16 gauge wire?

[dreamingISdrifting]

I have read numerous threads about people upgrading their cars to 18 gauge. I was wondering i you could do a 16 gauge upgrade? Or maybe even a 14 gauge upgrade. Would it fry the fets due to over-voltage? I was just wondering why no one has really used 16 or 14 gauge wire. Please do not tell me the wire is to big to be soldered on as an answer. oh and one more thing is the max capacitors you can run on your motor 3 and can you run a full size Deans plug instead of the micro??
