I noticed a few posts in various places asking about the big3 so I found a post on sound domain that was pretty helpfull

http://forum.sounddomain.com/ubbthre...e/1#Post312025

but after reading through it all I have to mention that he incorrectly stated that the power cable from the alternator to battery should be fused to the capacitance of the cable, that is wrong. You must use a cable of large enough gauge for the power/load flowing through it, meaning; for example, 2k-01 max alt is 100 amps and 02-03 max alt is 110 amps, 4 gauge cable is rated to 140 amps (if I remember correctly, feel free to correct me if I'm wrong) so it would be the wire of choice but 2 or 0 gauge cable would do just fine because there rated for even higher amperage but lower gauge cable would not do because they are rated below the alternators amperage, understanding that - your alternators amperage (or in most cases - the load) is what dictates the size cable because of its amperage, the same would hold true to the fuse on the line. The 2 or 0 gauge will not increase amperage on the line, it may increase the ease of flow of current??? maybe, but the current/load flowing through remains the same. I know alot of people will disagree - many other posts and other sites still argue this point - but I do know this as fact. At any time anybody can speak to an electrician to verify this.

I just wanted to share this
