I would go at least four, if not zero. If you are only running the 400.1 you could probably do 8, but if you ever plan on upgrading, you will thank me down the road. Just warning ya, 0 is a beoch to work with though.

I've used 4 and 2 for power didn't notice a difference. I doubt you will either unless of course you were using an amp much bigger than the one you have.
As for the other guages mentioned that is what I would stick with.

Also, go to a place like Acklands or another store that supplies welding shops with their cable. This will work as your power wiring just as well as any cable you would buy at an electronics store and also goes for a much cheaper price.

It will put out the same amount of power based on the same voltage. The longer the run of wire, as well as a smaller wire causes voltage drop.
ie: at at 100 amps 5 feet of 4awg will drop .1volts
18 feet of 4awg will drop .3volts
5 feet of 8awg will drop .5 volts
18 feet of 8awg will drop 1.2 volts
now these numbers were just made up by me, but they show that at a certain current draw, there will be voltage drop. The greater the length and smaller the wire, the more voltage drop that will occur. If you get into really extreme situations, yes your wire can melt, but that is the reason that you fuse it under the hood.
