Big 3 Wire Upgrade

This is WTF I'm talking about.... 
Definition: the "Big Three" upgrade means improving the current capacity of three cables: 1) alternator positive to battery positive, 2) battery negative to chassis, and 3) engine ground to chassis.
I plan to replace my Bose system and add about 1000 watts for subs and 400 watts for speakers.
