About how much more do I need?

I know I need to order a lot of wiring. I want to run my new setup with new wires. I have 13ft of 0 gauge wiring but it is too short to run from my main battery to the battery in the trunk so I am going to use it for the big 3.

Amps-

Two PA a3000db

How much 0 gauge wire do I need to run from the battery that is in the back of the car to the battery that is in the front? Im thinking about just ordering about 30ft.

I'll probably order about 10ft of 4 gauge wire to run from the battery in the back to the amps.

And I need two fuse holders to run these amps, correct?

as for the wire for the batteries, i'd measure how long on the outside of your car, then add about 5-10 ft to that. unless you want extra wire for anything later on. but i'm being cheap as i'm on tight budget right now.

Order 25 ft.

Why 4 gauge to the amps?

always better to order more wire remember that. You def don't want to come up short on the wire and have it be useless again. 13ft should be more than enough for the big 3. An as dkguitarist said I would take the length and again add 5-10ft. If you ahve leftovers you can always get rid of them on here. People are always looking for wires. You can do 2 fuses or I believe 1 fuse then into a distro for the 2 amps

i like to keep my amps separate. their own power, ground and fuses. if anything happens, i can still have the others working. seeing that the amps will be getting power from right next to them, you'll only need one fuse in line (most single battery applications should be fused at the battery under the hood ((to cut the curent if something happens to the wire) and then again at the amp for its protection) speaking of...also remember to fuse or breaker you 0g at each battery. that way if something were to ever happen to the 0g between the batteries you won't start on fire.
