Corvette Big 3 Upgrade
I've been into car audio for a long time now and have done this wiring upgrade to all my other vehicles. For those that aren't familiar with it here's a link to an explanation.

Basically, it adds large guage wire to take over for the often too small factory junk. As these cars are sooooo power hungry I figured it was a no brainer. So far just idling in my garage I have already noticed a .4-5 increase. The weather sucks outside so I couldn't take it for a spin but I'm happy. Here's a few pix for you guys.
Here's the wire size diff. The far left is the factory, next is the 4 guage, then the 0/1 guage.
This is how it looked before :
And after:
So in the above pic, the two 0/1 grounds (black) go to the chassis ground right below the battery tray, and to the supercharger bracket. The red 0/1 goes to the alternator, and the red 4 guage goes to the fuse box.

Alt staight to the batt +. I also did a 4 guage from the batt + to the underhood fuse box. Sorry about the pix not showing up, I moved them around in my photobucket account.
Here you go:
I can get more if you want them.
