| 8 gauge will carry like 50 amps
10 gauge like 30
12 around 20
12 is more than enough for your in car speakers. if you have big bass, maybe 10 ga. for the subs. or just use real think wire and tell everyone that you've got 2 gauge going to the subs, even though you don't need it [IMG]i/expressions/face-icon-small-cool.gif[/IMG]
