Coming from my truck to my car I don't have enough wire to do what I wanted to. In my truck I had two batteries linked with some 4ga but since they were under the hood it did not to be a larger gauge. Now in my car I'm going to put the yellowtop in the trunk but I have to link it with the one under my hood I should use 0gauge because of the increased resistance. I have wiring from my truck but the 0gauge I have is too short. I do have a distribution block that goes from 0gauge to two 4gauge. Think it would be fine to run 0gauge from the battery to my distribution block out into two 4gauge and then connected to the other battery. I'm going to run 0guage from that to the amp..
