at least 8 gauge would work depending how long your running the wire. The number of subs does not matter, only the power rating of the amp does. my advise would be to just go ahead and buy a GOOD 4 gauge kit, this will give you more flexibility when you may decide to upgrade your system. don't cheap out with anything it's just a waste of money.
Well, 18 inch subs are the biggest among this moment. There are bigger subs out there over 18 inch.
That depends on the power ratings of the subs.
4 gauge

Type in google 'subwoofer wiring' and click on the 'crutchfield' link. Really good diagrams on how to connect dvc subs and svc subs to any amp.
Currently, I have 550 subs and hope for the support of community
You can go to Kicker.com for the wiring diagrams for your sub.
