    Hey guys, So I am kind of a car-audio guy. But most of my work in car-audio was 20years ago when things werent as advanced.

    So I've heard if you update the ground cables (thicker wire) on your battery it can help the performance of your battery. Which makes sense...

    Now, I dont want to change the wires that go to my alternator and my engine chassis, but the ground wire on my negative looks like it is 24 awg. Really thin crap wire. Its only about 3 inches long too.

    Has anybody else heard or changed the ground wires on their battery, and does changing the negative ground, mean I should change the other ground(to my engine). I dont want to screw anything up.

    To get the full benefit of better grounding you need to do all 3 portions of the 'Big Three'.

    what he said. do the big three. it will help your power alot. its stupid that they use such small wire when dealing with the battery and alternator. if you want i can link you to a pretty extensive write up on how to do the "big 3". im a car audio guy as well.

    I have read some updates with using 0 guage and what not.

    I was just worried that if I un balance the battery cables it will hurt my load. The alternator and + ground chassis seem to be pretty decent size. Probably 10guage.

    But the negative ground is terrible, litteraly like 24 guage. Really LQ wire.
    I was considering upgrading to 8 guage for that specific ground.

    The "Big Three" are the white cable on the + side, and the other is kind of hard to see. But the one i want to change is on the far right under need my amplifier power cord(its got the black insulation on it)

    Anyways, as you can see, its a little shitty ass wire and about 3 inches long haha. I want to change that. But dont want to screw anything up...
