A. If you ask me and a lot of people DON'T get nology wires... There is a lot of contradicting info though...
Good... sort of
BAD
Do some research search google about them you'll find lots of negative comments...
B. Grounding kits are not worth buying... I guess for sake of ease it's good but it's just wire... go to a stereo shop and buy good quality wire...
C. The reason for the silver just fyi is it supposedly relfects heat better than any other color... and it's generally a high temp paint used...
