. Checked the fuse, and it looks fine. Shouldn't I have expected to smell something burning if I blew either the subwoofer or the amp in the subwoofer?

Not if it died from overexcursion. Does the cone seem okay? Press on it gentally in and out and see if it binds. The suspension should be stiff but even, and not bind at all through its path.

Does the amp on the back light up?

Is it connected to the correct input?

You can pull the driver out and test it out of the box. That way if it works you know it is the amp and if it doesn't it's the driver. Assuming all is connected correctly.

The simple answer is that if it still works, no, you didn't blow it. You got lucky.

If nothing else you learned why everyone says to make sure all your equipment is powered down when kerfutzing with the wiring.

You don't go playing with the wiring under the cars hood when it's running either.

You won't smell anything if it happens instantaneously unless you cause a short circuit. Making connections while equipment is on is the easiest way to damage it.
