It would be ok, but in reality you are 400 watts rms short of the rms of that sub. I think that it would work though, considering you have 2 of them. That is going to be frickin loud!
naw, he's cool. that 1600 watt thing is just a thermal rating. i.e., the point at which your VC will fry. 1200 watts is actually optimal for that sub. with my brahmas, i could either push 400watts/sub or 1600watts/sub, and they have the same 1600w rms. the techs at adire were doing backflips to get me to run 400watts/sub (i'm not into underpowering subs either, LOL). 800-1200 watts would do very nicely.
this is the exact reason that adire changed the rms of their subs, brahmas in particular. it's a great bragging right, but pretty impractical. here is the low down as per Adire, founder of the XBL2 tech in XXX: "Power Handling Power handling of Brahma is rated at 1600W continuous, 4800W peak. This was rated with the IEC 268-5 ratings method, which uses a band-limited test signal with a 6 dB crest factor. The subwoofer is powered with a signal meeting the IEC 268-5 criteria for 2 hours, with less than 3 dB of compression measured over that duration. The 1600W rating is NOT a steady-state sine wave rating! Note that the power handling is a THERMAL power handling rating! It is NOT a guarantee, guideline, or recommendation on the amount of power actually needed or that can be mechanically handled in a given box. The actual power required depends upon the application, and the mechanical power handling is heavily dependent upon the box used. When in doubt, it's best to err on the low side. Overpowering drivers is the surest way to kill them!"
exactly. man, the number of blown subs to which they have turned down warranties is in the plenty. again, they have marked down that rms significantly to 600w rms. to adire's defense though, they did provide a schematic for rms per box volume. a 1cu ft box required 800watts to effect xmax. but, yeah, i'm glad they changed the rms rating, even though now they are significantly underated, lol.
