whats the make/model?
I don't care if that fact is true or not. It's the application of that type of power...it has no place. If it's cheap...good on you, nice find. It just doesn't seem like you're approaching this the right way. Your "300 watt" amp was probably setup incorrectly. That's why it's over heating.
Here: dB-SPL chart - Amplifier Power and Sensitivity
Apply the rule of thumb, double the power and increase 3db. Now what happens at 4000w? You've increased your sound by approximately 10.8 decibels at a listening distance of 1 meter.
But what about anything past 1 meter? You lose output. A sensitivity of 87 decibels is typical of car subwoofers these days. Assuming your speaker has the mechanical ability to use 4000 watts "rms"(that's a bull**** rating that doesn't make ANY sense. Only car audio uses RMS)....then you're talking ~120decibels of output at just 1 meter/3.28 feet. I wll say that this scratch paper information doesn't take into account cabin gain...But it also doesn't take into account the specs of the speaker either. So you'd probably damage the speaker before anything good happened.
So how do those guys hit 150+ decibels? How do they do it with 500 watts? Design. If all you're doing is throwing "watts" at your speaker for output you're going to destroy something. That's your problem with the current 300 watt amp. How did that one guy get 150+ decibels out of a 6.5" subwoofer? A very nice installation...6th order bandpass?...maybe. Anyways, I'm not mad at you. I just want you to think a little bit more about how you're going about this before you really screw something up. You'll end up confused and mad in the end with your current pathos.

Tell all of that to thylantyr...
Builds a line array THEN proceeds to power it with +1000 W per channel.
