Big 3 Question

No, you can use different grounding points.

And please don't listen to this guy \/

Everything you said confirms what I was thinking... especially about the two parts of the big three lol. Thanks!

Lol, some of you audio e-xperts make me laugh... Why would car manufactures put a cable inbetween the alternator and battery that is incapable of carrying the current the alternator is capable of producing, creating an obvious fire hazard? Most cars use a 3ft run or less of 8 awg cable for the alternator positive, which is good for 105 amps... does your cars alternator put out 105 amps? I doubt it, and if it does, it uses 6 awg or better, which is good for 140+ amps. If you want to add (keyword) a huge cable to your alternator, creating more resistence, and more load, and if you aren't fusing (which most e-xperts aren't) your also adding a fire hazard, gj.

Like I said, this applies to stock alternators, any alternator that puts out more than oem, should be upgraded, and even then, 4 awg cable is good for 200 amps in 3 ft runs.

Stop being retarded and trying to catch people on fire.

Actually, my stock alt puts out 110a, and I'm fusing a 300a between the alternator and battery.

From the looks of your pics, your stock cable is 4 awg, which will do 150 amps+ CONSTANTLY, which your amp doesn't draw, nor does your alternator put out 110 amps constantly (or ever most likely). Its good that you fused though, although I would use a smaller fuse just to be safe, your battery might not do 300 amps for long enough, as it will take awhile for a 300 amp fuse to heat up enough to pop, in which case your wire might already be melting.

Your a fucking idiot if you think doing the big 3 will add resistance or a larger load. I think you need to do some reading on basic electrical theory before you start running your mouth.

Adding 1/0 to his stock alt wire will only DROP the resistance from the alt to the battery, thus allowing MORE of the current to get there. With the dinky *** stock wires there is a significant amount of loss so even though the alt may be producing 100A, the electrical system is only receiving 90A (just a hypothetical example). Doing the big 3 reduces the overall resistance in the electrical system and if you did it and caught your car on fire then obviously your a dumbass to begin with and need to find a new hobby.

This is ridiculous, I guess there's no point in trying to argue with Internet hypsters... There's no way in hell a 10 amp loss comes from wire, period. The only way an improvment would be found is in fixing corroded terminations... That is all.
