High Amp Alternator Charge Wire? Hey Guys, I'm installing a 220amp alternator and I'm looking to upgrade the charge cables. Anyone know of a kit for a 2001 Trans Am the output? Or maybe a DIY link I can reference? I'm thinking its 4AWG that will do the trick, but I'm finding some conflicting info.
4 awg will be fine. Be careful.... it starts off as just an "alt upgrade and big cable" but then quickly turns into something else. See here:

220a is kind of on the limit of what 4 ga is capable of carrying. If you haven't beefed up the grounds I would seriously consider upping that to 2 or 0 gauge. Even if you had upgraded the grounds I'd be a little leery.

I'm running a dual 450 in tank setup and a few fans for the procharger, but that alone isn't my real concern. I have 2 JL audio amps 600/1v2 and 400/4 v2 Those 2 alone have a fuse rating of 90amps plus the roughly 34amps combined from the 2 pumps is where I start to get a little worried about the stock setup.. Should I connect the alternator and fuse to their own ends and stack on the battery or connect like they do from the factory? I would think at 4 gauge stacking would be better on their own termination points..

1/0 gauge from battery + to the junction post with ANL fuse right off the battery
1/0 gauge from battery - to chassis ground in trunk.
4 gauge to starter
4 gauge to alt
4 gauge to +post on fuse box
It's called techflex. It's stuff I use in my stereo installs. Its abrasion resistant, and visually blends into the factory harnesses better than just a bunch of different color jacketed wires.
All of my connections have hydraulic crimped copper lugs with adhesive lined heat shrink. Should be a permanent connection and never have any corrosion.

Not only is that not necessary in a trunk mounted battery relocation like I have, you would actually want to run a different gauge wire if you are comparing a 20ft length of wire to a 3ft length of wire. So if I had a 20ft length of 2 gauge running from battery up to alternator then i would only use say a 4 gauge from alt to chassis ground or in my case as in every ls f body the alt grounds to the block and there is already a 4 gauge grounding the block to chassis
