so hears my thought(s), i want to run 2 runs of wire for + and - 1 is my old CCA wire the other is my new OFC, i was thinking the load would just be blaalenced over the two and the OFC would take the over head if i ever ran that much power. CCA (250 amps) the OFC (375 amps) so 625 amps total and my max draw ATM is 300 + 60 = 360 amps total theritacl draw. i am hopeing this will help with voltage drop.
so my main question is would my system care if i mix and match CCA and OFC? and any other thoughts you may have on this.
i don't see it being a problem but i wouldn't do it personally. they both carry a different resistance and the copper would take most of current. i'd take out the CCA. the OFC can handle the theritacl load anyways.
If you want to run two runs OFC for + and 1 run one CCA for -...I recommend this. Run the OFC to a distro-block for the + on your amps. For the - run of CCA, run it to a distro also, but ground the distro to the frame/body in the back of the vehicle...then come off the distro to the amps - inputs.
If you are running a batt in the rear (and I hope you are given that you are running 3k+ wrms), use the batt as your - and + distro block.
So you would have one run of + and one run of - for each the ofc and cca right. If that is the case I honestly don't think it will matter. Either way the power will get back there. However i have used basically that same amp and i remember with out any batteries next to it it was a joke. I would just keep the same amount of - as + and it should be fine.
