It depends on the amps... Some amps need 0ga others are fine with 8ga.

Depends on what current you are drawing through it...

What amp?

I have an 1100wrms amp with 0 gauge inputs and run 95mm 00 gauge cable to it for minimal volt drop... however that is a bit overkill =)

For a 600wrms and above amp I would recommend you run 2 gauge cable. Anything less should be alright with 4 gauge.

...but yea what amp?

4 gauge is like 25mm or thereabouts
2 gauge about 35mm

Just buy car audio wiring and then you won't need to know the metric size.
