Big 3 or Big 4
Hello everyone!
I'm going to run my BIG 3. I've read article https://soundrating.com/big-three-upgrade/
1. Battery positive to alternator positive
2. Battery negative to chassis
3. Battery negative to alternator / engine ground
Should I run wire from engine / alternator ground to chassis for BIG 4? My car is 03 Monte Carlo.

I wouldnt bother. You're already running a large gauge ground from the battery to both the chassis and engine. So connecting the chassis and engine separately is redundant as they'll already be hooked together with extremely low resistance wire from your 2 other upgrades. There shouldn't be any possibility for notable differential between them if the big 3 is done right.
