Thanks for the help. The 2/ runs of 1/0 are going to a 2nd battery in the rear, and off the battery another 2 runs of 1/0 to the amp.
Should I fuse the 2 runs of 1/0 coming off the 2nd battery to the amp each with a 150a fuse?
And also, I was looking over the alternator wiring my truck. The stock alt wire runs into a PDC (power distribution center) where all the fuses and relays are. It doesn't go directly to the battery. I also plan on running 2 runs of 1/0 off the alt to the battery and have a few questions.
1. How should I do the wiring? Should I run the wires to the battery or to the PDC, or one each?
2.Should I remove the factory wiring as its small gauge, I mean will I burn it up with the HO alt?
3. The amp needs a 300a fuse rating as well, with the 2 runs of 1/0, should I also run a 150a fuse on each strand?
Thanks again, Dan.
