I am going to be installing a very nice upgrade to my 9000's stereo eventually, but I will not do anything before i correct one thing first. What that is, is my ground wire on the alternator. Mine is rather, well... almost worn away. My question is what gauge is the sock cable, and how long should it be? I intend to make the replacement one myself and would just rather have all said materials on hand before going at it. Saves some time at the least. Thanks for any help in advance.
