Sub RMS to Amp RMS Question

I have a 450w rms American Bass 10" dvc 2 ohm sub I just bought. I also have a 750w rms at 1ohm, 565w rms at 2 ohms and 340w rms at 4ohms amplifier (dynamic over 1k at 14.7v at 1 ohm.) I know gain doesn't control the amp power so I am a little confused on how to wire it. Should I go series for a 4 ohm load on the sub, or send it parallel for a 1 ohm load? I don't want to blow the sub. Been out of the game for a very long time (late 90s) and a lot has changed. Thanks in advance.

I currently have an 8k on a 2500 watt sub albeit a very conservatively rated sub but impedance rise is real bruh

Awesome! Just the help I was looking for. I was leaning toward the 1 ohm load and taking down the gain, should run really clean. Thanks for the help and the links.

Thanks for the help guys. Got my new amp set to 21v +-0.1 and the sub is performing great. Thanks again
