Ok, so if i have 2 subs that are 500 watts RMS, then i would need a amp that runs at 1000 watts RMS, right? (that's after figuring out all the wiring and ohms, etc)

Not correct.

That is the MOST continuous wattage they can HANDLE without dying on you.

What kind of subwoofers are they? What kind of enclosure are you planning on?

agreed...you do not NEED a 1000 watt rms amplifier.

Yes, I wrote more but then just decided to go with my single word answer. posted_image

They are correct, you do not "need" exactly a 1000 watt RMS amp. That is what you would get if you wanted to fully power them. The enclosure also can dictate if you are able to feed the full 500 watt RMS a piece to your subs.

It's a sealed enclosure, they're Rockford P3's DVC, 12", 500 RMS apiece

how much power a driver handle is dependent on the enclosure...he could very well exceed the mechanical limits with 200 watts a piece
