Yes, you basically upgrade the current stock wiring in thoose locations. You dont have to remove the old stuff just add another larger wire run. Most people would be fine with a 4awg Big 3 upgrade. Some people choose to do 0awg, but im not convinced that large of wire is completely neccesary for most systems.

If you check out www.edesignaudio.com they have some Big 3 kits. They are slightly more than pieceing together all the wire and connectors yourself, but this way you know everything is included.
