The Wistles Go WOOOOOO!
whats the VC config, how was it wired before, and how it is wired now?
also, any other changes besides amp (and maybe wiring config)?

NO changes at all.
Subs (2 12" rl-ps) wired to show a 4 ohm load.....had the tantrum in, lost output, took the tantrum out, put the orion in, with the rear channels bridged, so it should do the rated 200 at 4 ohm bridged. I only did it to verify that it was an amp problem, but it still sounds good, so I left it in.
Just trying to figure out what was going on.

No.
Pretty sure thats not it.

are tantrums regulated for 1-4ohms?
how much power should you have been getting at 4 ohms?

2-4 ohms.......should have been getting 1400+
Another thing Im thinking.....if something in the power output is what died (I think it is, the power light comes on, and the fan, theres just no output) maybe it wasnt working right before it died?

A couple of possibilities:
1) You weren't using as much power as you thought that you were. Seriously, with music you are not going to be getting much more than 30% of the max RMS output of the amp. RMS is based on a 0 dB sine wave and music is neither a pure sine wave or 0 dB. Just because you have an amp capable of putting out 1400W doesn't mean that it ever will produc that much power with music.
2) Power compression. With more power applied the coil heats up and the impedance goes up with it. The result is your amp puts out less power.
3) Output has decreased but you haven't metered it either was and you don't have an unbiased frame of reference as to how loud it was before and after the amp swap. The human ear is a terrible guage of loudness and making an A/B comparison with any time in between is not going to tell you anything if your only metric is how loud it sounds to your ear.

You're clipping the subs. You can't expect to hear distortion out of subs based on setting gains by ear.
btw, the reason they're just as loud is because they're getting more than 200 watts... and at a very high distortion rate.

I would consider that a possibility aswell, in addition to those pointed out by helotaxi
