1/0 without the big 3

Have you known anybody, or it could be you has used an 1/0 gauge or bigger without doing the big 3? //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

its been done and can be done... but you wont have the full potential of 1/0 so might as well do big 3

or at least a fat run of negative to the chassis of your car.

i have 1/0 power and ground and dont have big 3 done. i dont have any dimming or huge voltage drop so i never really cared to hassle with the big 3. i think ill do it eventually

i also didnt install my wire i bought the car with it already wired up.

At a lot of shops it is pretty standard practice to not do the big 3 even if running 0 gauge. But the question is why wouldnt you? It has proven to help and it is pretty easy to do.

see im the type that unless im running a wire to a battery or checking/changing my oil i look at an engine and i got whoa dont wanna touch that i dont wanna break anything.

i heard connecting one of the big 3 to the +battery post stops all dimming problems ?

Im not sure if this is serious or not but I would be more worried about the grounds than the positive. Unless you have a high output alternator.

If you can change your own oil you should be able to do the big 3. There isnt much you can break.

you are allways suppost to have a better grounds to your car then to your amps right?

im running 1/0 to my brutus 1606d without big three i have my ground wire down to about 6 inches

Im not sure I understand your question but all grounds run to the same place in the vehicle.

But factory grounds are almost always a weak spot in electrical systems.

that is my point, when you upgrade a ground any ground past the size of your battary alty ground its not good for the car if im not mistaken.

Current follows the least amount of resistance. Doing the big three makes all power and ground go through it. Less resistance equals less heat and less load on the stereo equipment.

The only time you run into a problem with too big is when you are increasing current into your factory fuse block which is why you run the alternator directly to the battery instead of the fuse box.

Also note your ground or anywhere in the electrical circuit will only be as good as the worst part so it isnt necessarily beneficial to do it half *** but it wont hurt the car.

Yes not doing the whole thing is like kinking a water hose.
