Wow! Big Three works

So I finally did the big three on my 98 Honda Civic DX....and WOW, what a difference.

My Alpine MRV-F345 voltage display was reading about 12v with front 6.5" comps and rear 6x9's only (no mono block)

Now it's reading 14-14.4v....time to hook up my new MRP-M650 and see how far it dips under load.

I did this to my 91 corolla that we are building and went from 13.9-14.1 at idle to 14.52 steady after the big 3.

I used a double run of 4ga from the neg battery post to the chassis, double runs of 4ga from the chassis to the engine block and 2ga from the alt to battery.
