will there be a big difference?

I have a kicker zx750.1 amp to use. At 2 ohms I have 925rms and at 4 ohms I should have around 450-475rms. Will be installed in a regular cab truck with a small sealed box of 1^ft max. My question is will 1 10" sub off 925rms be a lot louder than 1 10" sub off 450? I know its double the power but with the application it will be used in it's hardly the ideal application. I have been looking at the fi car audio ssd10 off 925. With the 450rms I have been looking at the AA arsenal 10" off the 450. Will there be a large noticeable difference in these two setups?
