[QUOTE="DFW40, post: 565351, member: 556468"] If I were you I'd just add two more 12W7's since you already have two. That way you do not have to worry about taking a loss on the used 12W7's. The new amps will provide 1000watts rms each and each sub will handle 750RMS. This setup will have 1000watts going to 2 subs that can handle1500 watts between the two of them and remember that depending on box size your subs could easily reach Xmax at half their rated power. I would rather run more subs at 1/2 to 3/4's of their rated rms than to run fewer or lesser subs to their max rms. You will get more out of a subs first 500 watts than the second 500 watts. Take a look at Adire's chart for power/xmax/box size. This is not the same for every speaker but it does make a good point.
