Crazy question. Any upgraded 2 prong 18 gauge power cords available ?

This is for a Bose 700 soundbar and 500 wireless sub. Just for a out door kitchen/bar.  The power cords are just 18 gauge 2 prong. Does anybody make a thicker gauge in a  IEC C7 configuration?.   It just seems the stock cords look they belong on a clock radio. Probably may not make any difference in SQ but it could. :)

Thanks,

Russ
