what fuse type

[BlactimusCrime 10+ year member]

So the 100+A that the wire can still safely handle is wasted? I guess you like wasting your money bro.....

Not at all, bc the draw from batt to batt should never be that large when youre running 2k and a 100a alternator.

I fuse for load, not for the wire capability.

Over fusing for the load fries ****.

How do you figure? 2000W amp has the capability to draw around 200A at max. You'd run high risk of blowing a fuse, however music is dynamic, which is why you probably haven't.

The load is fused, via the amp. If he had an amp that didn't have internal fusing, I would be all for fusing the load, but there is NO POINT in this case. And fusing a 150A fuse on a 250A wire is just stupid, sorry man.

Thats true, thats why I have a 200 between my amp and back battery. there should NOT be 200a draw from front to back. just doesnt happen.

false. why not have 2x the protection. if you arent going to draw 250a why use a 250a fuse even if the wire is capable of 250+?

There isn't going to be any difference in the amount of protection you have. What is going to happen between the wire between the two batteries? The only possibility (that I can think of) would be it grounding out, and it would pop the fuse all the same.

surging is a slight possibility, which isnt a good thing either.

Where's hello and keep hope alive to give a detailed reason as to why someone is wrong here?

False. Alt does not "produce" power, it acts as a tender for the batteries. But I understand what you are saying.

So there's going to be a random surge between two batteries, but nowhere else in the circuit? No.

true. but there is fusing elsewhere in the circuit too.

In a typical situation the atlernator is what powers the amp and the battery acts as a filter and really only sustains power at 13-12 volts. if you have two batteries then the second acts as a filter to keep dimming at bay up front and provides a sustained 13or so volts for the capacity of the battery. The cable charging the back battery is drawing a steady amount of power for the most part and it doesnt see the full amp draw as the battery is covering the power draw. If the wire was commanding the full 200 amps then the car would die and so would the front battery.

The rear battery is to back up the alternator to essentially slow voltage drop while the alt charges the electrical system, obviously not everyone runs a 250A HO alt on a 2000W system that draws a total of 250A.

If you're running 10kW, you'd need 1000A of alternator to virtually see no voltage drop. No one has the space for that kind of alternator power and alternators do not come in that size. That is where batteries come in.
