Fusing the new setup

[PUNKYOU007]

So if i do one run of 1/0 from each alt and one from the front battery (giving me a total of three runs from the front) i need to:

1) Go from each alt to a 325A fuse

2) Go from the front battery to a 325A fuse

3) From each 325A fuse to the rear batteries

4) From the rear batteries into a 380A fuse

5) From each 380A fuse to each amp

In my case i will either be running AQ3500D.1 or Cadence ZRS-C5 for the subs.

The AudioQue site recommends a 380A inline fuse. The 3500 also accepts two 1/0 positives. Should i run a 380A fuse for each positive connection on each amp?

For Example: I am running two AQ 3500D.1's that would give a total of four 1/0 positive terminals, two on each amplifier. I would have to run four 380A fuses between the rear batteries and the amplifiers.

OR

For Example: I am running two AQ 3500D.1's that would give a total of four 1/0 positive terminals, two on each amplifier. I would have to run four 190A fuses between the rear batteries and the amplifers

Help here would be well appreciated.

Every cable that comes off a battery's positive terminal should have a fuse within 1ft of the battery. And a 380A fuse will take around 700A to blow it, if you're using long runs of 0 gauge this is NOT good. I use 250A fuses on long runs of 0.

Up front i need to fuse for the wire, correct? thats where the 325A fuses come into play.

and basically i was just wondering if i need to fuse in the rear by the amps? Those particular amps call for a 380A fuse but they have two positive inputs.

how should i tackle this?

If you are hooking the amp up directly from the front battery, you will only need a fuse up near the front battery. If you are having a run from the front battery, to a battery in the back, to the amplifier. You will need a fuse near the front battery, with a fuse on the same wire near the back battery. Then with the wire coming off of the second battery to the amplifier you will need 1 fuse.

325A is the max size fuse you can put into 0AWG, but I wouldn't recommend doing that in a long run (front to back), only a smaller wire (like back battery right beside the amp). You said the AQ3500D has 2 positive inputs, right? If that is the case, and you run the amp straight off the front battery, just use 2 runs with 300A fuses. If you are going to run it off the back battery right beside the amp, I would say 2 runs with 325A fuses will be safe.
