Hmmm.  Just for reference...  By normal audio this is only 4.2 watts, 
i.e. 0.5 amps * 12 volts * .707 rms factor.  By home audio standards, 
this isn't much at all, especially for a subwoofer.  High-end audio 
systems and live concert sound reinforcement systems use very thick 
speaker wire.  But "car audio speaker wire" might mean something 
quite a bit smaller.
