I have an old 8" bazooka sub just sitting around and I want to kill it. I think it is rated at 50w rms. I figured I'll run about 300w rms to it in free air and play a 60hz sine wave.

Is there a better way to make this thing smoke besides lighting it on fire?

I know it's pointless, but I figured it would be cheap amusement.

Do a search for author "uthinkuknoaudio". He used to get really, really excited about things like that, and there are several threads to demonstrate it. Here's one!

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

You can't, subs aren't alive.

That won't do it - insuffucient voltage. Welders are high CURRENT devices, where their output voltage is very low - usually 30 volts or less, and most are DC output as well.

(Vp-p)^2/Load

30*30/4

900/4=225 watts - (depending on the welder - my welder happens to only be 17v, so it WOULDN'T kill it...)

I re-read the original post, and in this case, yes, a 50 watt woofer WOULD go away, but it'd me FAR more spectacular plugged directly into the wall...

170*170=28900

28900/4=7225 watts!

Oh, yeah. That'd "git 'er done" in about 10 cycles!

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

You know that kid that drives that beat up honda down the road that has the primer grey body kit and the really bubbled window tint?

sell it to him, he should blow it up in the most entertaining way.

I hate questions like this.

OK, why burn it up? Sell it for $20 and go buy yourself a tootsie pop.
