whats a good 1200 watt amp

Unless you are running 6 ohm subs, how are you arriving at 2 Ohms for three subs? If they are 8 ohm, you ususally end up with 2.66 ohm (slight decrease in power for most mono 1200W amps). And if you are running three 4 ohm woofers, you end up with 1.33 Ohm which can fry many amps. If the woofers are Dual voice coil, you may want to think about a 2 channel amp.
