You will want to match the RMS watts between subs and amp as well as impedances.
If your subs are 500 watts RMS @ 4 ohms each, you can either:
Get an amp that is 1000 watts RMS X 1 @ 2 ohm and wire the subs in parallel.
-or-
Get an amp that is 500 watts RMS X 2 @ 4 ohm and wire each sub to each channel.
Just remember, the harder you drive an amp (lower the ohms) the hotter it gets and the easier it is to introduce distortion.
Oh, and DO NOT adjust your gains as someone else suggested. The gains MUST match (or be a little higher than) the volts RMS of the HU to prevent clipping. Clipping is what happens when the the coil smacks the bottom of the magnet well due to the amp providing a square wave instead of a sine wave.

make sure you base your amp on RMS output, and not TOTAL output. now your subs should have a rating of recommended amp watts, well it IS their subs, they know what they're talking about. choose an amp as close to the higher end of the spectrum as you can afford. more power is better quality and more noise. hooray.
so let's say you have 2 1000 watt subs, and i'm guessing that's max, so they're probably 400 or 500 watts RMS, am I right? so with this you'll need probably a MINIMUM of 200 watts per speaker. but trust me, you want bigger. under powering your subs by THAT MUCH is silly. now in my personal opinion, you don't want to OVER power your subs too much, as well. it's too easy to keep turning up the gain control, pushing the envelope until the subs push back and you lose your subs in a blast of smoke. trust me, it smells terrible.
ok, well get past that whole bit about my opinion of amp choosing, and you get to the meat and potatoes.
you want 400 - 500 watts per sub, so go with an amp that has a rating of 800 - 1000 watts at 4 ohms.
this can get pricey, expect to spend upwards of 800 bucks at least.
hey, just my opinion and 2 cents, good luck with your new subs and enjoy. make sure to also hide everything. no need to advertise to stereo jackers.

IF its 1000 watts rms, then your going to need a 2000 watt rms amp.

Get an amp that can power the RMS rating of your sub. If the rms is 500 for each then get one that powers 500x2 at 4 ohms. Or you can get two seperate amps.

I gotta 1200Watt amp connected with 2 1000W 15" extremes and they sound great!!! Get an amp w/built in crossovers

1000watts is okay. I think a a 800 watts is fine also.

depends if the subs are rated at 1000RMS or 1000W peak. If they are peak then only 500RMS to the subs, if they say 1000RMS for the subs then give it 1000RMS with the amp
