Multiple Subs?

Basically, heat makes the voice coil's impedance increase. Higher impedance means less output from the amplifier. In other words, you do not gain the same amount of increase in output going from 1,000 watts to 1,001 watts as you would going from 1 watt to 2 watts. Heat decreases efficiency, basically.
So... having more motors to spread the heal throughout means more surface area on voice coils to dissipate this heat, meaning less impedance rise and greater efficiency of your watts.

The 1 to 2 vs. 1000 to 1001 watt is a terrible example. 1 watt to 2 is doubling power and is theoretically a 3dB gain. 1000 watts to 1001 is a tiny tiny percentage with an impercepible dB gain, really nothing to do with power compression here.

Then give us your example of power compression at work.

Im still a freshman in audio...in other words are you saying be careful on going 4 12s? Go the 15s? Really not understanding.

No, Im not saying that.

Double the power from 1000 to 2000 and you likely won't get as big of a dB increase as the 1 to 2, or 100 to 200 due to the heat.

4 Type Argh's on 3 to 4k will do good

He is saying what I said.

It is better to spread the power over more coils.

1500w total on 4 12s would be better than 1500w total on 2 15s.

sorry guys still not understanding this part? Yall went into some technical stuff.

Oh okay i gotcha...

Would you guys suggest running the R's at 2 or 1 ohm?
