What is happening is that your amp can deliver 1500 Watts at a given impedance. The Sub PROBABLY is a higher impedance. Your amp runs out of voltage due to the speaker impedance, hence it "flat tops" or clips.
You will probably find the sub is 8 ohms and your amp might deliver 1500 Watts on a 2 ohm system (this is "specsmanship" to sell their product... more is better thing...
If your amp was as above, the max voltage output would be the same before clipping but with the resistance 4 times, the current is only one fourth that which would deliver 1500 Watts. So you would only get 1500/4 Watts into the speaker or about 375 Watts.
