Experts on 2500d's

I was about to order all the wiring and stuff last night for my system, but i was talkin to a guy and when i told him how i was going to wire it he told me a completely different way. Since then i've talked to a few people and i'm getting all kinds of different answers so i want to see what you guys think i should do.

I was going to do a run of 1/0 from the alt to the batt positive, then a run of 1/0 from the batt positive to the back into a 250 amp fused block that splits into two 4, two 4 guage from the amp ground to a unfused block that goes to 1/0 then ground that on the floor, then do 1/0 from the batt negative to somewhere like the fenderwall, then do 1/0 from engine to chassis.

One guy that told me i was wrong said that i should do two 1/0 runs to the back into reducers, and run two 1/0 runs (also into reducers) from the amp ground to batt negative, and bring the engine wire to the batt neg but leave the fenderwall to batt negative

I talked to one guy and he said good luck with reducers because he tried to use stinger ones into an orion and they didnt fit so can you guys please tell me the best way to wire this thing because im getting kinda confused now on what to do.

I would do it exactly how you wanted to do it in the first place.

do it the way you have it, but insted of having a fused distro just use a normal distro and fuse it at the batt with a 300 amp fuse.

yeah fuse at the battery. run 1/0 to the amp to a fused distro, then 2 runs of 4 gauge to power and 2 runs of 4 gauge grounds. that's how i had mine. always fuse anytime you drop in wire size.

Yep, a single run of 1/0 guage power and ground will be fine. Ran to the unfused distro block, and fused up @ the battery with a 250a.

You would have to file the reducers down to get them to slide in to the terminal. It's not that much work.

I recomend 2 runs of 1/0, but you can fully get away with only one.

I just 300 amp fuse because thats what the manuel says, but 250 should be more than enough.

A run of 2/0 would be a good idea too.

Yea, i meant to add in fusing at the batt. But, how would you guys recommend doing two runs of 1/0 if i chose to take that route or how do i run 2/0 because i haven't come across any 2/0 wiring accessories other than RF and its really expensive.

2/0 welding is the same as other companies 1/0....
