I scoped it with a load.
And see, I hear stories like that all the time, the only thing I can think of, that might've helped them get as hot as they got, is that the motors were in the sealed chambers of my 4th order. And well DD doesn't recommend running their woofers in a sealed enclosure. And if the amps did start clipping when the voltage dropped, and the coils started getting hot, and then having no port to move some air through to pull fresh air in, all they did was move around in hot air. Plus I couldn't smell them when the motors were sealed up so no telling how long I played them while they were hot before the first one let go.
I'm debating on getting recones, and running them inveted in the box, and seeing how they hold up then, and I'll make sure to be super easy on them for a week or 2, I wasn't hammering on them (not even close) and being very conscious of DD's recommended break in time. But I couldn't help myself, I let it eat a few times.
Right now I'm looking on some input on what others think I should do, the inverted thing seems like it would work if I keep the volume down until I get an alt to keep up with the current draw.
