Ok my sub is 1200 watt, any amount of watts the amp should be?

You should be matching your amp (rms value) to your sub (rms value). Most models of both items should give you a value for this. So for a 400watt rms sub you should have an amp that amplifies up to that range. If you go a little bit under ( a few volts) it wont make a very big difference, go heaps under and you wont get the sound your sub 'could' be putting out. If you go higher you run the risk of destroying the sub. Hope that helps.

It's actually better to buy an amplifier that makes a little more power than the subwoofer is rated to as it's harder to hear a distorting amplifier (clipping) than a distorting subwoofer (bottoming out).

Not entirely true, under powering a speaker can be more dangerous than over powering one. If you drive a 500 watt sub with 250 watt and push the amp into dc and clip you will take out the voice coil alot faster than running a 550-600 watt amp. DC/Clip is far more dangerous than over excursion.

if its a single 4ohm coil, I'd get a bigger 2 channel amp to run it, something like the ReSponse 2x150watt from Jaycar.

Otherwise, to get a good amount of power into a single 4ohm sub will require a monoblock that does something like 2000watts at 1ohm.

280 sounds like the combined handling left and right, 140rms either side from memory. So if you've been reading then a 4ch amp that offers a bit of headroom above that. Do you want me to link you to an amp that cost's $2500? It will do the job, otherwise if not, you need to be more specific about what you want to spend.
