IS THIS SAFE ???

[Miguels]

just because you run a smaller fuse it doesnt makes things better. if your gear pulls more amperage than what the wire can take get ready to buy a new car.. wire will melt and ground out and you can kiss your car good bye.. there is a reason people use bigger wire regardless of the stock wire size... electrical is an area you dont want to cheap out

[White Lightning]

Simply put, energy follows the least path of resistance. Which is why most people use larger cable for this task.

Yes, you can leave your stock wiring alone and add to it.

You want to prevent voltage drop, not necessarily make stronger output voltage. My suggestion would be to upgrade all of your "under the hood" ground cables with nothing smaller than 2g wire. For starters, 4g wire should be fine to get you started ... But upgrade first chance you get.

This system has already been very expensive and I'm not wanting to waste any more money if something else would do.

If you're running expensive equipment, why hamstring it with CCA wiring and just a 4 gauge lead to the batts?

Honestly, if you're that thin skinned, perhaps the interwebs isn't a place to ask for advice.

4G OFC is .60 more a foot than 4G CCA. $9 more for a 15 foot run.

I won't do, it's not enough. Upgrade to the OFC or better yet go 0g. You can away with CCA if you use 0g.

I'm not that thinned skinned. Those comments just came very unexpected. I have had my systems installed by shops in the past and wanted to do this one myself and make sure it's done right. And ya after reading the comments I guess it would be dumb to cheap out on wire after spending a good deal on the rest. Thanks for the help guys! I'll definitely run 0g

And i'm going to run JBL 1001ez amp with 2 JBL 12's in a custom box.

I saw Steve Meade on his YouTube channel bench the 501ez and it got 750 certified so I'm hoping my 1000 will do as well

Ya i've looked around but couldn't find out any real numbers on CCA vs OFC. I'll get 4g OFC for amp power and use some 0g for big 3

What size fuse should i put on the 15ft 0g CCA run? I think I read somewhere 250 is whats usually used

Should 12g speaker wire be fine for 1k to 1.4k ?

4G OFC is rated at around 150amps

0G CCA is around 250amps

0G OFC is around 300amps

You should fuse for the output of your alt.

Not necessarily for the big 3. The fuses in the big 3 are just there to prevent the wire from moving more current than it is capable of. If you fuse to the alternator's output, you're just limiting the amount of current that the fuse will handle more than you need to.
