How much current (Amperes) the system needs depends on the amplifier you use. For 1000 watts generally you'll need a 100 amp alternator or so.

Wire gage is also dependant on how much current is drawn. More amps needs thicker wire. For 2 reasons: safety and voltage loss. Wire too thin gets hot, melts insulation, shorts out, makes fires. Thin wire also has more voltage loss, so the amplifier doesn't get the input power it needs and can't make full output power. It all works together.

I have no clue about Hondas, can't answer that.
