What gauge of wire should i use??

[Shank265]

I have 2 10" kenwood db+ with the polkaudio c500.1 monoblock and i was wondering what gauge wire i should use. i currently have 10 gauge but i was also thinking about putting a capacitor in it. If i put in like a 8 gauge would that be good or should i go bigger? And if so do i need a new altinator for my car because i think it is stock.
