Its not a "best" situation when it comes to wiring set ups. The ohm load of the amp is based on the subs they are powering. So whatever subs you end up with will determine what wiring set up you use. The sub that you are getting will only allow you to run it at "4ohms" (that is if it is a single 4 ohm sub). If you got another one, you can run the amp at 2 ohms.

I'm getting a 4ohm dual voice coil sub, I thought you can wire it to either 4ohms or 1ohm. With the 2ohm sub I used to have, I was able to wire it to 2ohm and 8ohm. So if I wire it to 4  ohms and the sub says it can handle 600 watts rms at 4 ohms, can I turn my amp all the way up if the amp powers 4 ohms at 450 watts rms? Or should just I set it up at 1 ohm to push 1000 watts peak?
