How many ft. of wire is needed? How many terminals are needed for a b-series? What gauge wire?

Thanks

 

Just look under the hood and measure each wire individually . I went to the local audio shop and had them make me 2 out of 4ga speaker wire with the terminals for $7

 

To do the whole ground upgrade right, you need about 15 feet. Use either 4awg or 8awg.
There are five major ground points to connect.
Tie them all back to one common point for the best results...

 

Yup, upgrading the factory grounds are pretty much a necessity IMO...
The factory body has a lot of seams, welds, paint, sealant as well though.
You will see better results with more cabling and bringing it all back to one connection...
