Thanks for the fast replies by the way. So you are saying that instead of running the - wire to the engine I should bolt it to the case of the alt?

Yes from battery to alt case

OK sounds good. Is the way I have it now wrong?

Not really wrong ..just the alt case is better

Electrically it's the same point. You can always fuse it closer to the amp and again close to the battery.

^^well thats the biggest fail of the day

As you mentioned, you have a unibody car. That means you do not have a solid frame to ground to. You should run your negative from battery in trunk directly to battery under the hood.

Yes its unibody bu there are sufficient ground points in the rear suspension of this car ...no need to run a negative run all the way to the battery ...i have a 08 impala and all my rear grounds test perfect with dmm

Hey guys, I just did a re-ground on my SAZ 2500d in the trunk by drilling in the frame and the dimming has almost disappeared. Since it still dims a little if I turn it up all the way will I need another battery or is this normal? Voltage drops down to low 13s but quickly goes up to 14.4v. Tell me what you guys think

this. so many people here want to waste money and effort on so many **** runs, especially negative.

op, pick up a batt for the rear.

and ground it to the same location

I have an XS Power D3400 up front that has been used for about a year. I heard you cannot use old and new batteries together without an isolator. Will I still be ok if I don't use one and wire a XS D3100 in the back?

That's fine as long as your not playing with the car off
