Heres a few different wire size guides..

This is one from the 12volt source.. it is WAY OFF, but take it with some salt:

(says 100 watts rms is 16 amps!... 16a x 12v = 192watt, so that means your device is 50% effecient?!? )

ALWAYS use larger wire than needed. This will minimize wire temperature (help reduce risk of fire), minimize the voltage lost (if maxing out 8 gauge you may have 12.3v at the end of the wire with the engine running, and by only replacing it with 4 gauge can go up to 13+v).. (more volts = more power from your amps!)
