The headroom is up to you to manage so I don't know exactly what you mean by saying if you can have 6dB of headroom. I'll explain... The amp has about 1dB of headroom built in, that can't be changed, the speakers have about 6dB of headroom, that can't be changed either. So, if you want 6dB of headroom you need to keep the continuous power 6dB below what the limiting factor (speakers or amps) is. I'll give you an example:

If your speakers can handle 2000W peak and your amp can give them 10000W at their rated impedance, then the speakers are the limiting factor and if you need 6dB of headroom you should keep the continuous power below 500W (2000W-6dB).

If your speakers can handle 25600W peak (4X SRX728s) and your amp can give them a peak or burst of "only" 12000W (2 ohm stereo MA12000i) at their rated impedance, now the amp is the limiting factor and if you need 6dB of headroom you should keep the continuous power below 3000W (12000W-6dB).

If you operate the system this way you will get 3dB less SPL then what you would have if you had an amp that would be able to supply all the power the speakers can handle.

I don't know which type of music you play but 6dB sound a little low.
