Yah the quick and dirty equation is V=(SQR)(P*R)

    Ever wonder where that 2.8xx VRMS @ 1 meter comes from.  Its supposed to represent 1 W at 1 meter @ 8ohms but a lot of companies try to spec a lower Z driver with the same voltage level to try and pass it off as being more efficient.

Ivan: very true, for 8 ohms at 800w you're only getting 80volts (instead of 88 volts from 1000w at 8 ).  Do you know of a plate amp that would be better match the Lab sub, offering 1000w into 8 ohms..?!

This should about do it : 2000W into 4 ohms
