Big 3 Wire Upgrade
All, have you done the big 3 upgrade yet? If so, how did you deal with the fuse block / terminal block that is at the battery?
Also, where is the chassis ground located at?

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.

Hey, I didn't name it. 
In talking with several installers and reading online, it is a good audio / electrical upgrade to do if you are adding in amps.
