So 1200 watts to each 1400 watt peak power square sub of the same brand.
If your total system power is more than 1000 watts RMS you will need to:
1. Upgrade the alternator to a high output alternator
2. Upgrade to a heavy duty deep cycle battery
3. Upgrade the "Big 3" - that is to replace the power wire between the battery and alternator and the ground strap.
Failure to do this will result in you replacing them anyway as the alternator will eventually fail.
Here is a guide that will calculate what size alternator and power wires you need http://www.datafilehost.com/download.php...
You'll need Microsft Excel to use it.

The watt rating on subs and amps (especially cheap ones) is usually bullshit. Especially if it says "peak." You want to look at continous ratings. There are many subs rated at 1000+ watts that will run fine on 100 watts clean power. Conversely there are subs rated at 150-300 watts that will be underpowered on an amp that "says" 2000 watts.
Generally higher quality gear doesn't make outrageous claims in their ratings. Some amps that cost thousands will be rated at 50x2 watts the key point being that they are 1/4 ohm stable and will be 800x2 @ 1/4 ohm.
Have a look at xtant amps: http://www.xtant.com - very expensive very high quality amplifiers. The power ratings are not outrageous. Chances are any one of them will destroy your "2400 watt amp." If you really did have 2400 watts of clean real power in your car your ear drums would probably explode anyway. Don't be fooled by bullshit ratings.
