Okay so I have a 2007 Tahoe and it has 2 battery trays up front so I went ahead and orderd 2 Xs d3400's for the 2 front batts and then a d3100 for the rear. Now the problem is my stock battry is on the right side( if sitting in car) but my alt is on the left side of the engine by where the 2nd battry is now I ran 2 positive 0 gauge runs of that 2nd battry and did the big 3 cause it's cause its shorter distance to my alt.......now would my starter battry be doing anything?or is there anyway I can include it in?

Just connect the 2 batteries with a 0 gauge + as well and do the big 3 on both batts

So your saying do 2 big 3's and then I have carol 4/0 gauge I can run positive to positive that will be mint? But my power wires on the 2nd battry that wont cause any issues?
