No problem at all. I have an amp capable of over 3000 Watts on the bench at 13.8V ($1500 Mmats USA goodness baby). I've used that amp on everything from 300W testers to 4000Watt-capable Phoenix Gold Titanium Elites.
A subwoofer's power-handling is never "literal". It depends on many factors. Seriously. If you have it in a big breathing ported enclosure, even with your subsonic filter, your sub can only handle so much excursion before it smokes on mechanical limits. In an enclosure with more resistance to over-extension, the driver will have better power-handling, and this includes harmonic resistance, not just presure.
I've had 300 Watt woofs running daily on 450 Watts of absolute true RMS measured power and never a problem. I've also seen and myself smoked 800 Watt "rated" woofs on 100 Watts.
Short answer: yep, if done right, by someone who knows what the hell they're doing, you're absolutely fine.
In fact, most popular consumer amp's with a rating of "1200 Watts RMS" won't even be putting out a KW on car power.
* edit... I should add... it's absolutely possible to exceed thermal and mechanical limits of a sub (over-power it), so in no way am I saying that putting 2000 watts on a subwoofer designed for 400 watts is ok, even if installed well. What I'm saying is that you can "tune-down" a super-powerful amp to meet the requirements/capabilities of your woofer in its given enclosure and frequency range. But I reiterate that a subwoofer rated at 500 Watts (for example), may very well be able to handle 800+ watts on a daily basis if there is no clipping/distortion, good crossover setup, and dependent on the enclosure.
Cheerio,

I wish you had provided me with the actual model number of your Subwoofer and the model number of the amplifier.
You must keep in mind that the numbers posted on boxes are highly misleading - they are marketing gimmicks.
Sometimes a company will post the total output of a amplifier rather than post the power output in different setup situations.
If your Subwoofer recommends 1000 WATTS RMS @ 2ohms (with a max power of 1300 or higher) and your amplifier claims to output 1200 WATTS RMS @2ohms then you have no problem at all. However, be certain that this is the case.
You wouldn't want to have a woofer that has a MAX POWER of 1000 Watts matched with an Amplifier that outputs 1200 watts because you will more than likely blow the subwoofer out.
When you ask questions, tell us...
Subwoofer's max power
Subwoofer's OHM amount
The number of Subwoofers in your setup
The Amplifier model #
The amplifier's output at ___Ohms
and the resistance you are wiring your system to
Keep in mind that some amplifiers are not stable at certain OHMS. Allways check the box to find out how stable the amplifier is and at what resistance.

Once again HiAmp puts game to the noobs, there is no such thing as underpowering a sub and Amps dont kill speakers, People with amps kill speakers. Your amp only puts out what you tell it to(assumeing its not underated) so you can have a 10giga watt amp if you dont turn it up over the speakers rateing you cant really tell the diffrence between the 10gig and the 1000 watt amp becuase the speakers gonna be playing off of 1000 watts regardless

It will be ok once you set the gains correctly and here's how...
You have to know one thing before you set the gain (or level) control. You must research and find out what the maximum Volts RMS can come from your HU.
Just for an example, we'll say 5 VRMS. The gain will need to be set for about 7 VRMS to compensate for the difference in output wattage.
So whatever the MAX VRMS is from your HU, add about 2 or 3 for the gain control.

no dont do it teh impedence over excceds the impedence on the amp there for if you send a watts pulse to the woofer u will blow ur fuses inside and out side of the amp i high suggest not to do it

as long as the speaker doesn't have more watts than the amp
your good to go!

don't turn it up or you won't have a subwoof any more. 50% over rate speakers and they don't blow!
