What would happen if i ran 2 plate amps to 1 subwoofer?

What would happen if I ran 2 of these plate amps into my single subwoofer? I would keep the gain levels equal at all times! I ask because these are 1000 watts each and the sub handles 2000 watts.

For the price of two of those plate amps, why wouldn't you just go with one Inuke 6000 at half the price? I do not believe those plate amps are bridgeable.

Thinking about it, just for fun, you could make it bridgable by powering the second plate amp through an isolation transformer. Then you can bridge the outputs (tie the "-" of one to the "+" of the other etc.) Just looking at Digikey's website, you're looking at a couple hundred dollars for the transformer. I guess that's why people buy the iNukes

If the plate amps have a Phase switch or knob, you can reverse the phase on one of the amps and connect the speaker across the (+) terminals of each amp.

Might not be a good idea with a woofer less than 8 ohms nominal, though, as each amp will see a load below 4 ohms.

My first thoughts reading this in the morning was that gain knobs on amps are not all the same, so while it could be done with a DVC driver you should really have a way to measure output of each so one isnt getting 50-100watts more then the other. Who knows if a 50 watt difference is enough to hurt, but id want each voice coil to receive the same power. For the price of two of those you could do better then an Inuke I think as well. Not saying the Inuke is bad, I do think crown is better though!

Not recommended, but as said before, it would work for a dual coil subwoofer with 1 plate amp running each coil.

How would you know if both plate amps are in phase with each other? If one was even slightly out of phase, you'd be missing out on some power. Or am I all wet here?
