Posted October 1, 200915 yr Hey guys.Today I noticed a strange noise coming from the back of my Yukon. It sounded like digital fart through the woofers. So I decided to shut it down and go check things out.The first thing I noticed was that my ground wire was basically melting at the ground point. The sleeve for the ring terminal was melted along with about an inch of wire has turned the casing form clear gray to black.I have 4ga currently for the power run, amps, and ground, but plan to upgrade soon as the rest of my parts show up. There could be more wrong, but I am at work and this is the first thing I noticed.What has caused this? Was I just pulling too much current for 4ga or is it a bad ground? My voltage has been pretty good so I was stalling until it cooled down to upgrade.I have at the house some new 0/1ga welding wire that I plan to install as soon as all the fuses and such come in form KnuKoncepts, but I would like to hear some thoughts to make sure I do something different this time. I have two new amps that I want to install and it will be drawing a lot more current, so the last thing I want to do is screw up something with my new set up.Opinions welcome and thanks.I can take a pic later, if that helps.

A wire melting is a good sign of over-voltage or the wire just isn't thick enough to handle the power going through it.
October 1, 200915 yr Author Right now I have the following Fosgate equipment2 1000.1bd1 450.4I have 4ga power/ground throught, Optima red top under hood and Optima yellow top in back. One more yellow top for the new install, but n/a with this problem.
October 1, 200915 yr sounds to me like to much of a load for 4ga wire but im no pro..lol id do upgrade to 1/0 asap,.... and have you done the "big 3"? i havent yet but im planning on it, its said that its one of the best ways to get the most from your electrical system
October 1, 200915 yr Author 4ga for 2500wrms?you need to upgrade that.LOL! Waiting on fuse holders and such from Knu should be here soon.Yea I know that. Like I said voltage was pretty damn good (maybe too good), so I was procrastinating in hope of cooler weather. Main thing is I am surprised it's at the ground. That's why I asked the question.
