Alt to bat run

[emperorjj1 2]

I was wondering if i should do another run of wire from the alt to the bat? This is for my second alt to the batteries in the trunk. Right now i have a single T30001bd amp and a single run of 2/0 and i was looking at getting a second T30001bd amp. If i go ahead and get the second amp should i do a second run of wire?

also i barely would have enough 2/0 for a second run. So assuming i do a second run of wire should i use it for that run and connect my 2 batteies in the back with 1/0? or what should i do there? I dont think i can find any more fosgate 2/0

yes, that would be fine.
